20 Myths About Google

Besides the last event that allowed 400 webmasters to have questions answered by people at Google, was published a slideshow of all the myths about Google and webmastering practices.

(It is a document from Google embedded into an iframe)

Here is the list of myths (I have added some extra myths taken from the event):

1. Myth: You must fill the keyword meta-tags.
2. Myth: Duplicate content penalizes a site
3. Myth: Mix of HTML and XHTML prevents verification by Webmaster Tools
4. Myth: It is important to submit in a thousand directories and search engines.
5. Myth: Participating in AdWords, AdSense or Analytics can promote a site / or penalize it.
6. Myth: If a keyword is important, it is important to repeat it in best places in most pages so they appear more relevant to major search engines.
7. Myth: Using an XML sitemap may downgrade a site
8. Myth: The PageRank is dead / or on the contrary it is all that matters.
9. Myth: It is vital to re-submit your site regularly
10. Myth: Once your page is at top in SERPs, do no touch anything on it.
11. Myth: Valid HTML or XHTML code provides a better ranking.
12. Myth: Using disallow in robots.txt will remove pages from the index.
13. Myth: The more there are links, the better it is.
14. Myth: All that matters is to put a website on top in the SERP (Note: this may be sufficient for webmasters)...
15. Myth: It is better than old URL return 404 errors for the new architecture will be discovered naturally.
16. Myth: Using "index, follow" in the meta "robots" is important.
17. Myth: Hosting a site on a shared IP does it to lose positions.
18. Myth: Domains with .edu or .gov extensions provide better baklinks.
19. Myth: An older domain helps a site in results.
