Google Conversion Optimizer Results
Monday, October 8th, 2007Well, it’s been awhile since I first looked at conversion optimizer. I thought I would give you a brief update on my thoughts, and a report with some actual data. For another take on this tool from Google, take a look at the discussion on PPC Discussions, or this post from blogation.
So How Did Conversion Optimizer Work?
For the campaign I used it on, it worked well. Remember as I wrote initially, this is a campaign that had not been optimized thoroughly, although I had added some campaign negative keywords. I suppose the best test of the tool will be to put it up against my manual optimization skills. Perhaps I’ll try the technique advocated by Rose Sylvia of deleting all broad match terms, or try some other quick, formulaic approach. I think using a technique that can be applied quickly like that would create a more fair comparison, since the time needed to set up Google’s Conversion Optimizer is minimal.
I’m still going to reserve final judgment until further testing is completed, but in this case, Google’s tool did a fantastic job. Here are my numbers from the seven day period before using conversion optimizer, and the seven day period after turning it on. I am not using the day that I switched it, and I made no other changes to the ads or the landing page.
Just take a look at the before numbers:

So I was paying a little too much here. One of the ad groups is doing well, but the other is a little high on my conversion cost, and it’s the bigger one, of course. I decided I didn’t want to spend more than $70.00 per conversion, and that was what I ending up setting my Max CPA(Cost Per Acquisition) at. So how much did Google help me out?

Final Analysis
Not too bad. In the end, we have:
- 400 less clicks
- 106936 less impressions
- 22% higher CTR (click through rate)
- 4 cents higher average CPC
- $ 620.24 less spent. That represents $88.61 saved everyday.
- Slightly higher average position
- A little more than 42% lift in conversion rate
- A 35% reduction in cost per conversion.
- And even with less spend, we have 24 more conversions. That’s a little more than 3 extra sales every day.
So for this example, in this situation, Conversion Optimizer worked fairly well. It met my $70 CPA goal, and it saved me money while converting more traffic to sales. I can’t issue a blanket recommendation, but for anyone with unoptimized Adwords campaigns, or for the small business owner who needs to lower his or her cost per acquisition without paying for expensive software or consulting, Google Conversion Optimizer deserves a look.
