Building Links In High Competition Niche Without Being Sandboxed?

I've had a lot of domains sitting for years gathering dust. Many of them ranked somehow even though they had 0 backlinks and not much content.

After I add more content and started building links, my top 10 rankings go down to 60, 120, then 300 within a week, and sit there.

Is this a dance? How long does this usually last? I noticed the big drop after I built some mediawiki links in the beginning of december... then on dec 6, rankings dropped a lot. But my competition has tons of links from the same wikis, plus much more spammy links. It's funny how it works...

Do I just need to keep buildling links and wait it out until the site comes back?

stop building normal backlinks and start make your content unique.

The content that has been added in the past 6 months is actually really unique and a good reference for anyone wanting to research.

Maybe I should add some outgoing links to my resources/references like wikipedia does. That looks more natural and authoritative...

if site doesnt come back with more links, you probably got tagged. I keep seeing people in this forum who probably got hit by Google spam team talking about dance.

I run an SEO company and on established sites dance almost never happens.

There are more reviewers in Google now than ever, and people think algo is making their sites move like that

I always build wheels, i.e. I blast my web 2.0 site that links to my interior pages etc.
My home page I manually link with. The interior pages help provide authority to my home page.. seems to work well...

take a look at your link velocity in majestic seo.

If you see a massive spike in the recent months, this is good.

Keep your link velocity constant at the new level if you do see a massive spike.

I don't think you can be sandboxed because of your link building even if you use xrumer
i never got sandboxed be sure to not leave footprint
