Conclusion
These are some great techniques that you should consider implementing when trying to refine your campaigns and optimize your campaigns for cost efficiency. By performing just a few of these tests, you will be able to determine which landing pages work and why, how well your pages are converting into merchant click-throughs, and through trial and error you will be able to create much more efficient campaigns.
We suggest that you adopt testing into your day-to-day activities. You will not only benefit from it in the short-term, but you will be continually maximizing your profitability and save yourself thousands of dollars in the long term. We have wasted tens of thousands of dollars over the years on keywords and landing pages that simply do not produce, and if you can limit these through testing you can keep this money in your pocket.
