SEO is unlike PPC ads because you cannot pay for a higher ranking. This means that SEO rankings come organically. In other words, to get ranked high with your site’s SEO, you must have lots of quality, relevant content.
There are several factors that go into your SEO. It is more than just keywords. Quality of content, as well as keywords, are important factors. You also need to factor in speed and crawlability for your SEO quality.
At first, site owners could just put a few buzzwords in specific areas of their content and a site would start ranking. However, algorithms are advancing and keeping relevant sites at the top of search results. As such, you need to put in more effort.
There are also multiple SEO categories, including local SEO, e-commerce SEO, and news/publishing SEO.
