Hi! I sow that my blog display Google search result including its name. For example my site name is "PC Tricks Tips!" if someone search "best chatting clients" Google shows "PC Tricks Tips!:best chatting clients" Why is that? Why Google always show ""PC Tricks Tips!:" before post title? Please look at this screen shot.

So you want your blog title to show up after the post title..... right ? Here is a URL for quick reference http://www.bloganol.com/2008/06/show-post-title-first-at-search-engines-results-page.html Hope this helps
After making changes to the title you will have to wait until google re-crawls the page or pages and updates the changes to the search results. It might be fairly fast and it might take a while depending on how frequent google visits your site and pages. If it is indeed a blogspot site try making a new post after applying your changes to the title and it is likely the new post will be indexed right away. Your old posts will take a while to be updated.
After indexing by google only it changes. Aftr clicking the link automatically it displays ur new tags.
