A fee on a statement. A finding in an audit. A term in a software proposal. Find out what it means, where it fits in your business and what to check before you decide.
Payments, websites and AI, with practical examples and guides for the detail.
An acquirer is a payment service provider that enables a business to accept card payments. It supports the processing of transactions through the card payment system. The business taking the payment is usually called the merchant.
In practice
A shop may buy its till software from one company and have its card-acquiring agreement with another. Those companies can have different support teams, charges and responsibilities.
Why it matters
Identifying who supplies each part of the setup helps you ask the right company about a payment, a fee or a technical connection.
An AI agent uses a model and connected tools to work towards a task, choosing actions within the access and instructions it has been given. Its capabilities depend on the tools, permissions and controls in the particular system.
In practice
An agent could inspect an incoming enquiry, look up an approved service description and prepare a response for a member of staff to review. Permission to prepare a draft need not include permission to send it.
Why it matters
Discuss the actions an agent can take, the records it uses and when a person must approve the work. The label alone does not establish what a product can do.
On this site, AIO means considering how business information may be discovered and used in AI-generated answers. Providers also use terms such as answer engine optimisation and generative engine optimisation. These labels do not describe one universal test or scoring system.
In practice
Checking whether a service page contains accurate information is one task. Recording whether an AI platform cites it for a particular question is another, with different evidence.
Why it matters
Ask what is actually being checked or measured. Google says no special AI files or schema are required for AI Overviews or AI Mode, and eligibility does not guarantee inclusion.
An application programming interface is a defined way for software to interact with another system. An API describes the requests that can be made, the information expected and the responses available. Access and permissions are part of the arrangement.
In practice
A website enquiry form could use an API to create a record in a CRM. The connection needs to handle missing information, duplicates and a request that fails.
Why it matters
Before buying an integration, confirm the exact actions supported and who will manage access, errors and changes. An available API does not mean every desired workflow is already built.
Automation uses technology to carry out a task or sequence with less manual intervention. A workflow may follow fixed rules and require no AI at all. Its usefulness depends on the work it replaces and how exceptions are handled.
In practice
After a customer submits an enquiry, a rule could assign an owner and create a reminder. A person can still decide what response is appropriate.
Why it matters
Describe the trigger, the action, the exceptions and the person responsible. Measure the complete process, including checking and correcting it, when deciding whether the automation helps.
Blended pricing groups underlying payment costs into quoted transaction rates instead of automatically passing through each transaction’s interchange at cost. A quote can contain different blended rates for different card or transaction groups.
In practice
A café might see one rate for consumer debit cards and another for commercial cards, with terminal rental and other charges listed separately.
Why it matters
The quoted percentage may describe only part of the bill. Compare the covered transactions, fixed charges and contract terms using the same trading assumptions.
A canonical URL is the preferred address for a page when duplicate or very similar versions exist. A canonical annotation tells a search engine which version the site prefers. It is a signal, and the search engine can select a different version.
In practice
A service page might be reachable both with and without a tracking parameter. A developer can check whether the canonical information points to the intended main address.
Why it matters
An unexpected canonical can send a confusing signal about an important page. Establish the relationship between the versions before changing it.
A chargeback is the reversal of some or all of a card transaction through the card scheme’s dispute process. It involves the card issuer and acquirer. The grounds, evidence and process differ from a refund agreed directly between a business and its customer.
In practice
If a customer disputes a payment, the provider may ask the business for the transaction record and evidence of what was supplied. A completed sale is not the whole dispute record.
Why it matters
Follow the provider’s instructions and deadlines for the actual case. Keep clear transaction records and make the relevant refund or cancellation terms available to customers.
A conversion is a defined action you want to measure, such as a completed enquiry or booking. The definition should name the event being counted. A page visit, a button click and a submitted form are different events.
In practice
A salon could record visits to its booking page separately from completed appointments. Counting every booking-button click as an appointment would overstate the result.
Why it matters
Agree the measurement before comparing changes. A useful website review connects what people do on a page with the task the business actually wants to support.
Crawling is the process of discovering and retrieving web content. A search crawler may follow links or use other discovery information. Retrieving a page is an earlier stage than deciding whether to index it or show it for a particular search.
In practice
An audit tool may retrieve a service page successfully while Google’s indexed information still reflects an older version. Those are observations from different systems and times.
Why it matters
When investigating a missing page, distinguish access, indexing and search results. A single successful request does not establish all three.
