Google announced they added a new filter that helps you find "specialized blogs" on any topic you can imagine.
Here is how it works. Go to Google, search for a topic, then click on the "blogs" filter on the left side (note: it might be hidden under a "more" link). Then when the page filters to blogs, click again on the left side, this time where it says "homepages." That filter will show the most important and relevant blogs on the search query you entered.
Here is a screen shot:
How is this useful? Well, for a searcher it is obvious, but what about an SEO? Finding blogs in a niche can sometimes be hard. Google has just made it so much easier. You can now find blogs in the aerospace engineering field or duck hunting field with ease. Form a relationship with those bloggers and garner links from them over time.
