It is the most important factor as per search engines because the title will be listed in the search results.
Title tag limit: try to keep the tag length less than 65 characters because anything more than 65 characters will cut off in the search result.
If you have already developed your site with more than 65 characters, evaluate if the keywords are covered with-in 65 characters or not. If any keywords are placed exceeding 65 characters then you need to fix it. You can have title tags more than 65 characters but make sure all the keywords are covered with-in 65 characters.
Title tag of each page should be related to the content of the page. Don’t ever use same title tag throughout the site.
Place most important keyword in the beginning of the tag.
Don’t just put the keywords in title tag but rather try to make it as a sentence. It will save your website from becoming a keyword spammer in Google algorithm. eg: Traffic Secret | Tips to generate instant traffic to the website. Text in bold are the keywords in a sentence format.
Pipe symbol “|” should be used to separate keywords or phrases.
Make sure that the keywords used in title tag are also present in the page content.
If you want to add company name or product name then add it at the end of the title. Don’t use it in the beginning of the tag. Because your target is not to get optimized with your company name but with the keywords which will increase the sale.
Make the title either controversy or solution to a problem or use a number because it will grab the attention of the visitors. Eg: 10 tips to generate traffic.
If you find difficultly in writing good titles then simply follow your competitors.
