Actual 10 SEO myths for your web sites

In an article published searchengineland very interesting, listing 10 myths seo, worth taken into account. But in the end, no one has the truth in their hands, rather than Google itself.

These are the 10 myths SEO, as SEL:

1. Send the URL to search engines
2. Use Google Sitemaps
3. Upgrading the site frequently
4. Using Adwords affects positioning
5. Meet the Guidelines for Webmasters Google
6. Do not buy links
7. Using the tag H1
8. Using Meta Keywords repeating keywords
9. Content of 250 words
10. Optimizing the long tail “long tail” of search terms

Saying that a myth is something fictitious. In terms of SEO, it means that none of the above, used for positioning. Therefore, I disagree with most of the points, except for 1, 4 and 9. But the value of the listing is to incite debate, or at least a reflection of what is happening with the SEO.
