SEO Tip #1 - Use Keywords In Your Titles
This will be one of my little tid-bits of search engine optimization for the day. Use keywords in your titles. By doing so you increase the keyword density and tell search engines that this is important. Although, there are over 1,000 factors that can play into Googles algorithms, this is one small, but important thing you can do. You will also increase your chances of getting better site traffic and ad relevance if using AdSense or other keyword specific ad targeting systems.

Title tag is the only meta tag which is not ignored by Google and as well the most important one when doing on-page optimization. Choosing proper keywords especially in H1 tag is very important part of achieving higher SERP.

I can add that it is very important to use keyword in H2 and H3 tags. Most seo practitioners, just put bold and call it title which is wrong.
