BLEKKO
  • Turn Towards Blekko To
    Protect Yourself From Spams

2
  • From most trivial of matters to most important of
    issues, whenever we need some information we
    instantly turn towards internet search engines.
    Some of the major search engines like Google and
    Yahoo source content from other websites on the
    World Wide Web using complex algorithm equations
    that are highly susceptible to SEO and other
    manipulation. The results displayed, therefore,
    score low on quality despite being high on
    numbers. Blekko is a new-age consumer facing
    search engine which uses a high degree of human
    involvement along with algorithm equations to
    deliver high-quality, spam-free results from the
    most trusted of sites. 
  • The menace of spam has become widespread and
    despite the best effort of law enforcement
    agencies and IT companies, this scourge continues
    to grow at a much faster rate than before.

What is spam?
  • Spam is flooding the Internet with unsolicited
    messages about a host of products and services.
    It is a form of unsolicited advertising that is
    forced upon consumers by unscrupulous firms and
    companies. 
  • Spams can have some serious repercussions, as
    unsuspecting and gullible Internet users may
    believe in the commercial messages they receive
    of questionable products and quick get-rich
    schemes like Nigerian scams. 
  • Nigerian scam is a type of scam which was so
    christened because it originated in Nigeria. This
    scam, however, is no longer limited to Nigeria,
    having spread its tentacles to all parts of the
    world.

4
  • This type of scam usually involves the often
    played cock and bull story that a huge sum of
    money needs to be transferred outside the country
    and the person in question can get to keep a
    certain percentage of it, if he or she helped to
    move it out of the country.
  • This scam got a further boost with the advent of
    Internet and low operating cost of sending spams.
    E-mails were directly delivered in the victims
    inbox asking him/her to send certain amount as
    processing fee.
  • A huge number of people fell for it and still
    continue to do so in a fraud that often results
    in identity thefts and other online frauds.
  • Spams continue to flourish, as they cost very
    little to send. The burden of unsolicited
    advertising is borne by public and Internet
    service providers.
  • Blekko, since its inception, has declared an
    all-out war on spams and spammers. It has blocked
    hundreds of thousands of pages that made use of
    spamming in one way or the other.

What is spamdexing?
  • Spamdexing basically refers to spams that target
    Internet search engines. The word, in fact, is a
    combination of two words, which are spamming and
    indexing.
  • It refers to the unscrupulous practice of
    manipulating a web page to compel search engines
    to display them higher than other websites in
    response to a search query by the user.
  • It is a frustrating experience for users, as the
    results that are delivered to them are of low
    quality and usually irrelevant to the information
    desired.
  • Spammers usually make use of Black Hat search
    optimization techniques to influence their
    ranking.

What is Black Hat SEO technique and how does it
work?
  • A search engine results page (SERP) is the web
    page which the search engine returns in response
    to users queries. 
  • Black Hat SEO technique refers to the unethical
    practice indulged in by webmasters to trick the
    search engine to give a higher SERP ranking to
    their webpages.
  • One of the tricks used by these tricksters is
    called keyword stuffing or simply overstuffing.
  • Tricksters stuff their webpages with dozen or may
    be hundreds of keywords, so that they are easily
    picked up by search engines. Some even make use
    of text matching the pages background to make
    them invisible to users.

7
  • Another method used by fraudsters is to put
    irrelevant keywords on their pages to trick
    search engine. For example, the word game may
    be listed as keyword, whereas in real the website
    may be selling clothes for teenagers.
  • Unethical competitors also indulge in a trick
    called page stuffing. Website developers first
    create a page that appears high on SERP and then
    make an exact copy of it to ensure that both
    pages make it to the top.
  • It is an unscrupulous means of driving out
    competition by deliberately thwarting the
    attempts of other websites from scoring high on
    SERP.
  • Selling and framing of links is another favorite
    indulgence of people interested in Black Hat SEO
    techniques.

8
  • Majority of the search engines place high
    importance on the number of links that a website
    has to determine for its relevancy. Miscreants
    buy links from other sites to boost the rank of
    their sites.
  • A link farm is a collection of unholy nexus of
    Web pages that work on the principal of you
    scratch my back, I will scratch yours.
  • Web pages are interlinked to one another to
    increase each others ranking in the process,
    creating a highly frustrating search experience
    for end users.

Conclusion
  • Spam can be an effective tool for committing a
    variety of online frauds. They can be used to
    transmit viruses and other malicious software. 
  • Spammers use both human greed and their
    inexperience to perpetrate a variety of frauds
    like identity theft, phishing, and advance fee
    fraud, among others.
  • Blekko is a consumer facing search engine
    renowned for providing spam free results. It
    gives preference to quality over quantity, and
    delivers results only from the most trusted of
    sites. It does not solely rely on link-based
    authority preferring to involve human experience
    in delivering results.
