A lot of website owners face this problem where they come to notice that the title tags are being rewritten or modified by Google itself. Sometimes, Google tends to ignore the title tags given by the webmaster altogether and picks some random text from the pages.

This usually happens when Google thinks that the title tags are too short or are not related to the content of the page for which they are given. This might happen if the webmaster has given repeated title tags for different pages. Of course, this is a bad practice.

In a very recent update, Google has brought some changes in the way it changes the titles of the SERPs. The general rule is to change the title whenever it is repetitive, missing altogether, too short or somehow stands inadequate.

Below are some of the common but standard points when Google will change the title tags of the webpages:

• Duplicate title tags are big no-no for Google. Webmasters should make sure that the title tags of different web pages on their websites have different title tags. Webmasters can check their Google Webmaster Tools account to make sure that they do not have a duplicate title tag or meta data.
• The standard minimum length for title tags is 65 characters. If the titles are shorter than this, Google is bound to change it for you. So, ideally, make sure you adhere to the standard length.
• More than 90 characters are also bad for title tags. Try to stay between 65 to 90 characters for optimized title tags.
• If no title tag is given to your webpages, Google will fill them for you automatically. If you are finding that you are giving the title tags but still Google is showing them as missing, make sure that the proper tagging is done in the HTML. Title tags should be inserted with these <title></title>.
• If the title tag does not match with the content of your webpage, Google will consider changing it for you and picking the relevant text from the page itself.
•  Sometimes, Google picks the description from the snippet of your Open Directory listing. If you want to override this behavior, you will need to insert this code in the header of your website: <meta name=”robots” content=”NOODP” />.
• Sometimes, webmasters have only a single text anchor text for all the incoming links. This may again harm the ranking of your page. Consider varying your anchor text for incoming links.
• Do not over optimize your web page for single text. This will make Google to change the title tag of your webpage and will also harm the overall ranking of your page.
• While it is not easy to solve the issue of Google rewriting your title tags, it is not impossible either. It just needs careful attention to the guidelines and also to the details that are standard for their procedure. Once you follow the general advice, you will the change in the scenario.
