Welcome to the Q&A Forum

Also, I'm realizing that the 5% number is rather vague. To put it into perspective, it's just under our average conversion rate for that timeframe.

Yes, we've had some decent conversion rates from Reddit. It's been around 5% over the past couple of weeks.

Last week my ranking for "keyword A" was relatively high at 16. Since then it's dropped a staggering 31 spots. It's certainly the most important keyword we can rank for so seeing it go -31 spots is rather frightening.

I have a couple of theories:

1. We haven't included it in our blog content as anchor text but once in the past 2 or so weeks since the last crawl was done by moz on oct. 21. The lack of recent links with the anchor text of "keyword A" pointing back to the blog is causing it to lose it's rapport.
2. I've been adding most of our blog posts to Reddit and we've been getting almost double the traffic from Reddit alone. But with that comes a much higher bounce rate (~80%). Could posting and having visitors bounce from our blog posts cause the ranking to go down?

I would love to get your thoughts on this issue.

Thanks,
