Title, description, keywords
Meta information is used to provide additional information about HTML documents so that the search engine crawlers are able to index the information more accurately.
There are 3 important types of Meta tags as far as search engine optimization is concerned:
The Title tag is not a Meta tag. However title tags play a vital role in your site’s rankings. It is these words or phrase that appears in the title of your page in the hyperlink listings on the search engine results. We include the most relevant and specific keywords or key phrases in the title tag that best describe the contents of the page.
Meta description tag
This gives a short and concise summary of the content of your web page. The description appears in the SEs just below the title tag. I ensure that the meta description tag is brief but includes some of your top keywords. The words used must inspire the visitor to check your site out further. Each page must be customized so all your web pages will not have the same meta tag descriptions.
Meta keywords tag
Although not as relevant as the other tags mentioned above, the Meta keywords tag is still recognized by some SEs. We include a number of meta keywords for you that are relevant to the content of your web pages.
