Many SEO are looking for the perfect SEO formula to make a perfect optimized page. This is a mistake because Google doesn't want a perfectly optimized page. They want a most relevant content. I am not going to give a talk about what everyone already known. You have to somehow make your SEO imperfect! Yes, imperfection is the true beauty of SEO.

If your page title and ‘H' header have the exactly the same words, and the majority of your inbound and outbound links have the same anchor texts, you are looking very suspicious, suspicious enough to not ranking well. Google is quite ‘SEO-phobic'. Even if you put the same word in different combinations in your alt tag 3 times, you would immediately fall. For example, if you put ‘bookstore', ‘online bookstore', and ‘bookstore sale' in 3 different image alt tags, you would see the immediate fall in competitive keywords in your next Google page cache because ‘bookstore' appeared 3 times. To reduce the risk of ‘perfect SEO', you should mix things up a little bit and do thing ‘imperfectly' intentionally. You probably don't want to have more than 30% of your inbound links have the same anchor texts. If you already have most of your inbound links with the same text, you should build more links with different anchor texts and descriptions to dilute the ‘perfection'.

There are also some so-call ‘poison words' in your on-page link text, such as ‘add url', ‘links', ‘link partners'…These would indicate of low quality content or related to spam. The search engines are more likely to de-weight it.

Another bad SEO practice is, somehow I think it's too obvious, that people put the same word 3 times (or more) in the title. That's not right, not for title, nor description, nor the bold text. For example, you don't do ‘SEO Service SEO Company SEO Articles' in the title. You would still see such kind of repeated words in search results, that's because they have strong back links. These sites have already been de-weighted silently by Google. If you have the keyword repeat more than 3 times, oh my god, you are sending Google a message that ‘Yes, I am a Spammer. Catch me if you can'. One time for a keyword is perfect, 2 times with different form, such as ‘Online Bookstores in Bookstore Outlet' is acceptable. Notice there is a singular and a plural version?

Do you submit your new website to Google, Yahoo and other search engines? I wouldn't do that. Not that it's bad, just not worth it. As Google clearly saying in its official page that new website submissions would wait up to 6 weeks to be indexed. 6 weeks is quite a long time, and doesn't mean you would rank well after these 6 weeks. You still have a lot of optimization work needed to do after that. And some sites even don't link to sites with no PageRank. If you are not indexed, you don't get PageRank, then you don't get links from these sites. So, as soon as you brought a new domain, you build some content into it which doesn't need to be prefect. Then, you have to get your site indexed as soon as possible.
