What goes into SEO?
To understand what SEO really means, why don't we break that sentence down and look at the parts:
Quality of traffic. You can attract all the visitors in the world, when they're approaching to your site because Google tells them you aren't a resource for Apple computers when really if you're a farmer selling pears, that is not quality traffic. Instead you want to attract visitors who are genuinely considering products that you offer.
Volume of traffic. Once you have the right people clicking through from those search engine pages (SERPs), more traffic is much better.
Organic results. Ads makeup a significant portion of many Search engines. Organic traffic is any traffic that you may have to pay for.
