Hi,
I manage a NSFW website selling toys+lingerie (on DVD, movie, or anything like that - yes there is a huge distinction) -
Anyway, we were hit with a manual link penalty a few years back, we resolved that (confirmed by G), but since then we've never really recovered. We have a disavow file with about 1000 domains in it, which we add to at least every month, trying to shield ourselves from potential problems.
In July 2014 we changed URL's to the current URL from the old NSFW URL with a view to leaving the past behind, copying the disavow file over to the new domain. For the first month we bounced back, and thought we might be okay, but alas since then we've been on a steady slide back down, and way below where we were in July 2014 even.
In the last 9 months we've taken massive steps in removing old products (10000 down to 2500, with 301 redirects on old to related new), consolidating products into groupings (small, medium, large, black, white, red, green etc), adding plenty of movies and videos to the site to showcase products, encouraging customers to come back and post reviews on the site, reducing our server load times, implementing good cross linking between products to ensure customers can better find related products. We've also run in-depth scans on the quality of our copy/content, using copyscape, screamingfrog and siteliner, and replacing, removing, adding to any and all descriptions which looked bad/thin/ugly or simply didn't sell the product well. We've learnt our lesson, we've really improved beyond site of where we were. Time on site has increased, pages viewed, and we think customer engagement has improved. The site has been mobile friendly for over 12 months.
We've also been doing a lot of PR, and interviews and talking about the right things, and tapping into our network of customers to gain seriously good quality links (very few, but good quality) from top notch magazines and publications. We have all of the new good quality links point to our new domain, we have no bad links pointing to this domain directly, and it seems only bad links pointing to our old domain (although they are disavowed anyway).
My only thought is that the old domain is a ball and chain holding us back, and possibly dragging over a undeserved penalty.
So, this all sounds great, BUT we've seen zero improvement in rankings or traffic. In fact since December our traffic has actually declined.
My questions are ->
1. should we cut the old sites 301 redirect to the new site? Is the old domain a chain and ball around our neck?
2. Also - If we made the old domain parked/null, would the old-url's hurt us with duplication? What about other people who scraped our old site, and we switched over the new site later than they scraped?
I'm interested in the thoughts of the knowledgable guru's here!
