Well quick post. My 9 niche website is ranking on top 2 pages of Google. And four website is indexed but no where in Google top pages. looks like they are in 100 or 1000 pages. i don’t want to track ranking of these. These website have searches higher than 1k-4.4k. Also, I my going to add 18 such websites. So, my wild guess. 12 of these websites will be ranking on top 2 pages very soon.
Other factors: 10 websites is not exact match and many are info domains. So, looks like they are going to fail. but yes if they will be seen in SERP. I will promote them massively.
Also, i have to outsource more content and add 10 extra websites. I still have 107-54-21-1=31 domain names. and content ready. So, i will launch some bigger sites from this month.
