Google's algorithm has changed several times since its birth in 1998. The internet has also changed drastically, yet some webmasters and SEO companies have not been so great at keeping up with current rules and regulations. People with an outdated understanding of how Google indexes sites, may be surprised to wake up one morning and realize that they've been blocked from the world's most popular search engine. You can prevent such a disaster by hiring a reputable SEO company like iBoost and by not using the following techniques.
Link Purchasing
Buying links is a big no-no. JC Penny found itself in hot water in 2011 when Google discovered they had hired an SEO company that acquired top rankings by purchasing links. Thousands of links that directed searchers to clothing items were found on pages that had absolutely nothing to do with shirts and dresses. Google does not like their users to be tricked, and spamming the internet with links to your website in places where no one is actively searching for your products is a great way to get Google to give you the boot.
