What are title tags? Title tags go in the header. They show up at the top of your browser. They can tell you many things about the page- where you are, what it’s for, etc.
They are also important in SEO friendly websites- in other words “Search Engine Friendly”. Some search engines place more importance on the title tag than others but you can start ranking better in Google by having effective title tags, according to SEOMoz.org
Here’s a tip: The farther to the left your keywords are, the more importance Google will place on it.
