Split testing is what marketing is all about; right? Wrong! There is a much better way to get the answer to 95% of the kinds of questions you might consider split testing. Lets step through it.
First of all, you must decide your desired outcome. Is it profitability? Is it search engine ranking? Is it more traffic? Is it more inbound links?
Once you have decided your desired outcome, you must find a way that OTHER PEOPLES sites can be measured for that outcome.
Thats right; Im not advocating split testing because there is a much faster and even more accurate way to get the same results by simply looking at the results of OTHER PEOPLE!
Its called statistical analysis. Its what most scientific advancements have been based on! When you go to the doctor, does he split test antibiotics and exercise on you? Of course not! You would fire him immediately. Instead, he looks at the results of studies where other people had the same desired outcome you want (getting rid of that fever, cough, whatever) and prescribes the drug or treatment that was proven safe and effective for a statistically significant number of OTHER PEOPLE!
Will it always work for you...
