Search engine advertising has become the place to advertise when doing business on the web. For those of you who don't know what it is, search engine advertising allows you to buy ads that show up in or near search results. Why has it become so popular? Because it works. It works because the ads are relevant to what the searcher is looking for. Try this link to do a search on Google and if you look on the right hand side, you'll see the Sponsored Links, those are the ads. Pretty much all the search engines have a similar system. If you want to advertise, you pick the search terms, keywords, or phrases and specify how much you want to spend on those specific terms. The more you spend, the higher you end up in the results.
Now in order to maximize the return on investment (ROI) when you are spending money on search engine ads, you have to know which ads are turning into conversions. You absolutely must have a way to track the results of your ads or you will be throwing money out the window and if you don't mind throwing money out the window, please let me know so I can stand outside your office.
There are two things to look at:
- The search phrase that the user searched on
- The ad copy (the wording of your ad)
A good web analytics package should give you everything you need to know about number 1, right down to how much revenue a particular phrase generated. So take that and subtract how much you spent on that phrase and you have your ROI. If it's a positive number, then you should keep advertising on that phrase. The most effective way to advertise on search engines and to make your tracking more accurate is to use
exact matches or at least phrase matches, not broad searches. By using exact matching, you can be much more precise in who your ad will reach, thus reducing your cost-per-click (CPC), and increasing your ROI. Furthermore, it makes your web analytics much more useful because you can see how effective your ads are based on exactly what your customers are searching for, rather than for what you
think they are searching for. If you want different variations, then add more phrases to your campaign. This can result in having a much larger list of phrases in your campaign, but why spend money advertising on "bike mountain" when what you really want is "mountain bike".
Number 2 is a bit harder because there is no specific answer, but what you can do is try out different ads over different time periods. For instance, in week 1, you try out ad copy 1, in week 2 you try out ad copy 2, then compare each weeks results. Or better yet, if your web analytics product can support it, you can append a special identifier to your ad link that your web analytics product can use to differentiate the two ads and then you can compare results over the same time period. And remember to take into account the number of
impressions each ad was given to do a real comparison. For instance, if ad 1 had 500 impressions and ad 2 had 1000 impressions, you should double the results of ad 1 to make a fair comparison. So if ad 1 had 50 clicks, 5 orders and $100 revenue, you should double those values to 100 clicks, 10 orders and $200 in revenue when comparing to ad 2. Google Adwords favors the ad that has the higher click-through-rate, not necessarily the one that has the highest ROI.
