  • It would be impossible to find any type of
    information on the World Wide Web (WWW) without a
    reliable search engine. Blekko is a new age
    search engine that makes it extremely easy to
    find the relevant information on the web.
  • There are billions of websites on the WWW. Search
    engines are the instruments that let us find
    quickly what we are looking for on the internet
    with minimum of hassle or wastage of time.
  • Each website has a particular and unique URL
    associated with it. This URL, in fact is the
    websites address. Like mentioned above, there
    are billions of websites on WWW.
  • It would rather be impossible for an average
    human brain to memorize the address of few dozens
    of them. This is where the search engine comes
    into play. It would be next to impossible to find
    specific information on the net without the help
    of a quality search engine.
  • In the following section, we shall look at how a
    search engine works and see for ourselves how a
    judicious selection of search engine can help
    users get what they want without exposing them to
    any online fraud or cheating.

How Search Engines Work?
  • There are basically three types of search
    engines. Look at them one by one and find out
    which can serve your purpose the best.
  • Crawler Based Search Engine
  • Crawler based search engines use special software
    to visit different websites. They scrutinize the
    content of the website, read its meta tags, and
    find information about the links coming and going
    from the website.
  • Meta tags are special Hyper Text Markup Language
    (HTML) tag that provide some very important
    information to the crawler. It tells the crawler
    what the page is all about, who created it, how
    often is it updated, and
  • which keywords represent the content
  • of the page, among others.

4
  • Meta tags are very important, as a great amount
    of emphasis is laid on them by search engine
    crawlers while indexing the websites.
  • These automated programs called crawlers after
    arming themselves with all the relevant
    information about websites return to the central
    depositary where the data is indexed.
  • The crawler at regular intervals returns to the
    website to find out if the website has undergone
    any upgradation or whether any changes have been
    made to it.
  • Here, we are talking about indexing. This means
    that whenever any query is typed into the search
    box of the search engine, it is the indexes
    created by the crawlers that are tapped into to
    find the specific information queried by the
    user.
  • In fact, this is the reason why hundreds of
    thousands of results are displayed by the search
    engine in a fraction of a second. They do not
    have to search the web, but their own indexed
    databases for the information.

5
  • There is, however, one potential downfall to it.
    We sometimes get dead links displayed on the
    result pages of some major search engines. This
    happens because the page may have been active
    when it was indexed and became invalid after the
    indexing procedure was complete.
  • Human Based Search Engine
  • Human based search engines rely completely on
    human expertise and submission for their
    cataloging and indexing. Only the information
    submitted by net users is put into the index.
  • Hybrid Search Engine
  • These are search engines that are an amalgamation
    of both sophisticated algorithm and human
    expertise.
  • They are the best, as they seem to combine
  • the best of both worlds for quick and relevant
  • results.

How Blekko works?
  • It is a new age sophisticated search engine that
    relies on human expertise as much as it does on
    its sophisticated algorithms to get the best and
    most relevant results for its users.
  • This new-age search engine makes use of end
    users' experience and volunteers expertise to
    categorize the web in an effort to offer
    comprehensive protection to its users from spams,
    malwares, and other scams perpetrated on net by
    fraudsters.

  • "We're trying to use the Wikipedia approach to
    categorize the Web, bringing large-scale human
    curation to search not on a search-by-search
    basis but a category-by-category basis," Mike
    Markson, Blekko's vice president of marketing and
    one of the company's cofounders, told in an
    interview to a major magazine.
  • Websites are selected and organized around a
    single topic. This effectively narrows down the
    search, thereby presenting the users with only
    the most trusted and reliable websites.

8
Conclusion
  • Using a search engine that prefers quantity over
    quality could be an extremely frustrating
    experience for an internet search engine user.
  • Time is a precious commodity and no end user
    wants to wade through dozens of dysfunctional,
    dead, harmful, or irrelevant links to get what he
    wants.
  • Spamdexing is on the rise and every day we hear
    stories about innocent and unsuspecting users
    falling prey to evil designs of online
    charlatans. Blekko is a search engine that makes
    use of both algorithms and human experience to
    deliver spam free results.
