Oh my my ._.
OK so here's the situation. I started my site in 2009 and have used Coppermine for the entire time. Up until about 2011 or so we had AWESOME traffic, mostly from the gallery. It was like a dream come true and the site was very successful.
But then... starting in around 2012 the popularity of the site randomly started to plummet. Our traffic went down and down and down and now we're at a fraction of where we once were... and I mean a fraction
But out of sheer chance and random googling last night I worked out that the problem is that Google is refusing to crawl the gallery. It's crawling our forum just fine and seems to go to the main page of the gallery, but doesn't really seem to go in any further and crawl the well over 12,000 pictures that we have. Bing is doing it, but Google isn't, and as the vast majority of our traffic was coming solely from Google image search... what on Earth is going on?
I have checked the robots.txt files and I think they're fine.
I would appreciate so much if someone could help me with this. The site means a lot to me and it's had such a great run and a fantastic community. Fixing this surely relatively small problem will I think totally reverse the trend of our traffic numbers and we'll be back on the way up again! Exciting
Thank you to anyone who wants to help,
