Keeping a handle on who is talking about your business or linking to your website can be an awfully large task. Blog search engines are available to help in some big ways though. Blog search engines aggregate blogs and web pages with rss feeds to index and make their content searchable in an organized fashion. For instance if I am looking for for information on search engine marketing, I can use Google as a resource to find my information or I can turn to a blog search engine to focus my search on only blogs. I can use their refinements such as the time frame the information was published in. I can also look for a particular post or an entire website about a certain topic. This can help the marketer or search engine optimizer keep tabs on what people are saying about a website. This can also help them keep up on who might be linking to a particular website by using blog search engines to search for that company, or other information. Blog search engines have become more and more sophisticated, and nowadays you can do a blog search on a variety of topics.
My favorite blog search engines are Technorati, Bloglines and Google Blog Search; each of these blog search engines let me search for a website name or use a refinement to track what people are saying and who is linking to our websites. All of them also let me bookmark those searches making it easy to check out the latest buzz on each of our websites or a particular topic I am interested in.
For example you can go to Technorati, type PlumberSurplus.com into their search box and see what posts or blogs have the word PlumberSurplus.com in them. This gives me quick, up to date information on what is going on in the blogosphere for whatever I might be searching for. More blog search engines are available in this list of blog search engines.
