The SEO Blackhole in Deal Aggregators and Price Comparison Portals

We’ve seen comparison and aggregation sites that are built on content and getting most of their users from search engine traffic. This guide is meant to help you do the best you can in search engines.

Looking at comparison sites/aggregators, and also Google’s content guidelines, it is very important for these sites to think about long-term rather than fixing things in short-term. So for these sites, the best way is to choose between

When most of the aggregators go with the first option because it is pretty easy compared to a content driven approach, here is the catch.

From a Google’s perspective, an extra copy does not add any valuable information to search users, it’s just another blob of text to index and store (or, in many cases, to ignore). It simply doesn’t matter whether you are a comparison site, aggregator or an affiliate, Google gives no consideration for your pages as long as your content is copied from other sites, even if it is from an authorized supplier site. You won’t be penalized for copyright violations but that doesn’t mean your pages get better ranks in search indexes.
