Google Algorithm Discriminates Against Bad Reviews

j_col writes "According to the official Google blog, Google has altered their PageRank algorithm to not give back linking points to bad reviews of websites belonging to online retailers, following the publication of a recent article in the New York Times describing one woman's experiences in being harassed by an online retailer she found via Google. The specific changes to the algorithm are of course a guarded secret. So considering that these changes are already live, how do we know how the algorithm determines a bad review from a good one, and whether or not innocent online retailers will be wrongly punished by having their rankings downgraded?"

    Uh, no. Google changed it so that websites of poorly reviewed retailers lose points, not the reviews themselves.

      To be exact, Google says they did not:
      • Block the particular offender, because it would leave all others like it intact
      • Use sentiment analysis, because it would discriminate any controversial subject
      • Begin to expose user reviews for merchants alongside their search results without affecting the search results.

      Instead they developed an "algorithmic solution which detects the merchant from the Times article along with hundreds of other merchants that, in our opinion, provide an extremely poor user experience."

      Before reading TFA my thought was that they could merely put zero weight on links in reviews claiming negative user experience. But Google's blog post says that was already being done: The review sites' links are rel=nofollow. "Ironically, some of the most reputable links to Decor My Eyes came from mainstream news websites such as the New York Times and Bloomberg."

      NY Times article states on page 3 that "Google is intimately familiar with the rage inspired by DecorMyEyes. If you type the company’s name in a Google Shopping search, you’ll see a collection of more than 300 reviews, many of them arias sung in the key of livid." My guess is that they have finally stopped ignoring this information for their search results.

      The tricky part is to keep the algorithm not suspect to manipulation by merchants who would write good reviews for themselves and bad for the competition.

Much of what I can't find is forum or mailing list archives, but of course, some of those come up very well and with high representation (e.g. Ubuntu Forums.)

      Of course, Pagerank has to be a secret for it to work, and as long as it's secret I have only very limited interest in trying to figure out how it works. I have discovered that my pages come up pretty often in web searches for related terms, often in the first ten results, and I achieved that by developing content that people want to view, by making my site google-friendly (for example redirecting all aliases to a single URL, google gets upset by duplicate content) and by making lots of links in my content to pages I found useful, which will tend to be pages which also have decent pagerank. Or in other words, I have good pagerank (apparently) simply by being a good internet citizen.

    .. I presume this means that the weighting would not be linear, but more like an exponential dropoff when reviews are numerous, time-disjoint, and all negative. I'm sure Google has done at least a sample analysis using their mountain of data. I think the biggest point made here is that (as a vendor) services to monitor your product/service will become increasingly important so you can reply to negative reviews and actively manage any trolls... whether this leads to more engagement or simply more astroturfing is yet to be seen.

Every bloody search returned crap because the SEO wankers had polluted the indices with junk -- you used to hit a page with 400K of keywords in the meta tag, and absolutely nothing to do with what you searched for.

      Google has always tried to find the best sites to retrieve, not the crap. By that very definition, Google was never un-biased.

    This is the fundamental problem with "crowdsourcing" reviews. Where the number of reviewers is large compared to the number of items being reviewed, as with movies, it works fine. Where the ratio is small, it doesn't. It's far too easy to game the system. There are automated tools for that.

    This problem has become worse since the October 27th change to Google, when Google Places/Maps results were merged into web search. This made "local" results much more prominent. Look at the first screen of Google search results for a local product or service. Most of what you see are Google Places results, maps, or ads. The organic results are so far down they don't matter.

    As a result, the "black hat" SEO companies are now aggressively targeting Google's places and maps system. "Convert Offline" is quite open about this, with their article Dominating Google Maps- The Most Effective Spam Ever And What You Can Learn From It" In some ways, Google Places is more vulnerable to attack than organic search. The number of web mentions of a local business tends to be small, so the amount of phony material that has to be generated to make a business look good is also small. Each mention carries a lot of weight.

    Google might lose this battle. Craigslist did. Back in 2008, Cory Doctorow wrote about "Spammers discuss breaking Craigslist verification system". It's become much worse since then. Personals were the first to go, and are now over 90% spam. Then Computer Services and Self Employment fell to the spammers. Jobs and Real Estate are under attack. Along the way, Gmail became a spam haven, especially after Jiffy Gmail Email Creator became widely used.