Customer relationship management describes how a business organises its relationships and interactions with customers and prospects. A CRM system stores information such as contacts, conversations, ownership and agreed follow-up in a shared place.
In practice
After speaking with a potential customer, a team member could record the discussion, assign the enquiry and set a reminder. A colleague can then see what has already been agreed.
Why it matters
A system is useful when the records stay relevant and people know who is responsible. Importing a contact does not by itself create a relationship or establish permission for every use of the data.
The Domain Name System translates human-readable domain names, such as example.co.uk, into the network information computers use to locate services. Website hosting, email and other services can depend on different DNS records.
In practice
A business moves its website to a new host but keeps email with its current provider. The person making the DNS change needs to preserve the mail records while updating the website destination.
Why it matters
A domain can be registered and still point to the wrong service. Check the specific records and the intended website or email change before editing them.
For a card-cost comparison, an effective rate expresses the selected fees as a percentage of card turnover for the same period. Calculate it by dividing those fees by that turnover and multiplying by 100. State which charges are included.
In practice
Illustrative calculation: £150 of included fees divided by £10,000 of card turnover is 1.5%. If equipment or other charges sit outside the £150, this is not an all-cost comparison.
Why it matters
Using a consistent period and scope makes quotes easier to discuss. The result still depends on card mix, transaction sizes and the terms being compared.
Electronic point of sale is a till system used to record sales and support the work around them. Depending on the software and setup, it may also manage orders, stock, staff access or reporting. Payment integration is a separate compatibility question.
In practice
With a supported connection, a restaurant’s till can send the bill amount to the card machine. Staff need both suppliers to confirm how refunds, tips and reporting work in that setup.
Why it matters
Choose around the tasks your team performs. A till and a terminal being available from familiar brands does not establish that their exact products and versions connect.
First-party data is information a business collects directly through its own interactions with people, customers or website visitors. The label describes how the information was obtained; it does not remove privacy, transparency or security responsibilities.
In practice
A customer gives a shop an email address to receive a receipt. Reusing that address for a different purpose needs its own review of the circumstances and applicable rules.
Why it matters
Record why information was collected, what people were told and how it will be used. A direct relationship can provide context, but it is not blanket permission for every later use.
Googlebot is the name for Google’s web crawling software. It requests pages and resources that Google may use in Search. A page being fetched by Googlebot does not by itself mean that Google will index it or show it for a query.
In practice
A developer sees a successful request for a service page in the server logs. They still need to check the rendered content, indexing instructions and Search Console evidence to understand whether it appears in Google Search.
Why it matters
Separate crawling, rendering, indexing and serving results. Each is a different stage, and a check of one does not prove the others.
An AI hallucination is output that appears plausible but contains incorrect or invented information. It can include a false fact, a nonexistent source or an unsupported detail about a real person, product or business.
In practice
A drafted customer reply might confidently include a service price that was never supplied. Smooth wording does not establish that the price is correct.
Why it matters
Check factual claims against the records or sources relevant to the task. Give a reviewer enough information to verify the output before it reaches a customer.
Human review is a deliberate check by a person before work is accepted or an action proceeds. In an AI-assisted process, the review should specify what the person checks, what evidence they use and what happens when something is wrong.
In practice
Before sending a drafted quote, a team member could confirm the customer, scope, price and dates against the approved records, then authorise the message.
Why it matters
A review stage needs time, ownership and the ability to stop or correct the work. A button labelled Approve does not establish that those checks occurred.
Indexing is the stage in which a search engine analyses a retrieved page and stores information for its search index. A page being accessible, or technically eligible, does not guarantee that it will be indexed or displayed for a search.
In practice
After publishing a new service page, the owner could use Search Console to inspect Google’s recorded information for that address. An audit of the current HTML answers a different question.
Why it matters
Use the search engine’s evidence when investigating indexing. Adding more keywords to a page will not explain an unintended technical instruction that excludes it.
Interchange is a fee flowing from the acquiring side to the card-issuing side in a card payment system. It is one component of payment costs. It is not the whole charge a business pays to accept a card.
In practice
A payment quote may combine interchange, scheme costs and a provider charge within a transaction rate, or show cost elements separately. Other account or equipment charges can sit alongside them.
Why it matters
Keep the underlying component separate from the complete merchant bill. The rates and any regulatory treatment depend on the transaction and card involved.
Interchange-plus pricing passes the applicable interchange through at cost and adds the agreed provider charge. Interchange-plus-plus also passes through defined scheme fees at cost. Read the proposal to establish how each component and extra is treated.
