For some reason it really grates me when I read people’s definition of PageRank being “the quantity and quality of inbound links”. To me, “quality” is fairly subjective and doesn’t really accurately describe it. I prefer to use “value” instead of “quality” since PR is just a numerical value. See, there’s that word again, value.

The PageRank value assigned to a URL is just the result of a numerical calculation. A higher value does not necessarily signify importance or quality. It just means that it has a large amount of PageRank being passed to it. This could be from one high value link, or multiple low value links. Google uses other means to determine relevance, quality, importance, spam, trust, etc.

What do you think?

I used the Google for Search app on my iphone tonight for the first time. I wanted to look up the names of the three tenors, so I tapped the voice icon and said “the three tenors”. Unfortunately it did not fully understand my accent and instead thought I was wanting to find “history tennis”. My family found it quite amusing when I had to repeat the search with a heavy American accent.

It would be really nice to have a settings option where I can read a passage of text so that it can better understand me. Then at least I wouldn’t have to have to break out the British fake southern American twang in public again.

Anyone else have problems? If so, do you have an accent?

Edit 6/15/2009:
Well it looks like they implemented some updates to their speech recognition so that it also understands British and Australian accents. Well done fellas!

For those of you who are into military humor, I had to repost these set of pictures, which came to me via email. I’m glad they still have a sense of humor with all the stuff they have to deal with. Thanks to all the service men and women keeping America safe.

[Update]
Well since this post was written, it seems that Google has decided to release something else which it’s calling TrustRank. The original TrustRank confusion was related to detecting and filtering spam, while the latest iteration is to do with calculating the “trust” of users bnased on the quality of annotations, reviews and tags they provide. These signals may be used to reorder the ranks of pages in the results.

Bill Slawski, as usual, has a great rundown of what it is from the Google Trust Rank patent filings

Original Post:
If you search Google for TrustRank you will find many blogs and forums talking about it and giving advice and theories about what you can do to alter it, but the fact of the matter is that it just simply does not exist.

At pubcon 2007 Suresh Babu interviewed Matt Cutts and asked him specifically to define TrustRank. Below is the video of that interview.

For those of you not able to watch the video, here’s a transcript where Matt Cutts talks about its origins and confusion between a Yahoo intern’s project and an antiphishing filter Google was developing.

What is trustrank? everybody’s curious about that. It’s kinda nice you asked because it’s good to have a chance to debunk this a little bit. So it turns out there was a summer intern who was at Yahoo and Jan Pedersen and some other people at Yahoo, and they wrote a paper about something called TrustRank; and what it does is it tries to treat reputation like it’s physical mass and see how it flows around on the web and what physical properties does trust have; and it’s really interesting stuff. But it’s completely separate from Google. So a couple of years ago at like the exact same time, Google was working on an antiphishing filter, and as part of that we needed to come up with a name for it and so they filed for a trademark, and I think they used the name TrustRank, so it was a really weird coincidence. Yahoo had a TrustRank project and we had this TrustRank trademark, and so everybody talks about TrustRank, TrustRank, TrustRank and yet if you go and ask five different SEOs you’ll have five different opinions and definitions about exactly what TrustRank is.

If you go to the US Patent and Trademark website and do a trademark search you’ll find this result:

If you go to the advanced published applications search page on US Patent and Trademark website and search for Trustrank you will find these results. Notice that none of them are filed by or Assigned to Google, although there are references to Yahoo’s link-based spam detection patent application.

So since Google has dropped the trademark, does not have any patent applications for it and Matt Cutts explained the confusion, I think I’d call this myth busted!

This message is a warning originally sent from the FBI:

For those of you who like to grill it up during the summer, here’s a safety announcement you should be aware of. Please put this information out to ALL personnel. For those of you who exchange your propane tanks, this is something you definitely need to be aware of, especially in light of the recent news of ‘Meth-labs’ in our area. Meth cooks are getting propane tanks from exchanges at Wal-Mart, Kroger, etc. and emptying them of the propane. Then, they are filling them with anhydrous ammonia (which they now have a recipe for by the way). After they are finished with them, they return them to the store. They are then refilled with propane and sent back for you and me to buy. Anhydrous ammonia is very corrosive and weakens the structure of the tank. It can be very dangerous when mixed with propane and hooked up to our grills, etc. You should inspect the propane tank for any blue or greenish residue around the valve areas. If it is present, refuse to purchase that tank. Check out the National Propane Gas Association Website for more details. They also have pictures.

