I've got an old site with millions of optimized pages. I haven't made a change to one line of code on this site for three years (outside of adserver code). Three years ago, my traffic would spike to as high as 68,000 uniques per day and would gyrate with some consistency from G.
Then one day about 24 months ago the gyration stopped and traffic was throttled down. My G analytics graph was nice and smooth with a general downtrend day after day after day, week after week.
Until I was down to 4000 uniques per day, every day from G. Then 60 days ago, it stopped.
I've uploaded a screenshot from G analytics for last 30 days, compared to last year, check it out:
Two things occurred, both related to backlinks, which I think let G free this site:
1) I was leveraging the traffic to distribute widgets that had rotating anchor text to a couple of other sites. G caught me a couple years ago (30 months) and penalized the sites with the anchor text and slapped this throttle on the distribution site. I cleaned that up, told G what I had been doing and my other sites had a 3 month penalty removed, but throttle continued on primary site.
2) I add hundreds of backlinks in rotation but ONLY to site with a throttle on it...I think over time (2+ years), the backlink structure cleaned itself up and the true power of the site was unleashed again.
Now traffic is growing like crazy from G as all the millions of pages are recrawled. 500-2000+ uniques every few days. I am a little worried my server will crash if I hit 30,0000 uniques per day. Might need to pull out the load balancer again.
Anyways, throttling scares me. But the way out is through reworking your backlinks, that I am quite certain.
For now, I am enjoying the increased ad revenue. :-)
