We have been supporting blog for English learners (IELTS preparation) for almost a year and enjoyed a steady growth of organic traffic. The site was completely in Russian in .ru zone with only original materials written by in-house authors. At a certain point, we decided to launch alike blog for in English in .com and started to translate our own articles and publish them. We did this for months but Google does not get us indexed for some reason. We checked robots.txt, successfully uploaded sitemap to Search Console (it shows more than 50 pages), still nothing. We're confused and would be super thankful for any advice!
