Answer: Are you getting unsolicited emails claiming to improve your rankings? or “There are problems with your code” or “I can get you ranked number 1 in Google” or many other claims? Here are a couple of points taken from the Google Information site, you can read the whole article here – Google.
“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:
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.”
