Search engine optimization (SEO) is a means of improving the results from a search engine so that they represent the closest matches and most reliable resources for the user's desired results.
As a contract SEO reviewer, working through a company like Leapforce, you can aid in this optimization. You start each evaluation task by judging a user's intent based on the keyword combinations provided and your own knowledge of popular culture in the user's locale. Then, you use a set of given guidelines to evaluate how particular search results match that user's intent.
Basic SEO, like link building, is fairly easy for most companies. But as more companies go global, competition has altered the way search engine algorithms find and display results for billions of daily searches, so only professionals with tech backgrounds really have the time and energy to perfect best SEO practices, like proper URL structure. These people really know how to best implement special tags on a website, and how to maximize tools like Google Image search to their advantage [sources: Hunt, Muller].
SEO reviewing can offer a steady income from home, but there are some risks. For one, an SEO reviewer must be willing to view potentially offensive material, such as pornography. And as a reviewer, you may be asked to check whether a given site contains malware or pornography, so you're putting your computer at risk as part of the job description.
