Blogdigger explains their concern with re-syndicating search results:
“Our Terms of Service state that our search results feeds are licensed only for individual, non-commercial usage, meaning, they are meant to be used by individual people subscribing in aggregators. There are many sites that take content from Blogdigger (as well as other RSS-output services) and automatically post it to web pages in an effort to increase their search engine rankings with folks like Google.”
…they add that this has become even more of a concern when ads are incorporated into RSS feeds.
My query is that the content doesn’t belong to Blogdigger anyway, it belongs to the the various blog owners…but I suppose they supply a service of delivering search results - the content packaged in personlised ways, ie. allow you to monitor RSS content according to your information needs, you can’t do this on a big scale (rss sphere or blogosphere) without a search engine.
But I’m not savvy on advertising so I’m not sure how it works, because if someone re-syndicates your content they will be getting the ads appearing in the website/blog as well, and if they click on an ad won’t that be good for whoever owns the RSS feed?
…For monetary reasons I see ads in RSS feeds as a bonus as now wherever your content is re-hosted people can still click on ads and make money for the original host.
