I am working on an web app, part of which grab contents from other several sites and show them in a merged way (partial info). Those sites are already dynamic and thus it will be super dynamic/changeable in every minutes. I was wondering to know, whether I can have seo benefits in this way, (as these are already exists in those external sites)? If doing some anything can help to get SEO on these pages, can you please explain how to achieve a decent SEO effect for these pages?Just to clarify one mis-understanding, I am not stealing the contents from other sites.I am using those site's api access to do this and its very much allowed. My main intention is to merge only the CLOSELY RELATED items into one place from several sites(using their api, of course), which will facilitate visitors to see them all in one place and save time from explore each sites separately. Instead using full contents, I am showing partial, so that, if a user get interested, then they can explore the full content page from their real owner sites and I get the credit for affiliation. Hope this make sense...
Merged Contents From Other Sites - SEO Effect

I would consider separating your services to one part explaining your app, your service, a blog - things like thatanother part grabs and structures the contentand placing them on different domains (www.ab.cd and sub.ab.cd).This way, should you run into problems, it will hopefully affect only one part (which is how some sites, hit by recent algorithms, try to re-structure or survice).Hints like rel=canonical won't help you much, as source is just a fragment of the content on domain A und target (the canonical content) is on a different domain with more than slightly differences in content. Also make use of webmastertools of Google and Bing and watch out for notices that should concern you.So if the intention of your site is clear and the service offers great benefit, a good search engine will honor that and you'll see benefit from that.
