A title tag is the title of a web page that is shown above the meta description in search engines. It should be no more than 60-70 characters in length and should use strong keywords relating to your page content. I will give an example of what a title tag looks like below.
In the example above the search term I entered into Google was, "Organic SEO Blog". Google searched through websites that it thought was relevant to this search term and our blog was found to be the most relevant website in Ireland. Although the result was a combination of factors such as our relevance, URL, page content and description, the page title also plays a role in helping search engines to order a hierarchy of websites.
Our page title was, "SEO Blogs | Organic SEO Specialists Dublin, Ireland.” Search engines will scan the title to look for matching words that will help your site become relevant to the search term. In the example I have shown you the matching keywords are “Organic, SEO and Blog.” Even though they are not in that sequence that I had entered into Google search, Google still considered those keywords a match.
Google would advice you not to waste any of your title meta tag by using "stop words". These are words that are not actually picked up by search engines such as, and, it and are. So try to keep your title precise and use strong keywords relating to your page content.
The other reason why page titles are important is to indicate to users the content contained in a web page. In our page title it clearly indicates what that webpage is about, "SEO Blogs". Having a strong page title can help potential visitors to your website make the decision to click into your webpage.
I would recommend taking time to think about your page titles and try to have a balance between your keyword usage and a user friendly title. Doing this will significantly help your websites position in search engines like Google, Yahoo and Bing.
