Tips # 1 :
Include your most important keyword phrase in both your title and description tags ONE time. Your title tag should be around 8-10 words long, or shorter (Maximum of 75 characters, including spaces). Your description tag should be no more than a maximum of 150 characters, including spaces.
Tips # 2 :
Don’t capitalize the first letter of every word in the title or description, unless they’re proper nouns. The title and description should be very easy to read and just roll off your tongue.
Tips # 3 :

Tips # 4 :
Read all of your content, including titles and descriptions, out loud. If you stumble over words, so will your audience.
Rewrite until everything reads smoothly.
Tips # 5 :
Your title and description should be considered an “ad campaign” for your Web site, because that’s just what they are. Your page may be #4 in the rankings, but if you’ve taken time to create captivating title and description tags, you may have just as many click throughs as the #1 or #2 spots who haven’t done their homework.