Update (7/12/2008):
The NPGA has taken down this page from their site, so here’s an archived copy of that page:

I installed the new ga.js tracking script on this blog a few weeks ago and decided to take a look today to see if there are any reporting differences. Here’s what I found for the same time period:

Here’s a couple of screenshots of the top referring phrases. You can clearly see the differences.

Old:

New:

So as you can see, there’s quite a discrepancy, even for my site which doesn’t get a lot of traffic at all. I think I’m going to have to dig into this further and compare these stats with log files to see which is more accurate. I also want to make sure that the tracking codes really do appear on every page, to make sure that isn’t skewing the stats somewhat.

I’ll post back again when I find more info. If anyone else is doing a similar test, what are you finding?

Our CEO announced today that we came in first place for the Outstanding Product (less than 50 employees) category in the prestigious TechColumbus TopCAT Innovation Awards.

We were up against some tough competition from some local companies with very cool products, so it’s very exciting that ECNext was chosen.

In Jan 2007 ECNext also won the category for Outstanding Technology Team Under 50 People (press release).

TopCAT Awards have been run by TechColumbus for the past 10 years and is recognized as a premier event for technology companies in Central Ohio. The ceremony was held last night and drew over one thousand attendees compared to one hundred at its launch in 1997.

ECNext runs the fastest growing business information research website (manta.com), providing over 45 million worldwide company profiles and enables researchers to purchase online and download detailed market research, industry analysis reports and company news.

I’ve been a little preoccupied lately and tonight I decided to try out the new Google Analytics tracking code, which uses ga.js instead of urchin.js. To do this, I created a new profile, then added the new code in the footer.inc for this WordPress theme. This weekend I’ll be comparing results to see if there’s any differences in stats or reports.

Google could be heading down a slippery slope with Youtube and now knol. Their organic search results are meant to be unbiased and provide the most relevant results for any given query. In 2000 Google launched Google Adwords and we started seeing sponsored search results. That was ok, the ads were clearly marked and listed alongside the search results.

Google starts releasing additional services to diversify their revenue streams, like the Google search appliance, site targeting, radio and print ads.

At some point here, they suddenly realized that they have this great money making scheme called Google Adsense, but they only ever take a cut out of each ad because as a search engine, they’re designed to send traffic away. The next logical step here, from a money making point of view, is to take a larger percentage, or take the entire ad revenue. They can only do that if they become a content publisher. At that point there’s a huge conflict of interest in serving relevant, unbiased results and a serving up your own site, which makes money.

In Oct 2006 Google bought Youtube , then in May 2007 they launch Universal search to provide Youtube with more exposure in the search results.

Now with Google knol they want to extend publishing to textual content and run adsense. To ensure quality content and to keep the spammers at bay they will probably not offer a rev share either.

Since wikipedia has such a strong organic presence, that leaves 9 spots on page 1 for other reference material type sites. Enter Google knol and that reduces it to 8. Throw in Google’s diversification of search results and now for ecommerce queries, you may find that there’s only 1 spot left on page 1 for an informational article about a product.

So once knol builds critical mass, what could happen? Well obviously sites like about.com will loose rankings to knol. answers.com who already took a 28% traffic hit this year could face a double whammy by loosing rankings and having their keywords links in the results are replaced with knols.

What do you think might happen? Would you want to contribute an authoritative article to knol?

I used to work for an SEO agency in Pittsburgh and dealt with a number of interesting clients in a variety of industries, with large and small sites. There were a number of funny incidents that I encountered, which I’d like to recount here, although names will be withheld.

No Google Traffic
After taking on this client I gained access to their webtrends reports and it showed an astounding lack of Google organic traffic. I looked over the meta tags and page content and all seemed to be targeting the right set of keywords to some degree, although onpage could still use some improvement.

I knew they weren’t doing anything advanced like IP delivery so I used Firefox with the useragent switcher extension and confirmed that with my useragent set to googlebot, slurp or msnbot I could browse the site without any problems. After checking the robots.txt I found that googlebot had been disallowed! After asking the client’s developer why they decided to ban googlebot their response was: It was crawling the site too often and there were errors on some of the pages that were leading to open database connections and locking up the server.

Needless to say the developers got a quick lesson in why banning googlebot to mask their programming errors is not good business practice.
