hello friends, here you can get information about most common seo mistakes. Visit this link to find some SEO mistakes Thanks
The information contained in the article should help newbies to avoid these mistakes. Another thing to note is that, you should optimize fairly between humans and bots. Learn what bots are eating and what humans are appreciating. I usually close blog sites promptly upon knowing that the content provided is not mainly for humans but for bots.
Essentially, the biggest SEO mistakes are doing something that pisses off google, which includes, overpinging your site, getting an <h1> link from a bad neighborhood, or building too many links too quickly.
It is sometimes difficult to really know the answer to a question like this. There is so much conflicting information out and about. For example I've read that the keyword tag should not have more than 8 keywords yet I've seen sites with as many as 30+ keywords ranking on the first page. I think a lot depends on the competition - take a good look at the top 10 pages ranking for your keyword and follow their lead.
