Have you any idea that SEO myths are getting crazier each. Just how crazy? Read on...

Here are the most common organic-SEO myths as provided by Jill Whalen of Search Engine Land:

Myth 1: You should submit your URLs to search engines.

Myth 2: You need a Google Sitemap.

Myth 3: You need to update your site frequently.

Myth 4: PPC ads will help/hurt rankings.

Myth 5: Your site will be banned if you ignore Google's guidelines.

Myth 6: Your site will be banned if you buy links.

Myth 7: H1 (or any header tags) must be used for high rankings.

Myth 8: Words in your meta keyword tag have to be used on the page.

Myth 9: SEO copy must be 250 words in length.

Myth 10: You need to optimize for the long tail.

The bottom line is that before you go spreading a SEO notion - be it a myth or not - test it first. And do further testing. Bear in mind that some ideas may not always work. Or perhaps, the idea is connected with other SEO factors so be cautious about that.
