(Sorry if formatting on this post is messed up - I keep previewing it, when when I click post, it loses all formatting!) So I run a discount code site, within the furniture niche.As a way to add further content to my site, I do product reviews.My site is about 3 years old now, and has never been penalised or had a manual warning, but has lost traffic and rankings as Google has updated. I've recovered to a certain extent on some of my main terms, but pages which used to to bring me organic traffic, reviews, haven't seemed to recover, and quite often are sitting at page 2/3.At one point my site did have "thin content" with small articles featuring new offers and discounts. I stopped doing these about 2 years ago, and started publishing guides and product reviews and comparisons (the reviews have affiliate links)As a way to combat thin content I "noindexed" my category pages. I have categories such as;"Reviews" "Brand 1 Review" "Brand 2 Reviews" Brand 3 Reviews" Even when I publish a new review, for a low organic competitive term, small search term, newly released product, once indexed, it doesn't always pop up on page 1. Sometimes as far back as page 3 or 4.What should I be looking to do in order to help new (and existing) reviews i've published rank? For bigger product reviews, I do try and link to them throughout guest blogging. However I can't do this for every review I write.Should i remove the "noindex" tag from the category pages ? Should I look to build links to these category review pages?What else should I be looking to do?Thanks in advance everyone.
