Typically, you have threads about, how do I make my site better or what do I need to do to rank higher. Then people may discuss topics such as unique content, link building, etc. There is a thread at WebmasterWorld that takes the reverse approach. They discuss 25 things that may make a site appear to have poor signals of quality in the eyes of Google and other search engines. Here are the top 10 from the list:
- Reciprocal link request pages.
- Outdated copyright date or last modified date visible on the pages.
- Error pages that don't send 404 headers or send content regardless of the page requested/querystring entered.
- Massive numbers of incoming links from link farms.
- Dead/404ing links.
- High link churn.
- No published contact address, email address or phone number.
- A high bounce rate (surfers clicking back on their browser and selecting another search result).
- Too much duplicate content.
For the remaining 15, check out the thread.
This is one of those fun threads, I personally do not necessarily agree with everything in the thread, but I found it unique.
