Blog Search Engines : The Complete Overview

SMS Text

Blog search tools are numerous; most of them are pretty much useless (per my opinion). Here I am looking only at the most helpful and unique ones that I do recommend trying and that offer some great features.

Google Blog Search

Google Blog Search is a multi-language, multi-platform blog search engine maintaining the largest index and fastest update rate:

    • [inblogtitle:keyword] restricts search to blog titles;
    • [blogurl:keyword] restricts search to blog URLs;
    • [inpostauthor:”Author Name”] searches for posts written by a specified author;
    • [link:] returns blogs linking to the given page.

  • Hi , Thanks for the breakdown…it’s nice to have it layed out like that. I am still partial to google blog search..but this definitely is a great way to compare them. Thanks Smarty!

  • Excellent breakdown! A wonderful resource for insane hand-commenters 😉 seeking precious backlinks.

  • There is also a blog search engine called Twingly:

    It allows sorting of the results by Date, Inlinks and TwinglyRank (whatever that means). And filtering by language is also possible.

  • I use only Google Blog search, not only because it tracks down everything easily but also quickly and shows with multiple options. Technorati counts in all the splogs which link back to our blogs and generally their stats are always out of order!
    @ Bloglines – Its destructed right? 🙂

  • Cool, hadn’t heard of these before! May have to check some of them out!

  • Thanks for the good review of the 4 major blog searching engines, I am still partial to google blogsearch myself, but I do use Technorati occasionally.

  • Cool Post, I love Technorati… How do i get a better alexa rating thats the real questions 🙂

  • IMO, Google Blog Search is the best for blog search.. But technorati is also good for tech niche.

  • I tend to use Google Blog search a lot as well because it is returning so many pages!
    I think Technoarti is great as well though.

  • I use google blog alerts mostly. They are great!

  • as I experiment, what would you recommend should be a priority for learning the most about blog search engines? thanks for help for this rookie.

  • Hey, Kevin… Would you please explain, don’t think I understand your question – sorry 🙂

  • SM

    I definitely prefer google blogs. Their results are the best!

  • Thank you for your succint and very useful summary of blog search tools. Like a few others, I am partial to Google, but will give others a try.

  • Thanks. That info. is really well laid out, are they the only ones that you think are effective.

  • I’m thinking google blog looks better. It’s amazing how much is out there-oceans of info every which way. I’ve way tooo little time on any aat this point to have a valid opinion as to which blog is better for me.

  • Technoarti is probably the most comprehensive blog search tbh… although i’m a big fan of blog runner.

  • I love technorati but I also use google. These two make the best choice.

  • I use as blog search engine which is one of the best for me. Also I use google with some keywords to search blogs, few days ago I sow Google Blog Search and its simple bu I do not feel comfortable there.

  • Ann,

    Myself totally new to blog and seo. Your step step analysis is bit heavy for technically challenged people like me. Would it be possible that you use more simpler explanation?

    I loved the way you deciphered but would be keen to know more….

    Thank you so much for this effort.

    Justlearning about blogs. I really don’t understand them much. I would like to learn though. Whatgood are they and how can they help an online business.
    thank you so much.

  • Many use a blog content management system, because it’s one of the easiest way to create a website! Install and setup once and let the website owner update content from his end without too much hassle.

  • Thanks this is a really nice list

  • Is there a search engine comparison on blogs?

  • Thanks Ann, for this detailed report on blog search engines.

  • I agree with most of these tools being useless. Just use regular search.
