For better search engine ranking Meta information plays great role. There are only three important points we have to cover to get good rankings,
first one is Title which is very important because it represent your listing on the search engine. The second one is meta description comes after the title on the search results and last thing is meta keywords which is very useful to tell the search engine about your niche and services.
All these points are very important and if we care about these points then definitely Google will take care of our website.
