My AdWords Spending for 2010

Posted by Matt on Thu, Feb 10 2011

This post is a follow up to How Much Money I Made From Side Projects In 2010 from earlier in the week. In that post I talked about how much revenue was generated from one of my side projects. Clearly those numbers are worthless without looking at how much it cost to generate that revenue. Let's take a look at that.

AdWords

Although I tried some other ad platforms as well (mentioned later), I spent the most with the Google AdWords network. In the HN thread for the previous post I estimated $5k. Turns out I was pretty close. Here's a month by month break down.

Month Clicks Impressions CTR Avg. CPC Cost Cost / conv. Conv. rate
1/1/2010 334 21100 1.58% $0.18 $60.72 $1.17 15.57%
3/1/2010 126 12289 1.03% $0.18 $22.60 $2.26 7.94%
4/1/2010 428 42810 1.00% $0.22 $93.83 $1.95 11.21%
7/1/2010 369 22621 1.63% $0.22 $80.88 $2.45 8.94%
8/1/2010 4195 158202 2.65% $0.27 $1,116.61 $1.99 13.37%
9/1/2010 5126 193727 2.65% $0.28 $1,444.94 $2.14 13.17%
10/1/2010 2494 123450 2.02% $0.27 $671.19 $2.09 12.87%
11/1/2010 1166 71018 1.64% $0.26 $304.34 $1.98 13.21%
12/1/2010 1154 67267 1.72% $0.26 $298.40 $1.94 13.34%
Total 15876 921912 1.72% $0.27 $4,215.75 $2.10 12.65%

I was about $800 over on my estimate.

How I Read These Numbers

I'm far from an AdWords expert and I don't pay nearly enough attention to my campaigns as I should. The number I generally look at the most is cost per conversion ("Cost / conv" above). 

In 2010 I paid $2.10 for every user that signed up for a free account. Since paid accounts at $20 to be profitable I would need to convert free users to pay users at a rate slightly better then 10% (10.5% to be exact).

Granted some of these users may renew which means in the long term I can afford to do less then 10% and still come out ahead.

Free To Paid

I didn't always, but for at least the last year I started keeping track of how new users came to the site. This allows me to check how well various customer acquisition methods are working at converting to paid accounts.

This is just looking at users that came in from AdWords.

Month Signups
Paid Conversion Rate
2010-01 57 11 19.3%
2010-03 10 1 10%
2010-04 50 3 6%
2010-07 31 6 19.35%
2010-08 561 102 18.18%
2010-09 677 119 17.58%
2010-10 318 56 17.61%
2010-11 150 20 13.33%
2010-12 145 13 8.97%
Total 1999 331 16.56%

What This Means

That I'm an idiot who should be spending more on AdWords.

I spent $4215 and generated revenue of $6620. That's +$2405 (not including PayPal's cut). My free to paid conversion rate is 16.5% - well above the 10% break even point.

Those Who Don't Learn From History...

...something something. Last year I came to the same conclusion. I'm not spending enough on AdWords.

Last year I spent $762 on AdWords and made $1720 for a difference of +$958.

Although I increased my AdWords spending 5.5x my revenue only increased  3.8x. This seems to indicate that my return will diminish as I throw more money at AdWords. There still seems to be room to push it higher though and still do well.

Facebook Ads

I also gave Facebook Ads a try last year. I spent $120 on ads over a 5 day period in September. No one even signed up for a free account. I killed that campaign pretty quickly. I'm not saying Facebooks Ads can't work, but I clearly needed to change my approach. I haven't revisited this, but may at some point.

Coming Up

In my last post I showed that I made $30k in new orders. If only $6600 came from AdWords, where did the other $23.4k come from? I'll take a look at that in an upcoming post so, make sure to sign up for my feed or follow me on twitter.

I'd imagine word of mouth is a pretty big factor, especially with teachers. The younger generation of teachers (the tech savvy ones) like to share new tools and things they've found that help make their job easier. You might even make more incentives for referral purchases to up your subscription rates a bit.

Thank you Matt for sharing. Very interesting and useful information.

I agree with Brendon on this. Teachers talk about their tools and techniques with other teachers, they talk about the materials they use with parents. I don't think facebook ads work. To me they are meaningless. They all look scams to me, even the known brand ones too. Creating a fan page and keeping it exciting with updates would be lot better than the ads in facebook, in my opinion. Then of course, there is twitter, a totally different animal...
