To understand why
SEO (search engine optimization) is important, you need to know what
SEO does for a website.
If you needed to hire a new manager for your office you would let people know about the opening by advertising. An ad in the paper would include the positions’ title, job description, and how to contact you. It might also state how not to contact you (i.e., no phone calls).
Meta data and other codes provide similar information to robots including titles, descriptions, and instructions on how and what to read on a webpage.
A robot is what search engines (and other information gathering companies) use to find your site, analyze it, and then decide what to do with it (ignore it, ban it, or index it).
Think of
SEO as advertising your site to search engines. If robots do not know about you, like what they see, or cannot understand what you are saying, you will not get search engine “air time.”
