So, one of your campaigns is doing well: you have a few sales, and wonder what’s your next step. Can you take it to the next level? Make it more profitable? Let’s talk about expansion, as Matt Levenhagen calls it.
If you are using the Adwords Editor, you can view your stats for that campaign and even search for specific parameters. Do you see lots of keywords that have no impressions? Remove them. Do you have keywords with lots of impressions, but very few clicks? Delete those too, since they’ll pull down your CTR, unless they are making sales. If they are making sales, you need to figure out why your CTR is so low, and take steps to improve it.
Next, you’ll need to see if you have keywords that are getting clicks but no conversions. How do you do that? Well, hopefully you set up tracking at the keyword level when you first started your campaign. If a keyword is getting lots of clicks but has made no sales, it’s time to pause it.
After you you prune your keywords list, take a look at your ads, and start split testing your ads. Here is a little tip for you: create 3 copies of the original ad (so you’ll have 4 of the same ad), then create a new one by just changing the headline or one of the description lines. Now you’ll have 5 total ads running, but you’ll only be showing the new ad 20% of the time, preventing you from losing too much if the ad will not perform.
You should also figure out how much you earn per click. This is easier to do when you promote a product with a specific price, but it’s important to at least get an idea of your even if the products you promote have different price points. To learn how much you earn per click, divide your profits by the number of clicks you paid for. Now you know how high you can bid to break even. If your ad position is low, you might want to try increasing your bids to get your ad higher on the page, since ads at the top of the page usually perform better. Of course, always test: your specific ad may do better in position 4-6, rather than 1-3. Each campaign and product is different: one size does not fit all.
