Organic search traffic is going to play a major role for almost all websites.
You can try to diversify, but the fact remains that any site with a ton of traffic gets a large chunk of it from search engines. After all, organic search traffic makes up over 60% of the traffic on the web.
And it’s not only the quantity, but the quality as well. For most niches, search traffic is the most engaged and highest converting.
In order to get large amounts of search traffic, you need backlinks.
Backlinks are arguably the most important ranking factor.
