London SEO services and SEO services throughout the country have increased dramatically over the last few years. The origins of SEO are not clearly identified as is the case with many internet-based advancements, but it is thought to have first gained momentum as a concept in around 1991 as a result of the creation and further evolution of Google as a search engine.
During the early 1990’s more and more people were using the internet both as a means of research and also to find companies whose services and products that they were interested in. The problem with the early search results was that the quality of those results could not always be guaranteed meaning that individuals searching for a particular item would not necessarily get the best results on the first page of the search results. This resulted in websites being stuffed with the keywords that people were using in their searches and in some cases, this made the written content on some website impossible to read and gave a really poor user experience. This practice along with some others from the time became listed as black hat SEO practices and are no longer accepted by Google.
By 1998 the co-founders of Google had established PageRank which was a sophisticated algorithm that was designed to help rank the search results best on the keywords but also based on the quality of the website. This is probably where the birth of Search Engine Optimisation as we know it occurred. By the turn of 2000 Google had positioned themselves at the forefront and even started to provide guidelines that web designs and SEO companies could follow to ensure that they were using what was now known as white hat SEO rather than the previous now frowned upon black hat SEO practices. The guidelines explained how the white hat SEO worked within the parameters of the Google algorithms and enabled websites to rank higher in the search engine results.
Since the early 2000s there have been many changes to the Google algorithm and along with this comes a tweak to the way that SEO practises take place. The notable change came with the introduction of the Florida update in 2003, the launch of Google Analytics in 2005, the Caffeine algorithm change in 2009, Panda in 2011, Penguin in 2012 and in 2015 the mobile update. As the algorithm is adjusted, we will see more changes to the way that we conduct SEO on sites.
