Re: My 2 cents
My £0.02 back on this.
I avoid price comparison sites like the plague. Whenever I've landed on one (perhaps because I've clicked on the link presented by Google thinking it was a retailer rather than a PCS) it usually presents a load of links to the product I'm looking for that are either:
1. Links to other price comparison sites claiming to have links to retailers for even cheaper (which eventually link back to this PCS)
Or 2. Links to retailers that either don't have the product in stock any more or never did in the first place.
PCS are a complete waste of time IME so perhaps this explains why you never got any decent business from the click throughs they generated to your site.
Not that I like Google, their creepy web stalking, or the behaviour alleged by this article; my only point is PCS are worse than useless as they claim to be able to source the item you're looking for when this isn't the case. Perhaps PCS ought to be reclassified as Click Bait sites.
