Assuggested, make the very most of your existing traffic. All too much time people look at the traffic they are not getting, but the answer lies in who is converting.
Here is a fun one that we just discovered. Look at your conversion rate of people who visit your site and use search vs. those who do not. I think you will find a big conversion difference. We found that those who use search on our site are 6x more likely to buy than those who don’t.
So my tip is: Identify what converts today and how, and then apply the improvements in that space.
For us, improve search, get that 6x to 10x.
