May Search Market Share Update: Crowd Sourcing Works!
Written by Jeremy Crane (contact - e-mail) -- June 20th, 2008 | Recommend ThisSee I told you we wouldn’t stop! As it turns out people are paying attention to this search share stuff. On Monday we released our May Search Share numbers. As a result of some conversations we were having with Danny Sullivan in parallel we sent over our “rules” we use to mine the search data. Danny threw these up on his post reviewing our data and one savvy reader very quickly identified an issue with our rules. So, long story short, we have fixed our Yahoo! rules (and also reevaluated all the other engine rules in the process). Here’s the updated data based on adjusted rules.
The bottom line is that we now have Yahoo! share between 18.5% and 19% depending on your personal opinion of Club Live search queries.

What changed … trendwise nothing changed
- Google market share rose to new heights on solid volume gains
- Yahoo! search share held just above 19% after a slide month-over-month.
- Windows Live Search market share declined ½ ppt or nearly a whole point depending on whether you count Club Live queries … guess you have to take the good with the bad
- Ask dipped slightly but managed to hold just above the 3% mark on relatively minimal volume declines
- AOL dropped to a new low hovering just above the 1% mark

What is Club Live?
What is the significance of it in the rules?
Also, how well do the news search pages do for the big three?

Is Yahoo!’s reduced share due to better search assist?
I recollect that Yahoo! launced Search Assist (a much more smarter way of suggesting keywords to “searchers”) around the October 2007 time frame. It is interesting to watch the search market share trend down from that time onwards (which was resonably steady at about 24% till then). A smarter suggestion will definitely reduce the number of queries.
What do you guys think about it?

Jeremy, % engine share of UV’s would be an interesting measure to examine ie. also want to answer how many more/less people using Yahoo Search, etc.

I always use live search and only use google as a last resort. I’m surprised more people don’t.

Could you turn on anti-aliasing on or just use a Mac when making these charts? I can’t even read the numbers… they’re so pixelated.

@Mark: I think you have a valid point. A good search suggestion definitely brings the number of queries down.

I guess the reason Yahoo is going down for the last two Quarters has more to do with Jerry Yang’s boneheaded ideas and direction, rather than any technical innovations.

yeah i agree alittle . i use google so i guess im alittle behind lol

I am very glad and surprised to see google at top. But yahoo is having a disappointing web share, I think yahoo can increase a little bit but not sure about msn. And this page is very good, i wish you good luck.
