When coding a site in HTML or PHP, meta data is really important. If you have read about SEO (Search Engine Optimization) then you would know that search engine like Google™ and Yahoo™ first read the meta data so adding it in your page makes your page even more easy for search engines to find.
But if you don't know how to write meta data then here is my Meta Tag Generator v1.0. Just enter the following data and hit Generate. Your code would be ready, just copy and paste the code between the <head></head> tags and you are done.
