A search engine optimization (SEO) analysis is a report that details how a website owner can improve his or her ranking on popular search engines. The analysis commonly looks for and evaluates duplicate content, inbound links to the website, and uniform resource locator (URL) structure. This report is normally generated by a website, and there is no need to download a software program. Some SEO anaylsis websites even tell the webmaster how to fix the problems it finds. For example, if the website uses Flash® in a way that hinders search engine crawlers, an SEO analysis might detail how to best work around the problem.
