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:

  • sort by date or by relevance;
  • set the date range option (published past 1 hour, past 12 hours, etc or choose the date range);
  • support of advanced operators:
    • phrase control (exact match, forced word exclusion/ inclusion);
    • [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:http://www.domain.com] returns blogs linking to the given page.

Technorati

Technorati “indexes more than 1.5 million new blog posts in real time”:

“If Google is the Web’s reference library, Technorati is becoming its coffee house.” [source]

  • related tags support;
  • related tag cloud (updated in real time):

    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!

  • http://controversialmarketing.blogspot.com Sam Freedoms Internet Marketing Controversy Blog

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

    There is also a blog search engine called Twingly:
    http://www.twingly.com/

    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!

    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.

  • http://www.seobrighton.com JS

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

  • http://speedybands.com Stella

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

  • http://www.ftopics.com ftopics

    I use http://www.blogcatalog.com 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.

    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.
