I was reading some of my news feeds and came across this great site called http://webdevchecklist.com/.
It is a creation of Sayed Ibrahim Hashimi and Mads Kristensen. I often publish a site and run through a few tests. Some I do religiously, but others I often forget. The list they put together lets you pick and select what area to work in.
For example here is a shot of the useable area. I have checked it off the list and expanded that area. It’s showing me tools or sites to validate usability. I went back and looked a a recent deployment of mine and ran through the checklist. This is a great tool to use or share with others. From simple things like SEO and robots.txt this list can cover some base questions.
