Hi Rakesh,

I recently worked on an accessibility evaluation for a recently redesigned
association web site. Now, the full site has around 60,000 pages; there are
many, many content editors updating different areas of the site.

Because of the limited budget of the project, we reviewed a sample of 15
pages across the site, chosen by the client. While focusing on most popular
pages certainly makes sense, our samples were chosen in an effort to ensure
that the main content areas (each edited by a different group) were
represented. That way, no one could look at our results and think, "well,
that's a problem for THAT group, but not for ours." That was the thinking
behind choosing the sample, anyway.

What we found was there were two different types of accessibility errors:
errors in the design and errors in the content.

The "design" errors (such as text links that were styled so that the
underlines were removed) were located in the page templates, CSS, etc. These
errors would need to be corrected by folks with specialized knowledge or
access to fix these global issues. And because they were global, fixing them
once fixed them everywhere.

The "content" errors (such as poorly chosen or missing alt text) were
usually introduced by the content editors themselves. These are easy enough
to fix once the content editors understand what the errors are, how the
affect accessibility and how to fix them. The problem is, content errors are
very easy to reintroduce.

So by all means, do an accessibility review on a selection of pages. My
suggestion would be to consider your popular pages, critical tasks,
different page types (forms vs. pages, for example), and the different
content editors in your sample.

Where you find global issues in the design, fix them. Where you find errors
introduced by the content editors, focus your accessibility training efforts
to address the types of errors you're content editors are making.

Hope this helps,
