What do you think is the most important element in SEO?

An important aspect of SEO is making your website easy for both users and search engine robots to understand. Although search engines have become increasingly sophisticated, they still can't see and understand a web page the same way a human can. SEO helps the engines figure out what each page is about, and how it may be useful for users.

• Online forms: Search engines aren't good at completing online forms (such as a login), and thus any content contained behind them may remain hidden.
• Duplicate pages: Websites using a CMS (Content Management System) often create duplicate versions of the same page; this is a major problem for search engines looking for completely original content.
• Blocked in the code: Errors in a website's crawling directives (robots.txt) may lead to blocking search engines entirely.
• Poor link structures: If a website's link structure isn't understandable to the search engines, they may not reach all of a website's content; or, if it is crawled, the minimally-exposed content may be deemed unimportant by the engine's end

· Non-text Content:

A Although the engines are getting better at reading a non-HTML text, content in rich media format is still difficult for search engines to parse. This includes text in Flash files, images, photos, video, audio, and plug-in content.

Getting the technical details of search engine-friendly web development correct is important, but once the basics are covered, you must also market your content. The engines by themselves have no formulas to gauge the quality of content on the web. Instead, search technology relies on the metrics of relevance and importance, and they measure those metrics by tracking what people do: what they discover, react, comment, and link to. So, you can't just build a perfect website and write great content; you also have to get that content shared and talked about.
