• Be wary of SEO firms and web consultants or agencies that send you email out of the blue.

Amazingly, we get these spam emails too:

"Dear google.com,
I visited your website and noticed that you are not listed in most of the major search engines and directories..."

Reserve the same skepticism for unsolicited email about search engines as you do for "burn fat at night" diet pills or requests to help transfer funds from deposed dictators.

• No one can guarantee a #1 ranking on Google.

Beware of SEOs that claim to guarantee rankings, allege a "special relationship" with Google, or advertise a "priority submit" to Google. There is no priority submit for Google. In fact, the only way to submit a site to Google directly is through our Add URL page or by submitting a Sitemap and you can do this yourself at no cost whatsoever.

• Be careful if a company is secretive or won't clearly explain what they intend to do.

Ask for explanations if something is unclear. If an SEO creates deceptive or misleading content on your behalf, such as doorway pages or "throwaway" domains, your site could be removed entirely from Google's index. Ultimately, you are responsible for the actions of any companies you hire, so it's best to be sure you know exactly how they intend to "help" you. If an SEO has FTP access to your server, they should be willing to explain all the changes they are making to your site.
