Contents farm, scrappers, aggregators real world examples?
Could you plz 1st clarify me:
1. Is efreedom.com a scraper site, and not a content farm? I think it's scraper because it copies and pastes contents from stackoverflow.
2. Are ehow.com and squidoo.com contents farm? They don't copy and paste contents they just generate fresh new user generated content, but too much and too quickly.
3. Is expert-exchange.com NOT a content farm or a scraper site, isn't it?! It's simply that many people (and me too) hates it (they also wrote to Matt Cutts) because it shows up hight in Google providing a useless question with no answer.
4. Finally there are also another type of sites like this one: http://www.hotfrog.it/ It looks like a 'contents aggregator in the form of specialized directories', I don't know how to else define it.
There are many sites now on the web that work in the same way of hotfrog:
Basically they search for all sites of the same type i.e. “restaurants websites”, they copy and paste the contents found in “Restaurant A” and create in their aggregator site a new page called “Restaurant A”, then they do the same for all websites of the same type, thus creating a sort of directory of restaurants.
Later on these sites also sends an email to the owner of “Restaurant A” (usually the email is on the website) with a user and password to let him modify/update its own page.
Someone could call these simply directories, but I think a directory is different because is something you need to add your site into by filling a form and not something that steals contents from your existing site without a specific acceptance from the site's owner.
Do these type of sityes have a definition/name?
