Perhaps, no other marketing channel went through such radical transformation that the search engine optimization or SEO has witnessed in the recent past. While SEO was restricted to various questionable techniques like spamming, cramming with keywords, and manipulating the backend code during the initial years; Google eliminated those shady tactics pretty fast. Most of Google’s foundation was standardized during the mid-2000s, but its algorithm keeps evolving, and so did the rules of this game.
The gradual rise of online content: Google’s Panda update released in 2011 finally hit the last nail in the coffin and announced the death knell for keyword stuffing and spammy content. After Panda, the top web rankers were those with most relevant and quality content and made way for the inclusion of content marketing among the SEOs.
The death of link oriented schemes: Google maintains its very own definition of link schemes, and by the end of the 2000s, it removed almost all spam driven and black hat link building strategies. After it released the Penguin update in 2012, the business of building links matured into what it is these days.
The transformation of the local: In sharp contrast to the SEO of 2006, today’s local SEO is entirely a different ball game. The many subtle modifications and layout improvisations (local carousel and modern three pack layout) gave way to the Pigeon update in 2014. After this, Google tweaked its search algorithm appropriately, to improve the visibility of well-optimized websites in local searches. Mobile computing devices like tablets and smart-phones can be held responsible for the ever-increasing number of location-specific queries.
The rise of Knowledge Graph: The Knowledge Graph, coded by the engineers at Google, first made its public appearance in 2012, tries to provide the users with direct and concise answers for their questions; often in the format of a cleanly structured box.
