Google Lifeblood 

Like most people who have a Web site I check my site's ranking on Google SERPs (Search Engine Results Pages) from time to time. It's striking how much of a Website's life depends on Google. That's particularly true with smaller sites whose lifeblood is the traffic Google sends their way. But even bigger sites would suffer severely if their pages suddenly lost ranking in Google. Sure there are other search engines like Yahoo and MSN, but enough about those.

And so when a couple of days ago I noticed that my site's traffic had a noticeable drop in traffic, the first place I looked for diagnosis was Google. Sure enough, my site's pages where either non-existent or had dropped considerably in ranking. I know that compared to other sites, my traffic is but a drop in a proverbial bucket, but even so the realization of lost ranking made me concerned. I can only imagine how those people, whose living is tied to their traffic, may feel when Google starts to snub their sites. the results could be devastating.

Had I violated any one of Google's quality guidelines? Had I engaged in any activity that might have blacklisted my site? I was stumped. I hadn't made any design changes to the site that I could recall. I even tested my site for unintended search engine spamming using a couple of different online tools. One claimed I had hidden text on my pages. They were light-colored timestamps on a colored background. Just for insurance I changed them to a darker color. It also caught what it regarded as keyword stuffing. The culprit turned out to be whitespace characters ( ) with missing trailing semi-colons. So at least I got to fix this error on my site, and then I just moved on.

Today, inexplicably my site's ranking in Google SERPs seems to be back where it used to be. Could this have been the result of those minor changes? I don't think so. Most likely, the drop was due to some temporary event in Google's algorithm.

What's alarming is that Google is not just influential, but it's vital to so many. Where can one go to if they are unfairly treated? Who will listen? This is not a paid service, there are no SLAs (Service Level Agreements), contracts, or even tenuous promises. Mine is just a hobby site. Being present in Google is great, but I'd still be doing this even if my site wasn't included. I don't think my attitude would be the same if I were making a living off my site.

I can appreciate that Google has the enormous task of separating the good sites from the bad. But with that much power and reach, it is inevitable that many innocent sites will be inadvertently punished. Consider how things would be if there were only one powerful and unregulated credit agency with two marginal ones, instead of the three with equal standings today.

Homepage Hazards 

Sites, specially news-related or educational, usually cram their homepages with links to various sections and freshly updated pages. In that regards those homepages are portals into the rest of their respective sites where the real content resides.

That's all fine and good until they display links from those sections that the site maintains little control over. Forums, for example, are one these notorious areas trolled by spammers and jokers. The problem is that by nature they are supposed to be democratic. Pre-moderated forums generally suffer from anemic posts and little lively action. On the flip side, unmoderated or post-moderated forums spur real-time discussions, but invite nuisance posts.

This is depicted in the image grab from the homepage of devx.com, a development site frequented by programmers and, in this instance, linking to a prankster's or a spammer's post in one of their forums. The offending post was removed at some point, but the orphaned link remained on the homepage until it was pushed out by newer links.

Redirect Hacks and Phishing 

A few days ago in a blog entry I touched upon how search engine gamers had been able to use trusted domains and the 302 redirect trick to fool search engines into giving them higher rankings. That window of opportunity is all but closed now, but scammers still use the redirect hack to aid them in their phishing expeditions. They are able to foist their tricks on their unsuspecting victims using two main avenues consisting of spam emails and spam posts.

Suppose you receive an email with the following embedded URL:
  • http://www.ygdte682hdfajh1a.com/offer.htm?url=http://example.com


  • Would you click on this email? Most likely not, and nor will many others. You just can't tell who that weird URL belongs to, so you would skip over it. Now consider the following URLs:
  • http://froogle.google.com/%66%72%6F%6F%67%6C%65%5F%75%72%6C?%71=%68%74%74%70%3A%2F%2F%31%39%32%2E%30%2E%33%34%2E%31%36%36

  • http://www.aol.com/%72%65%64%69%72%2E%61%64%70?%5F%75%72%6C=%68%74%74%70%3A%2F%2F%31%39%32%2E%30%2E%33%34%2E%31%36%36

  • http://cgi1.ebay.com/aw-cgi/ebayISAPI.dll?RedirectEnter&loc=http://us.ebayobjects.com/2c;47586106;12593038;l?%68%74%74%70%3A%2F%2F%31%39%32%2E%30%2E%33%34%2E%31%36%36


  • Notice how the URLs indicate domains from Google, AOL, and eBay. Some people may still be skeptical about clicking, but others may not be so paranoid. After all those domains emanate from highly trusted sources. The URLs have some encrypted data, but we are all accustomed to seeing long URLs on various sites, and might attribute that to strong security.

    This is no trick. Those pages are indeed legitimate pages from well-known sites. But they are specially crafted pages to redirect users to other destinations. They were most likely designed to be used by their respective sites themselves and for other legitimate uses from the outside. But in this case they were hijacked to gain users' confidence prompting them to dutifully click on them. For these samples, users are safely redirected to example.com, but they could have been redirected to a wicked phishing site instead.

    Phishers also post the same types of links on various online boards, article sites, or other user submission areas, and they can gain users' trust just the same. Why wouldn't these links be automatically filtered by email servers or web sites? For the same reason average users see no threat in them. Filters might block or distort links they do not recognize, but many may give these links a free pass, convinced that they are from highly trusted sites and are therefore innocuous.

    Some well-known sites have started to take defensive measures to foil these types of redirect tricks, but abuse-ready redirect pages still abound. So the next time you come across these types of links in a spam email or on a site, think twice before clicking on them. They may just be the bait-and-switch kind.
