Google's Site Ranking Secrets 309

Posted by samzenpus
from the more-google dept.
vivin writes "Ever wonder how Google's site ranking works? Wonder no more. Google recently filed United States Patent Application 20050071741 on March 31, 2005. This patent reveals a great deal of information about Google's site ranking algorithm and makes very good reading. For example, one of the criteria that they use is the number of years that your site has been registered. If your site has been registered for less than a year, then it counts against you. A site registered for a longer period of time means that the owner is probably serious about the site, and the site is probably legitimate. Google's Site Ranking algorithms reveal how hard they are making it for spam sites to get listed (on Google). This information will also make it easier for you to make sure that you get listed well in Google."

    'Google record the discovery of a link and link changes over time. The speed at which a site gains links and the link life span.' I fail to see how this would be helpful--if something's new and briefly popular, you only want to give it a high rank for a brief period and forget it once people stop linking. But if something's new and popular for a duration, you want to keep it well ranked.

      If you have a good site with valuable information, then, over time, news of it will get around, and you will keep getting new links over time.

      However, if you have gotten 1000 links at once, and for the next months noone else is linking to you - then you have probably bought the initial links, but nobody real considers the content worthy of attention.

    Could someone explain how other crap search engines are getting high rankings in Google search?

    Sometimes when I search for something specific, I get a bunch of useless links that have results of other "search engines" that invariably show something similar to "0 results for your search terms 'sheep+barn+slashbot+erotica'"

    How do these sites get on the first page of Google results?

      Yes, they're really annoying. They often have genuine looking summaries in Google's results, inticing you to click on them expecting to find useful information, but all you find is a page of links, often completely unrelated to your Google search. I wonder why Google hasn't got on top of them yet. All it would take is a second robot identifying itself as Internet Explorer slowly crawling the web looking for pages that give completely different results than the google spider.
      • I know, it seems so simple that Google just sends around another spider to reference their pages.

        Or, instead just change the browser tags of GoogleBot to random but human identifyable names to prevent sites from displaying only to googlebot.

        Instead of GoogleBot 2.0, it is "Google - Not Firefox - Bot 2.0" or "Internet Explorer via GBot v2". It would at least deter the sites that try to cheat google, and it would still identify to webmasters GoogleBot's traffic.

          It might be against the Robots Exclusion Standards [robotstxt.org] to deliberately fake your UserAgent header, but that's mostly so you can contact the robot's owner if it goes wrong and accidentally DOSes your site.

          I doubt severely anyone would mind if Google did an occasional, low-impact, slow, back-up crawl disguised as IE (presumably also from an IP address block not known to belong to Google), especially since GoogleBot has only

        This type of spam (showing a page to the crawler and another to the user) is called cloaking. Cloakers have anticipated this sort of move and can detect a search engine's crawler by not just the user agent but also the IP address range it comes from and other heuristics. In order to beat them, search engines would have to crawl from unpredictable IP addresses and behave like regular users.

        A while back I proposed a distributed approach like this in the Nutch mailing list [mail-archive.com]. The problem is that it would be hard to implement and it may not be worth the effort, since there are cheaper ways to fight spam.

      They are scaper sites.

      They get to the top through link spamming, 302 hijacks, "scaping" content from other sites, search engine optimisation etc etc etc.

      They are sites "made for adsense" as its called, whereby they exist for the sole purpose to be highly ranked in google and get ad clicks from people looking for something else. Effectively 'doorway' pages, which make a shitload of money, as people that land on such pages don't find what they really want, so click through on the ads in hopes of finding it there instead.

    They've thrown every technique they could have thought of into the patent purely as a defensive mechanism to prevent other major engines from patenting them. Some of the techniques are thrown in as defensive FUD to prevent newbies from using them.

      In order for a patent claim to be valid, a prototype must exist. Perhaps the most important word here is claim.

    Step 2: Go 5 years into past, buy domain names, set up sites with lots of soft porn images
    Step 3: Return to present, stopping off each year on the way to renew domains. Step 4: Sell to spammers etc.
    Step 5: Profit.

    I'm open to venture capitalists for investment in this one.

