Google title SEO question?

[ABC]

Dear Jia,

Google's generation of page titles and descriptions (or "snippets") is completely automated and takes into account both the content of a page as well as references to it that appear on the web. The goal of the snippet and title is to best represent and describe each result and explain how it relates to the user's query.

They use a number of different sources for this information, including descriptive information in the title and meta tags for each page. They also use publicly available information—for instance, anchor text or listings from the Open Directory Project (DMOZ)—or create rich snippets based on markup on the page.

While they can't manually change titles or snippets for individual sites, They are always working to make them as relevant as possible. You can help improve the quality of the title and snippet displayed for your pages by following the general guidelines below.

Create descriptive page titles
Create good meta descriptions
Prevent search engines from displaying DMOZ data in search results for your site.

Here are a few tips for managing your titles:

As explained above, make sure every page on your site has a title specified in the <title> tag. If you’ve got a large site and are concerned you may have forgotten a title somewhere, the HTML suggestions page in Webmaster Tools lists missing or potentially problematic <title> tags on your site.

Page titles should be descriptive and concise.

Avoid keyword stuffing

Avoid repeated or boilerplate titles.

Brand your titles, but concisely.

If they detected that a particular result has one of the above issues with its title, they 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. Once 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.

And in this case I can't see the title is informative to the user and its just the list of keyword in the title also in the webpage content.

Hope this help.
