Why do you need SEO?

Building a strong site architecture and providing clear navigation will help search engines index your site quickly and easily. This will also, more importantly, provide visitors with a good experience of using your site and encourage repeat visits. It’s worth considering that Google is increasingly paying attention to user experience.

When it comes to how much traffic is driven by search engines to your website, the percentage is substantial, and perhaps the clearest indicator of the importance of SEO.

In 2014, Conductor suggested 64% of all web traffic comes from organic search, compared to 2% from social, 6% from paid search, 12% direct and 15% from other referral sources.

This tallies with our own data, with approximately 70-75% of SEW traffic coming from organic.

Of all organic traffic, in 2015 it was found that Google accounts for more than 90% of global organic search traffic. So obviously you need a strong presence on Google SERPs, but how strong?

Well, according to this study from Advanced Web Ranking (which I’ve trotted out before when discussing how to dominate Google) shows that on the first SERP, the top five results account for 67.60% of all clicks and the results from six to 10 account for only 3.73%.
