Hello.

I've always been a fan of Yahoo's developer APIs due to their generous usage limits and flexible terms. However, recent changes to their T&Cs are concerning. They now prohibit displaying ads alongside Yahoo API results unless they're Yahoo Ads, and they forbid showing Yahoo search results next to other search engines' results. This impacts sites like Topicala.com and gada.be, as well as many example applications using Google AdSense. While their RSS feed search terms seem more lenient, allowing aggregation with other results and ads, the overall tightening of restrictions stifles innovation. I've updated Topicala.com to use the RSS feed as a workaround. I'm disappointed with Yahoo's approach, as proper attribution should be sufficient, especially when sites like mine prioritize Yahoo results. Until the licensing becomes more flexible, I can't recommend Yahoo's APIs.

I'm experimenting with AdWords to drive traffic to both this site and Topicala.com. So far, I'm getting about 60 extra visitors per day to each site. I've tweaked my campaigns, disabling ads in Google's search results due to high costs. While I achieved a high volume of ad impressions (600,000) for kinlan.co.uk recently, the click-through rate remains low, and I need better insight into keyword performance and ad placement. I'd love to hear any marketing suggestions. If you arrived here through an AdSense ad, please share your feedback and the referring website. I'm considering using ads to promote specific blog posts for increased visibility.
