Google Blog Search FAQ

  1. What is Blog Search?Blog Search is Google search technology focused on blogs. Google
    is a strong believer in the self-publishing phenomenon represented
    by blogging, and we hope Blog Search will help our users to explore
    the blogging universe more effectively, and perhaps inspire many
    to join the revolution themselves. Whether you’re looking for Harry
    Potter reviews, political commentary, summer salad recipes or anything
    else, Blog Search enables you to find out what people are saying
    on any subject of your choice. 

    Your results include all blogs, not just those published through
    Blogger; our blog index is continually updated, so you’ll always
    get the most accurate and up-to-date results; and you can search
    not just for blogs written in English, but in French, Italian, German,
    Spanish, Chinese, Korean, Japanese, Brazilian Portuguese and other
    languages as well.

  2. How do I find Blog Search?There are a few different ways you can get to Blog Search:

    It’s the same search in each place, no matter how you get to it.
    The Navbar, however, provides two buttons: one to search the blog
    you are currently viewing, and one to search all blogs.

  3. How do I use Blog Search?Just type the word(s) you want to search for in the text box and
    click “Search.” That’s all there is to it!If you want more control over your search, click the “Advanced Search” link
    to the right of the search button. There you’ll find options to specify
    titles, authors, languages and more. Once you get your search results,
    there will be an additional link that allows you to switch between
    displaying the results with either the most relevant or recent results
    at the top.

    In the Blogger version of the interface, there is an extra “use
    search options” link beneath the search box. This will show a few
    of the most common advanced options, such as a specific blog or a
    date range to search within.

  4. Which blogs are included in Blog

    The goal of Blog Search is to include every blog that publishes
    a site feed (either RSS or Atom). It is not restricted to Blogger
    blogs, or blogs from any other service.

  5. How do I get my blog listed?If your blog publishes a site feed in any format and automatically
    pings an updating service (such as,
    we should be able to find and list it. Also, we will soon be providing
    a form that you can use to manually add your blog to our index, in
    case we haven’t picked it up automatically. Stay tuned for more information
    on this.
  6. Why aren’t my oldest posts listed?Since Blog Search indexes blogs by their site feeds, it will only
    include items that have been posted since it started indexing a given
    blog. For most blogs, that will be around June 2005, or the time
    at which you submitted your blog for inclusion. We are working on
    ways to include older posts as well.
  7. What if I don’t want to be listed?If you do not publish a site feed for your blog, it will not be
    included in Blog Search. However, if you previously published a site
    feed that was included, the old posts will remain in the index, even
    though new ones are not added. 

    Blog Search will also respect robots.txt files and NOINDEX,
    meta tags, as
    described here

  8. How does Blog Search work?Blog Search indexes blogs by their site feeds, which will be checked
    frequently for new content. This means that Blog Search results for
    a given blog will update with new content much faster than standard
    web searches. Also, because of the structured data within site feeds,
    it is possible to find precise posts and date ranges with much greater
  9. Can I search for entire blogs or individual
    You can use Blog Search to find either specific posts or entire
    blogs. The main search results always return links to posts. However,
    when there are entire blogs that seem to be a good match for your
    query, these will appear in a short list just above the main search
  10. Can I subscribe to search results?Yes. At the bottom of each page of search results you can find several
    links, offering the top 10 or 100 results as either Atom or RSS feeds.
    Just grab the links from here and subscribe to them in the news aggregator
    of your choice and you will get updates whenever new posts are made
    that match your query.(If you’ve never subscribed to feeds before, check out Blogger
    and AtomEnabled for
    more information, along with links to various programs
    you can use to subscribe
  11. What search operators are supported?All of the standard Google
    Search operators are supported in Blog Search. These include:

    • link:
    • site:
    • intitle:

    Additionally, Blog Search supports the following new operators of
    its own:

    • inblogtitle:
    • inposttitle:
    • inpostauthor:
    • blogurl:

    For example, a search such as [mandolin inpostauthor:Graham]
    will show you posts about mandolins written by people named Graham.
    Note that you can also use the Advanced Search option to achieve
    the same effect.

  12. Can I find blogs in specific languages?Yes, you can restrict results to any of 35 specific languages by
    using the Advanced Search options. Just check the boxes next to the
    languages you want to include. By default, results include blogs
    written in all languages.
  13. Does Blog Search support SafeSearch

    Yes, SafeSearch can
    be used to filter out adult sites, just like in Google Search.
