Although there are legitimate companies that help Web sites improve their rankings, according to Google’s page about Organic SEO , most such offers that arrive in e-mail messages are of little-to-no value. The search engine’s own Webmaster often gets Organic SEO marketing offers suggesting that Google doesn’t show up well in search results (which is quite unlikely). Google’s recommendation for Webmasters? Reserve the same skepticism for unsolicited e-mail about search engines as you do for burn fat at night diet pills or requests to help transfer funds from deposed dictators.
search engines want people to perform Organic SEO because it can help improve their search results. Search engines provide help in the form of guidelines, blog posts and videos to encourage specific Organic SEO techniques. However, there are some techniques that search engines deem "spam" or "black hat", which could result in your pages receiving a ranking penalty or, worse, being banned from the search engines entirely. With billions of web pages to sort through, looking only at ‘On-The-Page’ clues isn’t enough. More signals are needed to return the best pages for any particular search.
