Ideal number of keywords in an Ad Group

Is there a sweet spot range?

Is anyone was seeing Ad Groups with a large number of keywords getting penalized on Quality Score?

I have a few ad groups where every keyword has had the minimum bid raised, and these are mostly ad groups with many keywords.

I remember hearing in that past that about 80 keywords per ad group was generally a good number. Is there a certain threshold that you should avoid? I have a few ad groups with 1,000 keywords (many are long-tail terms with low impressions) and I was wondering how big is too big.

That has to be a myth.. I had Google raise my limit to 5000 keywords per ad group and had almost 100% of them active at 4 cents minimum bid..

I don't think penalties are due to the number of keywords in an ad group, per se, but the more keywords in an ad group.. the more likely that they're less relevant... which then, in turn, can potentially impact Quality Score.

If your grouped keywords are relevant, I would instead focus on performance reasons for keeping your ad groups lean. Despite my 5k keyword limit, Google has suggested no more than 2k for optimal UI performance.

yeah it takes a while for the ad group to load when you put in 5k.. I wouldn't put in that many if you plan to do a lot of maint.

Uh huh.

What's the weather like in la-la land?

Some of us advertise in countries other than the United States and in languages other than English smart ass..

the less keys the better, and having the keyword in the ad helps a lot. For me the 80/20 rule is strong in ppc. Keys in ad groups need to be related, tightly related.

I don't care if you were advertising in pig latin, the question was what is the ideal number of keywords in an adgroup. Responding with FIVE THOUSAND is just horrible information and a lie.

I'm not sure if you've ever even used adwords, but the max is 2,000 per adgroup and the odds of even 2,000 having bids of 4 cents is slim to none.

The answer to the original question is 15 to 25 total keywords. You can do a bit more or less, but that is the IDEAL number, (at least according to my rep.)

I expanded out my keywords in some adgroups to 3,000+ in a bid to pump the 'long tail'. I did have problems with CPC after this. I don't believe it was down to the number of terms in the agroup though, but rather Google exploiting the concept of the 'long tail'. As the long tail is supposed to be higher converting Google believe they should be (AND ARE) able to charge more for these terms. I have had it confirmed directly from a Google employee as I couldn’t understand why these terms were 500% more CPC than the most competitive terms for my industry. Beware of the long tail Google has made it a rort.

Actually, the max varies by advertiser - up to 5,000 per ad group and 1,000,000 keywords per account.

The answer to the original question is 15 to 25 total keywords.

That would require me having between 40,000 and 66,666 ad groups. Not exactly a scalable strategy.

I also have adgroups with more than 2,000 keywords. So, it varies.

Thanks for the reponses.

I think I'll be stuck with at least a few large ad groups for the long tail, but I'm going to shoot for 15-80 keywords for high-volume categories.
