Very Nervous....stats way down

So I own 2 forums.

Nerdpoint.com and talksecondlife.com

Nerdpoint.com has used vbseo for almost 1 year. It worked great: until about 2 weeeks ago.

Traffic had been steady for months: 300-400 organic uniques from google each day.

almost 17,000 pages indexed as well.

Late last week I noticed a significant drop in my google traffic. I queried google and it returned only 302 pages indexed where there used to be 17,000.
I didn't panic but these numbers have still not changed and my traffic is around 60-70 uniques per day now.

with my other forum: talksecondlife.com, the same thing happened. It had about 2,000 pages indexed and now its only showing around 750. Traffic hasnt moved that much but Im still worried.

Any idea what happened? I havent touched anything for months.

You may have been impacted by a recent Google update. Did any new competitors emerge?

Did you maintain a relative-only linking strategy?

There's still a chance that it may be a short-term fluctuation.

Keep us posted on the activity for the next few weeks.

google is updating everything pr/backlinks etc you should give it afew days.

How is the backlink situation now?
