How long should I make my web page's Title, Description, & Keywords Meta Tag?

Different Search Engines will read different amounts of characters in your web page's Title Description and Keywords Meta Tag. As for your "Title", the Search Engines will read between 60 and 150 characters. The average number of characters in your Title that are read by the Search Engines is 70. I always tell everyone to write their Title using only 70 characters. Once you write your 70 character Title continue writing it until you fill up the remaining 80 characters for Search Engines that can read 150 characters in your Title. When it comes to writing your web page's "Description" the Search Engines will read anywhere from 150 to 250 characters. That is why I recommend to people that they focus on writing a good compelling Description for their web page within the first 150 characters of their Description Tag and then continue writing a good compelling Description until you have used up the remaining 100 characters that some Search Engines will read. Many of the Search Engines on the internet never read a web pages Keyword Meta Tag. As for the few Search Engines that still pay attention to your Keywords Meta Tag, the largest number of keywords they will read is 15 words.
