Sudden Drop in Indexed URLs

[sekhar540]

Hi Everyone,

I am working on https://jobs.lallabi.com and https://realestate.lallabi.com, I have submitted 35 lakh and 15K URLs to google respectively through sitemaps. One month back I found that Google was indexed 4lakh and 10K URLs respectively. After that I have done some changes in Content and used Popup. Within 20 days the indexed URLs gone back to 16K and 1.8K respectively.

I have questioned in webmaster forums, one of the employees from google given reply with few corrections on canonical tag and on popup issue, I have done all and resubmitted sitemaps on 4th December. But still it is going back and there is no improvement. I am unable to find the proper reason behind this. Can anyone help me to solve this issue and to index all those URLs again.

Here I am adding the conversation link with webmasters forum.
