Having a Search Engine Friendly Title Meta Tag specific to every web page on your website is extremely important and is widely used by the The Search Engine’s, most importantly Google. Make it between 5-10 words and put your best Keyword/Phrase at the beginning e.g. ‘Describe Page Content’.
The Description Meta Tag should be less than 150 characters in order to suit all Search Engines. Anything more than this will simply be missed out with some Search Engine’s. The “description” is what most Search Engine’s use to describe your site when listed in its results. Make sure it is ENTICING for potential customers. It should include at least 5 of your best keywords, words of advise... DO NOT just repeat all of them in your “meta tag description”.
