There was one in the "Tools" 10 to 15 years ago, but I don't remember seeing anything since. Nevertheless, there are a several basic steps you can take to get some points on the board while you search for something more comprehensive.
Generally, most pages of a bank website deliver promotional information, so they are subject to one or more of the advertising rules for deposits, loans, and other services. If you review ads in other media, you might be up to speed on the different sets of regs for deposits, open-end credit, closed-end credit, housing loans and lines, credit cards, student loans, etc., etc., etc. It still won't hurt to do a quick refresher. Web-based ads are subject to the same principles as ads in any other medium, but there are occasional "extras"--like the so-called "one click rule."
Another common element of most pages is the logos and legends. There were 3 regulatory items when I last reviewed bank websites (circa 2007). Housing credit pages should display the EHL "doghouse", but you don't violate any rule if you plaster it on every page on the site. The FDIC membership statement is also allowed on all pages EXCEPT NDIP. Pages promoting NDIP must contain the necessary disclaimer. Your job is to review & approve the graphics and content of these items and declare which ones go on each page in the site.
Another page-by-page quickie is an eyeball test for diversity in any human images used on the site. Unless the regulators have developed preferences, I'd look at the site as a whole--as long as the forest is inclusive, the page-by-page presentation of trees shouldn't be a big issue. Housing credit pages could warrant an exception.
The single most popular way to violate the law with a bank website is with rateboards. I've seen stale rate info from time to time and it's always intolerable. Banks can and should do better. 9 out of 10 violations, however, will come from trigger term/triggered content errors and omissions. The concepts are the same, but the mechanics are different for deposits, open-end credit, and closed-end credit. Before you look at the first draft webpage, know what constitutes each type of trigger term and what must appear when triggered.
After you scan for the superficial stuff, the next level into the site is functionality. Other than reading your ad copy and rates, what can a site user do interactively? If you find credit application forms, then your review needs to consider COPPA, fair lending, and any other reg. that applies to requests for information. If accountholders can sign up for e-delivery of statements and anything else containing federal disclosures, then ESIGN enters the picture. If deposit accountholders can sign up for new types of electronic payments, then consider how Reg. E applies.
If this is beginning to sound like a lot of common sense, then you're on the right track! Go with the flow. There's no right or wrong way to review web content. Look at what's there and base your review and recommendations on whatever regs you determine to be relevant. Also, remember that web content can be dynamic--now you see it, now you don't! Be sure you understand what every given site visitor might see, hear, or experience
