I would not run separate accessibility and SEO audits that ignore each other. On most sites, the same sloppy template problems hurt both.
Broken headings. Missing alt text. Vague link text. Low contrast buttons. Popups that trap focus. Pages that look fine in a design file and fall apart on mobile.
Quick Answer
Audit your highest-traffic templates once for accessibility and SEO together: headings, titles, alt text, internal links, keyboard use, and page clarity. Fix templates before running endless page-by-page reports.
The overlap is bigger than people admit
A page with one H1, logical heading order, descriptive link text, and useful image alt text is easier for humans, screen readers, and search systems to understand.
That does not make accessibility “just SEO.” It does mean a lot of work is shared.
I would start with templates, not random pages
Homepage. Product template. Category template. Blog template. Contact page.
If those are weak, every new page inherits the weakness.
Fixing 300 blog posts one by one while the blog template still has junk headings is slow work.
Do not use accessibility as a checkbox export
I have seen teams buy a report, file it, and change almost nothing.
Same with SEO audits.
Pick five fixes that matter on pages people use:
- improve button labels
- rewrite “click here” links
- add alt text that describes the image job
- fix heading jumps
- make forms usable on mobile
Better for users, better for clarity
You do not need a philosophical debate to do this.
If a page is clearer for a human, it is usually easier for search engines to interpret too. Start there.