    • Step 1: Build Time Machine
      Step 2: Go back to 1994 and register Google.com (and Google.net and Google.org) before Google does.
      Step 3: Offer to sell the domains to them for 0.25% ownership of the company, and 0.5% of the stock to be issued in any "hypothetical" "future" IPO [yahoo.com]; this should be small enough they'll cough up without hesitating.
      Step 4: Pop back to 1977 and pick up 100 shares of Berkshire Hathaway while you're about it.
      Step 5: Profit!

      • Probably all that would do is cause them to pick a different name for the search engine. Unless you registered every possible domain, they could just choose from any that you hadn't registered yet.

        Besides, it seems like a lot of work when you already have a time machine. An easier solution would be:

        1. Find an event you can bet on with a huge payout.
        2. Go back in time and bet as much as you can.
        3. Go to step 2 until you're sick of money.

        I hate SEO with a passion (and I have to do it as part of my job), but you're right.

        The way I see it, SEO is a tool - nothing more, nothing less. It isn't inherently evil or inherently good - it's how you use it and what you use it for that matters.

        If you've got a good site on... i dunno... aardvark polishing for fun and profit, then you should rank highly on Google. If you don't rank well on Google, it's probably because your site is lacking one of fame, content or clean code. All of these are necessary for (or inevitable side-products of) a good site that does what people want.

        Conversely, a good site will probably have many inbound links, clean semantic markup, well-focused pages full of good content and so on. This is simply good site design (or, like the links, a side-effect of it), but it's also the very ethical end of the SEO spectrum.

        Now, you also get evil scumbag fuckwits-for-hire who specialise in link-farming, keyword stuffing, cloaking and other black-hat techniques, and sell their services to shitty pr0n or spam sites. This is spam - no doubt about it - but it only represents the black-hat side of SEO.

        The black-hat SEOers, it must be admitted, are the one which gets all the attention. They're the ones advertising like mad, making overblown claims, spamming search engines with crap listings and generally getting in people's faces. However, just because these people use SEO doesn't make SEO bad. Before SEO they were likely sending e-mail spams until that got too hard, but you don't unilaterally brand professionally-looking e-mails or people who sell mailing-list managers as evil, do you?

        As Google et al. get their acts in gear and revamp their algorithms, "SEO" is increasingly overlapping with "good site design" - this was always the intention, and even now "white-hat SEO" and "good site design" are pretty much synonymous.

        SEO isn't the problem - the problem is a combination of shithead black-hat SEOers, Search Engines inadequately assessing a page's worth and ill-educated types who shortsightedly blame the gun or bullet instead of the guy who fired it at them.

    I always suspected this... When we've started our business, we used the domain www.interakt.ro [interakt.ro] (we're from Romania). However, because we sell software tools mostly to the USA and Western Europe, we've decided to go to www.interaktonline.com [interaktonline.com].

    Instantly, our ranking went from number one (for "Dreamweaver Php" for example, we were number one there instead of Macromedia itself a long time), to page 10.
    Now, we're working hard to promote our site, we have links all over the place, but still our site don't get up again to page 1 (search for "dreamweaver extensions" - we have to pay to get our site in the first position). I even thought that they do this on purpose for us to continue to pay on Google Ads :D

    Probably they say it too in the patent, but the best ranking tool is to use the right "title" tag in your pages. It's invaluable how well this scores as compared to the page content.

It is not possible for google to know when you came back to the search engine from your site, or another one (unless you have a link in your site to google). It also impossible for google to know if you have a bookmark.

    Jeez, news for nerds, and the story was a badly edited blurb referencing a badly edited blog that didn't reference the patent application.

    Just look at the patent application yourself [uspto.gov].

    I haven't read the whole thing, but just having taken a quick look at it, I have to agree with the posters who said that Google purposefully tried to cover any conceivable technique to index and rank pages. The application discusses multiple implementations of the various techniques that could be used to rank a page. Therefore analysis of the patent application is probably of limited utility for those trying to game PageRank (which was certainly a factor that Google's very competent IP lawyers considered before prosecuting the patent).

