This question probably requires a bit of background.
About six months ago I opened my first online store. It was an Ebay store. Sometime later, I became interested in SEO and I created a free information site to compliment my store.
To begin with, only people who purchased something from my Ebay store visited the site because I could not get any search engine traffic. So, I added Adsense to the site and the money I made covered my hosting costs.
Then, the site took off in the SERPs and I suddenly began seeing a lot of more visitors there than I did on my Ebay store. Ebay's costs were cutting into my profit margin so I decided to close that store and build my own shopping cart.
It took about a month to complete and by this time I was making about $600 a month off Adsense. Because of this, I went ahead and added the shopping cart but I did not remove the Adsense from my original articles.
Now, I am a student and I need the Adsense money the original site makes to survive on so I wouldn't touch that with a ten foot pole. But I am about to open my second online store and I have pretty much followed the original site's design. Write articles (with Adsense) first and try to make the site popular then add the shopping cart onto it.
But, I am just not sure if I should take the Adsense off the new site or not. Analyzing my original site, I discovered that roughly 10% of the visitors which start on an article page end up going to a shopping cart page.
My Adsense CTR is typically around 10% so I figure that I am better off with Adsense. The 10% that go to the shopping cart are not making as much for me as the 10% who click on Adsense.
But, maybe those 10% are far more likely to buy something? Also, it puts me in the odd position of advertising for my competitors, who sometimes carry the exact same line of products that I do.
Does anyone have any actual experience with Adsense and shopping carts on the same site?
