Google dance or drop?

Hi dude. Some days Ago I opened a thread saying my site has been spammed by some Chinese guys. Due that spam I lost just 1 position, I think due the good authority of my site.
On that day, I:
- made a disavow of all the spammy chinese site
- made 2 authoritive backlink DO - Follow, for get back some authority

Now my site lost other 2 positions. But doesn't seems to dance. Yesterday, This morning and now my site is in the same position, 3 position down than a month ago. Other sites on my SERP page are dancing very hard, though. I do not understand, is it normal my site doesn't dance while all the others dance? I will bounce back or this means I won't?

You won't know for a LONG while my friend. Just be very white with your SEO and very authoritative and don't over-do it. Given that its Chinese links and you sound like you have some authority built up you have a fair shot at coming out pretty clean. Only time will tell, nobody can answer it for you right now.

my site also get spammed. they send many wiki link. i check it with ahrefs and disavow it. but my rank is stuck on 2nd page. previously it on top 3 rank.

I also monitor SERP positions on a daily basis, but it's actually a bad habit and a waste of time. It takes months to see real trends and your time could be better spent creating authoritative content, with outreach, etc. Not saying that analytics are useless - but they only add value if you're looking at KPIs over the long haul
