The pages to scan first are the ones with the highest traffic, the highest conversion value, and the broadest template coverage. Start with the homepage, top landing pages, primary conversion paths, and one example of each unique page template across the site. Scans only flag approximately 25% of issues, but starting with these pages gives you the fastest read on where automated detection picks up the most signal. From there, expand scanning to secondary templates and lower-traffic pages over time.
Scan coverage should mirror how visitors actually move through the site, not the order pages appear in the CMS.
| Priority Factor | Why It Matters |
|---|---|
| Traffic volume | Higher traffic pages expose more users to any issues present |
| Conversion value | Checkout, signup, and lead forms carry the highest business risk |
| Template coverage | One scan of a template often reflects hundreds of similar pages |
| Legal exposure | Public-facing pages tied to goods and services draw the most claims |
| Update frequency | Frequently edited pages need recurring monitoring after the first scan |
Start with the Homepage and Top Landing Pages
The homepage is the most viewed page on nearly every website. It also tends to use components that repeat across the site, including the main navigation, the footer, search, and primary calls to action. A scan of the homepage gives you signal on global elements that affect every other page.
After the homepage, pull your top ten landing pages from analytics. These are the pages real visitors arrive at most often from search, ads, and referrals. If a scan flags an issue on one of these pages, the impact reaches a meaningful share of your audience immediately.
Why Should Conversion Pages Come Next?
Conversion pages carry the most weight because issues on them block the actions that generate revenue. A scan of the cart, checkout, account creation, contact form, and any gated download page should follow your top landing pages.
These pages also tend to draw the most legal attention. When someone cannot complete a purchase or submit a form, the business impact is direct and documentable. Scanning them early gives the development team a head start on the issues most likely to surface in a demand letter.
Cover Every Unique Template Before Going Wider
Most websites are built from a small number of templates repeated across many URLs. A blog might have one article template powering 800 posts. An ecommerce site might have one product template powering 2,000 SKUs. Scanning one example of each template is far more efficient than scanning every page of the same type.
Make a list of the unique templates on the site: homepage, category page, product page, article post, author page, search results, contact, about, login, and any specialty templates like pricing or comparison pages. Scan one of each. The patterns the scan picks up on one product page will almost always repeat across the others.
Factor In Legal Risk and Industry Exposure
Some industries see more accessibility-related claims than others. Ecommerce, restaurants, healthcare, and financial services consistently appear in lawsuit data. If the site is in one of these categories, weight your scan priorities toward the pages where transactions happen and where customers interact with services.
Public-facing marketing pages, the storefront, and any form that captures customer information should all be scanned in the first pass. Internal admin tools and authenticated dashboards can wait until later phases.
How Many Pages Should the First Scan Cover?
A reasonable first scan covers somewhere between 15 and 50 pages, depending on site complexity. A small business site might be fully represented by 15 well-chosen URLs. A large ecommerce catalog might require 40 to 50 to cover every template and key conversion path.
The point is not volume. The point is representative coverage. Twenty pages selected with intent will reveal more useful information than 200 pages selected at random.
What Scans Will and Will Not Tell You
Scans flag approximately 25% of WCAG issues. They are useful for catching certain categories of issues quickly across many pages, especially missing alt text, color contrast, form label associations, and obvious heading structure problems. They do not evaluate keyboard operability in depth, screen reader output, focus management, or the many issues that require human judgment.
For determining WCAG conformance, a (manual) accessibility audit is the only method that produces a reliable read. Scans serve as a monitoring layer between audits and as a way to catch regressions on pages that change often.
Building a Repeatable Scan Schedule
Once the first round is complete, set a cadence. High-traffic and frequently updated pages can be scanned weekly or monthly. Static pages can be scanned quarterly. New templates and new landing pages should be added to the scan list as soon as they go live.
Accessible.org recommends documenting which pages are in the scan rotation, what cadence each page follows, and who reviews the results. Without a documented process, scanning becomes inconsistent and the data loses value.
Which pages should I scan first if I only have time for ten?
Homepage, top three landing pages by traffic, the primary checkout or signup flow (two to three pages), contact form, one product or service detail page, and one article or blog post. That combination covers global components, top entry points, conversion paths, and the two highest-volume templates on most sites.
Should I scan authenticated pages behind a login?
Yes, but in a later phase. Public pages reach more users and carry more legal exposure, so they come first. Authenticated areas like account dashboards, settings, and member-only content matter, especially for SaaS products, and they should be added once the public pages have a documented baseline.
How often should I rescan the same pages?
Match cadence to update frequency. A homepage that changes weekly should be scanned at least monthly. A product template that rarely changes can be scanned quarterly. Any page that goes through a major redesign should be rescanned immediately after launch.
Can scans replace an audit for the pages I prioritize?
No. Scans give partial coverage of automated-detectable issues. Conformance to WCAG 2.1 AA or WCAG 2.2 AA can only be determined through a (manual) audit conducted by trained auditors. Scans complement audits, they do not replace them.
Choosing the right pages to scan first is less about the tool and more about understanding which URLs carry the most weight for your users and your business. Get that prioritization right, and the rest of the scanning program follows from it.
