Use a Link Rel=Canonical Tag On The Homepage
Avoid Duplicate Subdomains & 301 Redirect Them To The Main Subdomain
Use Permanent Redirects From https: URLs To http: URLs IF They Don’t Require SSL
Use Robots.txt File To Prevent URLs From Being Crawled
Use ALT Attributes In Images
Avoid Use Of Rel=Nofollow Attributes On Links To “sculpt PageRank”
Return Response Codes Directly
Support If-Modified-Since/Last-Modified Conditional GETs
Periodically Check Your DNS Configuration
Conclusion
These are a few of the issues that were found that I commonly see or think are important. There were others, but they were relatively minor or subtle things like short titles, duplicate/missing meta descriptions, missing headers, and too many static resources per page.
Normally, I would have access to Web access log files and webmaster tools, which allows our software to check a lot more things.
I hope this gives you some ideas for things to check on your own site. And I hope that when you find something that you realize that even the search engines have their own technical SEO issues from time to time.
