Search engine marketing (SEM) is related to SEO in that they both deal with digital marketing outreach on search engines like Google and Bing. However, SEO typically refers to internal, organic website optimization while search engine marketing is commonly known as advertising through a paid media budget. While SEO will help your website traffic increase through natural algorithmic means, SEM earns traffic through the process of purchasing ads on search engines. In the image to the left, you will see a search engine results page that is the result of typing the keyword “digital marketing” into Google. The top four results have a small green box that says “ad” underneath the primary title link. This signifies paid advertising, or search engine marketing, where a brand or business has paid Google to display their ads at the top of the page for that specific keyword.
Also, they launched a brand new Site Audit tool. They are still polishing it but it already gets some enthusiastic reviews. Unlike other tools, it does not just show you website errors and SEO issues and relevant recommendations. It lets you create your own issues and configurations for the site audit. I think it’s really great in the constantly changing environment of today’s SEO.
