When I cashed a cheque for £17,100 that Google sent me last week, I knew how I was going to spend that extra £100 on the first rainy day. So on Monday, I dusted off the cobwebs of my Google Adwords account and set about creating my first PPC campaign since 12th April 2007.
I’d said to a few of my fellow code peers at a4uexpo and online that all my traffic is via SEO and I no longer take part in PPC as I haven’t seen any evidence to suggest it is beneficial. So I told them that I’d pick a random day and join in and then take an indepth look at the stats.
- I was to measure how many visitors I can buy for £100.
- How much time £100 will buy me.
- How much revenue that £100 investment would make me.
However, I also had to measure the benefit. And so I’ve collated traffic and commission figures for the day previous (Sunday 18th November) and one week back (Monday 12th November).
So here’s the backdrop. Sunday 18th November 2007 was Shop Codes highest traffic day ever, since launch. All this traffic was from SEO with Google contributing to over 1,000 of those visitors.
So to experiment on the following day was not probably the wisest choice as traffic may be on the increase and I may find the best is yet to come. And so it was. Yesterday Google (organic) delivered an extra 168 unique visitors, to make Monday 19th my highest ever.
I created one new campaign in Adwords that was to simply highlight that Shop Codes has 140 exclusive codes and I targeted keywords such as “voucher codes”, “discount codes”, “promotional codes” and “coupon codes”.
The minimum spend I was allowed to pay was £0.25. I set the daily budget to £300 and the maximum cost at £0.30.
As soon as the ad went live, it appeared in the top slot in the main part of the Google page. So within minutes I had maximum exposure.
Then soon after I could see that an affiliate network had started clicking on my advert. During my campaign an IP address of Affiliate Window appeared in my analytics.

The stats say that the first visit was at 15:10:53 for the search term “dixons discount codes”. The green url in the image is the url clicked on. The second url is the landing url. If the url is appended with “?clid” then that shows it is a paid-for link on Google.
The statistics summarise that this visitor stayed on my site for 2 hours 18 minutes and 28 seconds.
It shows they clicked on those adverts that were costing me £0.25 a click each, 26 times in those 138 minutes.
It shows that searches included “dixons discount codes”, “dixsons discount codes”, “shop codes” and “voucher codes”.
Some clicks were within seconds of each other, which suggests the visitor was using their browser back button and re-clicking.
After only a few hours, my campaign was at £95.91 and before closing it down completely I reduced the cost to £0.10 to see if the ad would show at all. It didn’t and so at 18:14 the last paid-for link was clicked and normal SEO traffic resumed.
It was not until this morning that I could assess the success or failure of paying for an extra 380 visitors. Was it a success?
Well, yes and no.
On Monday 19th November 2007 I received my highest days level of commission received this year.
Not surprising when I’ve joust bought 380 visitors but remember my organic traffic is on the up with Google organic sending an extra 250 visitors a day compared to just seven days ago.
OK, if I made the most money ever this year, why wasn’t it a success?
Well, the total commission was only £8 more than what I made on 12th November. That day there was no PPC.
I also made one fewer sale on Monday 19th than I did on Sunday 18th. That day there was no PPC.
So, £95 bought me only £8 worth of extra commission.
What else can I measure? Well, lets take a look at my RSS and newsletter subscriber figures. Did those 380 people contribute to an uplift in sign-ups? No, in the last two days I’ve had 5 new subscribers on both days.
So, I’ve summarised that I don’t receive any material gain from PPC. Yes, I’ll make more money (just) but I’d rather carry on making money without spending £95 a day. Or the £89 it would have been if a network wasn’t so keen on my site.
