Title tag
The title tag is that blue link that appears in Google search results, and also the name of each webpage that appears at the very top bit of your web browser. Google’s search bots read these tags first to start judging what your page is about and what keywords are most relevant, so they basically tell Google that your site is what users want to see when they look for certain keywords.
Meta Description tag
The description tag should be written in such way that it will show what information your website contains or what your website is about. Write short and clear sentences that will not confuse your visitors.
It is most important for the prospect visitor when looking at the search engine result page - this tag is often displayed there and helps you to distinguish your site from the others in the list.
Meta Keywords tag
Lately, the meta keyword tag has become the least important tag for the search engines and especially Google. However, it is an easy way to reinforce once again your most important keywords. We recommend its usage as I believe that it may help the SEO process, especially if you follow the rules mentioned below.
The keyword tags should contain between 4 and 10 keywords. They should be listed with commas and should correspond to the major search phrases you are targeting. Every word in this tag should appear somewhere in the body, or you might get penalized for irrelevance. No single word should appear more than twice, or it may be considered spam.
