1) Reducing the amount of adsense ad-space by about half

2) Experimenting with more obvious call-to-action buttons, such as “Buy Now” but in more prominent colours (Red buttons rather than Green, for example).

3) Adding the featured posts in the top right of the page, which link to the most popular products that visitors can purchase. I vary these weekly too.

I’m also getting some guest articles written for EnviroGadget using my new guest blogging platform http://www.blogsynergy.com, which saves me paying writers too.

Regarding article frequency, there is a limit to how much you can write about eco gadgets, as there is a finite number coming into the market place. I’ve found that around 5 articles a week is the right balance between interesting eco gadgets and fresh content.

There are a number of eco technologies that exist, but most are dull and my lack of interest would very easily show in the low quality of articles. Therefore I cherry-pick the most interesting gadgets.

The comments about selling adspace, using easy content units and whitespace have all been noted and are at the top of my to-do list.

To target eco-gadget buyers, I intend to do a mix of what Kirsty and Lammo suggest (a shop area, and detailed articles respectively), and I am brainstorming ideas along those lines.

Thanks for the ideas everyone!