In practice
A business could receive a quote with a provider percentage and a fixed charge in addition to underlying costs. That headline provider percentage is not the full transaction price.
Why it matters
Compare the entire arrangement using the same trading assumptions. A pricing-model label alone cannot establish that one offer costs less for your business.
JavaScript rendering is the process of running a page’s scripts to produce or update the content a browser displays. Search systems may render JavaScript, but access to scripts, processing time and other technical limits can affect what they can read.
In practice
A service page looks complete in a browser, but its initial HTML contains only an empty app container. Check the rendered version and whether essential headings and links are present for visitors and crawlers.
Why it matters
Make important information and crawlable links available in rendered page content. Test the actual URL when a page depends on scripts; do not assume a browser screenshot proves search visibility.
A keyword is a word or phrase used to describe a topic a page addresses or a search someone might make. Search engines can understand related language, so a useful page explains the subject naturally instead of repeating a phrase to meet a target count.
In practice
A heating engineer may use “boiler repair” as a planning label, while customers also search for a boiler that has stopped working. The page should answer the service need in clear language.
Why it matters
Use the vocabulary customers recognise in titles, headings and explanations where it fits. A keyword list is a research aid, not evidence that a page is useful or will rank.
A large language model is an AI model trained to process and generate language. It can produce useful drafts or summaries, but its output can also be incomplete, outdated or incorrect. Its behaviour depends on the model, input and any connected information or tools.
In practice
A model summarises a company’s service page. Check that the summary preserves the actual service area and does not add a price or guarantee that the business never stated.
Why it matters
Treat generated wording as material to review against reliable information. A fluent answer is not proof that its facts or sources are sound.
Metadata is information describing other information. On a website it includes elements such as a page title and meta description, alongside other instructions and labels. These can help describe or manage the page without being its main visible text.
In practice
A page may show “Boiler repairs in Sheffield” as its main heading while publishing a separate title and description in its HTML. Those values should describe the same actual service.
Why it matters
A missing or repeated value is a reason to inspect the page. Clear metadata should match the content; it does not replace the explanation a customer needs.
Noindex is an instruction asking a supporting search engine to exclude a page from its index. It can appear in the page’s HTML or an HTTP response header. Google must be able to retrieve the page to read the instruction.
In practice
A preview page may deliberately use noindex. If the same instruction remains on a live service page after launch, ask the developer whether that was intended.
Why it matters
Establish the purpose of the page before changing the setting. Noindex is an indexing control; private information needs appropriate access protection.
Organic search describes unpaid listings shown in response to a search. A visitor can reach a business through an organic result without the business paying for that individual click, although the work of creating and maintaining the site may have costs.
In practice
A customer searches for a local service and visits a company’s page from an unpaid result. That visit can be recorded separately from a click on a paid advertisement.
Why it matters
Keep organic and paid activity distinct when reviewing traffic and enquiries. Search placement and visits can change; neither is guaranteed by a website audit.
A prompt is the input given to an AI system to request a response or task. It can contain instructions, relevant context, examples and constraints. The system’s output also depends on the model, tools and other information available to it.
In practice
A request to draft a booking reply could provide the approved opening hours, the customer’s question and a rule to leave unconfirmed availability for staff to check.
Why it matters
Clear inputs help define the task, but do not make every output accurate. Specify what must be checked and which information the system should not invent.
A search query is the word or phrase a person enters into a search service. It may be a question, a product name, a location or a combination. The same query can produce different results depending on context such as language, location and device.
In practice
Someone looking for card processing might search “card machine fees” while another person searches “payment terminal for a café”. Those phrases point to related needs expressed in different language.
Why it matters
Use actual search evidence and customer language to understand what a page should answer. Do not assume one phrase represents every visitor or repeat it unnaturally.
Reconciliation is the process of comparing records and accounting for differences. In payments, a business may compare till sales, terminal transactions, fees and bank payouts. Those records can cover different time periods or contain different adjustments.
In practice
A pub’s till total may include a refunded sale while a payout reflects transactions from another banking window. The difference needs tracing rather than assuming that money is missing.
Why it matters
Agree which reports, dates and adjustments you are comparing. Supported till connections can reduce re-entry, but the complete reporting and checking process still matters.
Scheme fees are charges from a card scheme operator for participating in its scheme. Processing fees concern services such as authorisation, clearing and settlement. How those costs appear on a merchant’s bill depends on the payment agreement and pricing model.
In practice
A merchant on a blended quote may not see each underlying scheme charge as its own line. Another agreement may pass through defined costs separately.
