Question: A common occurrence on my site is that pages will after about 4-5 months live start to rank well. Granted, the search traffic is coming from long tail queries but the associated content is popular enough that I wind up getting some decent traffic. I would say on average when the traffic gets good, the rankings remain unchanged for 6 months to a year. And usually after a year these once highly ranked pages are are pretty much buried and the traffic goes down to zero.
My question is, is there anything I can do to "fix" these pages and regain traffic once again. Or has Google "flagged" these pages as low quality and there really is no hope for the future of these pages? I'm kind of surprised Google has not just "labeled" my site as low quality and no new pages will never rank well at all...but luckily that's not been the case and there is almost no end to how many new pages I can create in my industry. Appreciate any thoughts about whether it's worth trying to "fix" these pages or is there almost a lifetime ban on these pages now?
