I've often heard it mentioned that spending money with Google AdWords will help boost a site's rankings in the natural search results, i.e. AdWords somehow gives a benefit to SEO. Does Google AdWords help with SEO rankings? Short answer – No.
Whilst I've never believed it to be true, it is good never-the-less to hear it straight from Matt Cutts, who used to be the public face of Google:
Although this video makes the point that there is no connection between AdWords spend and SEO gain, there is a benefit to having more relevant visitors to your website. It is safe to assume that Google want relevant, high quality sites at the top of the search results, rather than those who are not specific to the search.
I'm sure conspiracy theorists will still claim that there is a connection between SEO and AdWords but, for the rest of us, hopefully that is one SEO myth that can now be put to bed.
