Be more descriptive in my entries. Before I was being dispassionate (neutral) in my descriptions now I'm trying to give a fuller sense of what is available on a site.
Editorialize more: Say why I like the site or why it is useful or why I have reservations. The last happens rarely, because if I have reservations about a site it probably won't make it into the index.
I investigated displaying the URL of the listing, thinking that it would encourage more users to click through. It can be done but the templates for individual listings are very complex and a bit beyond my ability to edit. I'll revisit this in the future.
I'm considering thumbshots again and that these might also encourage click throughs. Gen X and later Gens are very visually oriented. Potential Problems include: 1. I have a lot of obscure sites for which thumbshots may not be available, 2. they add clutter, 3. They slow loading, 4. Thumbshots of slicker looking sites are more likely to get clicked upon while homely sites may get ignored so it becomes a beauty contest. 5. Thumbshot services are a third party silo. 6. Rendering on phone screens might be screwed up.
Still it's really a matter of flicking a switch back in the Admin panel, I can always turn it off again. If I'm going to experiment, it is easier to do now while I only have a modest amount of listings than later when the index is bigger so I might experiment with it for a year.
