For those that have been following the McDar Experiment thread, you may have seen an interesting statistic posted my McDar about a complete drop of rankings for the page in both Google and Yahoo. Post Here I for one find that result a little disturbing. In the past, a ban from one search engine - although a royal pain in the arse, isn't the end of the world because You still have the other 2 players to rely on. What if... Yahoo and Google were sharing data? (Again) I have no idea what this is about - I highly doubt that the sudden drop from both engines is a complete coinsidence though. Maybe the two engines happen to use a particular authority source to affect rankings and that changed somehow? Maybe they are sharing Data (I find this unlikely to be honest)... Maybe they are now *both* fucked? I have no idea, but lets see if we can determine whether or not is was simply a coinsidence (Again, pretty unlikely I'd say). Thoughts?
To make things easier... Here is the original post. The reason I posted it was that I have had my suspicions that Google had lost some sort of "pre-score" data for the experiment page and that was the reason for it dropping so far down in the serps. I never really thought anything before about Yahoo getting information from Google BUT thought that this was a very unusual event. It has been widely known the AOL uses Google's results with a little touch of there own algo added in. Could it be possible that Yahoo is doing something similar? A little further explaination of what I mean by "pre-score" data... Do you really think the when you search for a keyword, Google runs out an evaluates all of the internt (In the Blink of an eye) to return their results? OR Do they spider a page and store specific datapoints about it? -It is easy to do a keyword density and give "points" for the top % keywords. -Certainly, the predominant anchor text could be stored in the file. -The PR of the page... - etc. Certainly, there are many factors that can be pre-determined and stored about a page prior to any search. It would be ludicrous to think Google does not do this to some extent. BUT - what if some of this information was corrupted or dropped from Googles "pre-score databank"? Your page may end up in the Google boonies with all of the sandboxed pages that are there because they are still waiting to be "pre-scored" to begin with. Anyhow... The experiment page has been acting like some data was lost or dropped from Google and quite coincidently went "missing" from Yahoo at the exact same time. This was NOT easy to spot - I just happened to notice this! Is there anyone else who can find/see similar Yahoo/Google "coincidences" with any of your pages? Thanks, Caryl
As soon as I had seen Caryl's post the first time I checked Y against Google rankings for my site and several different sites I check. None of them showed this. On the other hand none had tanked liked the experiment page. Dave
not sure how well this tools works http://www.langreiter.com/exec/yahoo-vs-google.html but its lets you see the differences in both se searchs for any keyword
Actually, I have not seen them run "in parallel". I just saw that one instance where the page was dropped from both at the same time. Google now shows the page bouncing around the 400s but Yahoo has yet to return the page in it's serps. Going from position #1 to NOT FOUND is pretty wild! Caryl
yahoo IMO isnt much of a SE anymore, but rather is becoming a portal that offers tons of other things (such as launch, news, finance, etc)
