Hi, would you guys recommend using a backlink service like this? https://www.peopleperhour.com/hourlie/gain-30-links-from-30-top-newspaper-sites-in-the-uk/396519Or is this the kind of thing that leads to being penalised?Over the years, I've always been told this is black hat and dodgy. Is that always the case?

I've recently put some query string parameters into links leading to a 'request a quote' form which auto-fill the 'product' field with the name of the product that is on the referring product page. E.g. Red Bicycle product page >>> Link to RFQ form contains '?productname=Red-Bicycle' >>>> form's product field's default value becomes 'Red-Bicycle' I know url parameters can lead to keyword cannibalisation and duplicate content, we use sub-domains for our language changer. BUT for something like this, am I potentially damaging our SEO? Appreciate I've not explained this very well. We're using Kentico by the way, so K# macros are a possibility (I use a simple one to fill the form's Default Field).
