Personalization and SEO essentially have the same goal, to increase your revenue. However, they use very different tactics and methods to reach that goal.
SEO is one of the most important disciplines within online marketing, and it has been that for a long time.
High rankings, on the right search queries, can have a huge impact on revenue. Being able to climb one ranking can increase your Click Through Rate, which usually leads to an increase in revenue if you can convert the extra traffic.
The average CTR of page one, two and three in Google’s search results are 31.73%, 24.71%, and 17.66% – as expected, the further down the search results your page is located the fewer clicks you will receive. However, if you are able to move up a spot you will be able to increase your CTR significantly. Moving up just one spot in the search results can increase your CTR with 30.8%, of course depending on where in the search results you are located.
Google has 94.15% search engine market share, which means that Google has almost achieved a monopoly in internet search.
