ad space is a rock solid plugin, which I highly recommend that you consider.
i've yet to redo the page on my site, i'll be posting a demo sooner or later, and i'll likely be selling it as a separate product shortly. in short, though:
- it lets you define ad blocks for use as stand alone components or in ad distributions
- it lets you define ad distributions that display a predefined selection of ad blocks in predefined locations on your page (e.g. below the header, above the posts, in the sidebar, etc.)
- it lets define which ad distribution goes to which context (page, post, home...).
in the future, these contexts will get more diverse (e.g. post when user lands from a search engine). and I'm looking into many other features of interest to you.
the point being, ad space is not your average adsense inserter. it is a product that is being built with niche marketers, for niche marketers, with ad distribution maintainability and page view revenue maximization in mind.