Why it matters
Ask what is included in the quoted rate and what can change. Keep scheme costs, interchange and the provider’s own charges distinct when comparing proposals.
Search engine optimisation is work that helps search engines discover and understand useful website content and helps people find it through search. It includes technical access, clear content and a site structure that supports the visitor’s task.
In practice
A trades business could explain its services on distinct, linked pages, keep its contact details accurate and investigate an unintended indexing restriction on a live page.
Why it matters
Choose work around the searches and customer decisions that matter to the business. A checklist score is a diagnostic aid, not a guaranteed position in search results.
Settlement concerns completing the transfer of funds through the payment arrangement. Businesses often use payout to describe the money reaching their bank account. Timing, deductions and the transactions included depend on the provider and account terms.
In practice
A business comparing providers should check which sales a payout includes, when the relevant banking window closes and how weekends or bank holidays are treated.
Why it matters
A successful card transaction and money being available in the bank are different points in the process. Use the written payout schedule when planning cash flow.
Structured data is a standardised way of labelling information about a page or the things it describes. JSON-LD is one way to include it in a website. The labels and values should accurately reflect the information people can read.
In practice
A business can describe its organisation with appropriate markup, then check that its name and contact details agree with the visible website. Adding unrelated types would not make that description more useful.
Why it matters
Markup can support understanding and eligibility for relevant search features. Its presence alone does not establish validity or guarantee a rich result or AI citation.
Technical SEO is work on the parts of a website that help search engines access, render and understand its pages. It can include crawlable links, indexing controls, canonical URLs, structured data and page performance. These checks support discovery; they do not guarantee a ranking.
In practice
A business publishes a useful guide but blocks its folder in robots.txt. Reviewing the technical access settings helps explain why the page may not be available to a crawler.
Why it matters
Resolve technical problems that prevent important content from being accessed or understood, then assess the page’s usefulness and relevance as well.
A URL is the address used to locate a resource on the web. It can contain a protocol, domain, path and optional parameters. Clear, stable URLs help people recognise what a link is for and help a site keep its pages organised.
In practice
A service page may have a readable path such as /card-payments/. A tracking parameter can be added to a campaign link without changing the main page’s subject.
Why it matters
Use one intended address for each important page and check redirects and canonical information when URLs change. A URL alone does not explain the full page content.
Vertical search is search focused on a particular type of information or result, such as local businesses, images, products or videos. It differs from a general web search because the results and features are shaped around that subject.
In practice
A customer choosing a nearby restaurant may use a map or local-results view rather than a general list of web pages. Accurate business details can help people assess whether the listing is relevant.
Why it matters
Consider where people actually look for your service and keep the information there accurate. Being present in a particular search feature does not guarantee a prominent position.
A web crawler is software that requests and reads web pages, often following links to discover other pages. Search engines use crawlers to find content, subject to access rules and technical limits.
In practice
A crawler can reach a homepage but fail to discover a guide whose only link is hidden behind a control it cannot use. A standard link with a destination gives both people and crawlers a clear route.
Why it matters
Keep important pages reachable through ordinary links and check whether robots.txt or other access rules block a resource that should be public.
An XML sitemap is a file that lists URLs a site owner wants search engines to know about. It can help with discovery, especially on a large or complex site, but listing a URL does not guarantee that it will be crawled or indexed.
In practice
After publishing a new guide, a site can add its canonical address to the sitemap. The page should still have a working URL and useful internal links.
Why it matters
Keep sitemap entries accurate and focused on canonical pages intended for search. Use Search Console to review crawling and indexing evidence rather than treating sitemap submission as confirmation.
YMYL is Google’s shorthand for topics that could significantly affect a person’s health, financial stability, safety or society. It is a way Google describes topic sensitivity in its quality guidance, not a special markup type or a score a website can claim.
In practice
A page explaining borrowing costs could influence a financial decision. It should define the terms carefully, distinguish general information from advice and link to sources that support important claims.
Why it matters
Take extra care with accuracy, sourcing and clear limits when a reader might rely on information for a consequential decision. No page label guarantees better search placement.
A zero-click search describes a search journey where someone gets enough information from the results page or another search feature without visiting a listed website. It is a description of a possible outcome, not a formal promise that every search works this way.
In practice
A person checks a business’s opening hours in a local result and does not open its website. Another person may still visit the site to compare services or book.
Why it matters
Look beyond clicks when reviewing how people discover a business. Search Console impressions and website visits measure different parts of the journey.
