Filter Words
Words like: is, this, that, am, were, the, etc. These words aren’t searched on when entered into a search engine. Having these words in a page title usually improves readability for your visitors, but if you could go without them leave them out. Every extra word in your page title (or H1 tags) decreases the relevancy of your main keywords as the title phrase gets longer. Filter Words are also known as Stop Words.
