THE SHORT ANSWER
Read the label, open the destination and compare them. Describe the page or action plainly. Different destinations need meaningful differences, not a new clever phrase for every button.
Look at the page as a set of choices
Start with a page that offers several services or resources. Write down the links in the order they appear. Read that list without the photographs or surrounding paragraphs. Note which ones tell you something useful and which leave you guessing.
This is a way to inspect the wording, not a complete accessibility audit. Context can legitimately explain a link. The exercise helps you find places where the reader is doing unnecessary work to connect a generic label with the right destination.
Keep the actual address beside each label. Sometimes the wording is fine and the link is wrong. Other times several different labels all lead to the same general contact page. Those are different problems, so do not fix both by simply adding more words.
Describe the destination you verified
W3C's guidance on link purpose says that people should be able to determine a link's purpose from its text or its programmatically associated context. Descriptive wording also helps people choose among links without relying on the entire visual layout.
Use ordinary destination language. Read the service options tells someone more than Discover possibilities when the destination is a service list. Request a quote is appropriate when the next page really begins a quote request. It should not imply that a price has already been calculated.
For a download, make the file nature clear when that matters. A visitor should not need to discover that a button opens a document rather than a normal web page. Only include a file size or format if you have checked the actual file.
Avoid promising an action the link cannot complete. A link to an email application is not the same as sending an inquiry. A link to a booking page does not by itself confirm an appointment. The wording should fit the next step, not skip over it.
Keep the same route recognizable
Check other places that lead to the same destination. You do not need identical sentences throughout the website, but the key action should remain recognizable. A customer should not wonder whether Get started and Apply now are unrelated processes when they open the same form.
Choose labels around the visitor's task rather than the internal name of a tool. Someone looking for service details usually does not need to know which software holds them. Explain a move to an outside booking provider when that context helps the person continue confidently.
Do not make a label so long that it becomes a paragraph inside a small button. Put the main action in the label and nearby explanatory detail in normal page text. Check that the relationship is clear on a narrow screen as well as a desktop.
A more descriptive link is not an excuse to change the destination without checking the business process. Ask the person responsible for inquiries or bookings before redirecting customers to a different account or system.
Retest the choice, not just the wording
Open the updated public page and follow the link. Confirm it reaches the intended place and that the destination heading agrees with the promise. Keep a note of any redirect or unexpected sign-in requirement that appears.
Ask somebody unfamiliar with the site which link they would choose for a specific task. Let them make the choice before explaining it. Their hesitation may show that the surrounding section needs work as well as the link label.
For Your Page, a working preview is the place to test those choices before launch. Use the actual links and the intended customer task. A screenshot can show the button's appearance but cannot establish that its route is useful.
For each changed label, record its old wording, new wording and verified destination. Keep the reason for the change in a short note. That gives another editor enough context to preserve the useful distinction when the page is reorganized later.
When the destination changes later, review the labels pointing to it. A renamed service, replacement form or new document can leave accurate-looking wording attached to an old promise. Keep the link and the thing it describes together in the update checklist.
