Search engine marketing (SEM) is a form of Internet marketing that involves the promotion of websites by increasing their visibility in search engine results pages (SERPs) primarily through paid advertising. SEM may incorporate search engine optimization (SEO), which adjusts or rewrites website content and site architecture to achieve a higher ranking in search engine results pages to enhance pay per click (PPC) listings
Methods and metrics
There are five categories of methods and metrics used to optimize websites through search engine optimization
- Keyword research and analysis involves three "steps": ensuring the site can be indexed in the search engines, finding the most relevant and popular keywords for the site and its products, and using those keywords on the site in a way that will generate and convert traffic
- Website saturation and popularity, or how much presence a website has on search engines, can be analyzed through the number of pages of the site that are indexed on search engines (saturation) and how many backlinks the site has (popularity). It requires pages to contain keywords people are looking for and ensure that they rank high enough in search engine rankings.
- Whois tools reveal the owners of various websites, and can provide valuable information relating to copyright and trademark issues.
- Google Mobile Friendly Website Checker: This test will analyze a URL and report if the page has a mobile-friendly design.