    For those who are worried that Google is doing evil with this patent application, given the breadth of the patent and the fact that it discusses a plethora of techniques which Google may or may not be using, I will be surprised to see Google try to use this patent (or be able to use this patent) to push another search engine out of the market. More likely, I think, is that this will constitute prior art to enable Google to withstand challenges from other patent applicants for infringement. Of course, if you know anything about PageRank, you know that it was getting published in Scientific American long before Google was the dominant search engine. So this patent application is probably more to prevent allegations that Google infringed by adding on all the other checks and balances to the original PageRank technology to discourage spam sites.

At times I have been the 1st for "fun headlines," and at other times I have been around 10th.

    OK, so there aren't that many sites like mine, let alone sites that update daily over a period of years and include their entire archive on the site that grows daily. On the other hand, to my knowledge from doing searches on Google, I have very few site that link to mine, and I thought that counted highly with Google. So basically without trying to game the system, let alone advertise my site (other than incidentally in comments like this), I've been treated really well by Google.

    In my case, it must be the longevity issue coupled with the scarcity of sites like mine. It sure ain't the links to my site.

    ...that whole pigeon thing was a joke? I can't believe it. Maybe this filing just a way to divert our attention?
  • If your site has been registered for less than a year, then it counts against you.

    Interesting. This means that registering domain names as soon as I think of them, even though I tend to not get around to actually building the site for them for a while, is to my advantage (and not just for the sake of securing the name). I have one domain that I registered four years ago, but didn't have time to put anything more than a simple placeholder site on it until now. Now that I finally have it going, Google ma

    "As well as the number, quality and anchor text factors of a link."

    WFT kind of sentence is that!?

    I set up a link-exchange farm and make sure he's listed prominently.

    POOF he's branded a spammer.

    A stronger approach would be to find out who really owns the site.

    For example, let's search Google for "london hotels", a common search phrase. The first return is LondonNights.com [londonnights.com]. "Whois" returns "Worldview Ltd, 16 Marine Road West, Morecambe, LA3 1BS, Lancs, GREAT BRITAIN (UK)."

    That's a UK company, so we look it up at Companies House. [companieshouse.gov.uk], where we find "WORLDVIEW LIMITED, 16 MARINE ROAD WEST, MORECAMBE, LANCASHIRE LA3 1BS, Company No. 04588973". So we have a match on a registered company.

    We check further with Dun and Bradstreet [dnb.com], which has a worldwide database of companies. We find "WORLDVIEW LTD 16 MARINE RD WEST MORECAMBE , UK Type of Location: single"

    So they pass company validation, and we can get financial information about them.

    Now let's try a domain that just appeared in a spam: "fleagroups.com". "Whois" gives us "Flea Market Groups. 126 73rd Ave N., Coral Springs, Florida 34992. US" So we go to Sunbiz, the Florida State Division of Corporations [sunbiz.org], and search. No "Flea Market Groups" under fictitions names. No match on address under anything beginning with "Flea". No "Flea Market Groups" under corporations, and no "Flea Market *" address matches.

    Looking in Dun and Bradstreet, there are "Flea Market *" hits, but no exact match and no address match.

    So they fail company validation. Add to probable spammer list, drop search engine ranking.

    This is a reasonable test for any site that appears to be selling something.

    For example, one of the criteria that they use is the number of years that your site has been registered. If your site has been registered for less than a year, then it counts against you.

    So I get the following:

    Dear Webmaster

    I am interested in buying your domain vad1.com for $400.
    I'm only interested in the domain not in your content, so
    you can sell your domain and move your content to another domain.

    Google's Site Ranking algorithms reveal how hard they are making it for spam sites to get listed (on Google).

    And provides a list of techniques for spam sites to use that guarantee them positions on every search engine but Google (in fact, if you use these techniques it's illegal for other search engines to penalize you for them.

    This could be an especially evil technique for spammers.

    1. Set up search engine.
    2. Build some spam sites using search engine optimization techniques.
    3. Modify your search engine to penalize people using your optimization techniques.
    4. Get a patent.
    5. Profit, either from your increased search results in Google, or from suing Google for violating your patent.
