Why the search result title might differ from the page's tag
If we’ve detected that a particular result has one of the above issues with its title, we may try to generate an improved title from anchors, on-page text, or other sources. However, sometimes even pages with well-formulated, concise, descriptive titles will end up with different titles in our search results to better indicate their relevance to the query. There’s a simple reason for this: the title tag as specified by a webmaster is limited to being static, fixed regardless of the query.
When we know the user’s query, we can often find alternative text from a page that better explains why that result is relevant. Using this alternative text as a title helps the user, and it also can help your site. Users are scanning for their query terms or other signs of relevance in the results, and a title that is tailored for the query can increase the chances that they will click through.
If you’re seeing your pages appear in the search results with modified titles, check whether your titles have one of the problems described above. If not, consider whether the alternate title is a better fit for the query. If you still think the original title would be better, let us know in our Webmaster Help Forum.
One of Google's suggestion seems to be the case in your site:
Brand your titles, but concisely. The title of your site’s home page is a reasonable place to include some additional information about your site—for instance, "ExampleSocialSite, a place for people to meet and mingle." But displaying that text in the title of every single page on your site hurts readability and will look particularly repetitive if several pages from your site are returned for the same query. In this case, consider including just your site name at the beginning or end of each page title, separated from the rest of the title with a delimiter such as a hyphen, colon, or pipe, like this:
ExampleSocialSite: Sign up for a new account.
The problem with your
title tags seems to be that your domain name "taskmasters" is at the end of a not-so-short title, so it gets truncated in the search engine results page and google does not like it. Consider making your title shorter or moving your site name to the front so that "Taskmasters" does appear in the result page.
