If your site runs from a database, you can download the content tables and use find/replace to fix those hardcoded http: requests. Otherwise it might need to be one page at a time. Thing is that if the third party does not have https: you'll have broken images.

How's your traffic besides AdSense?

Mine has also dropped 62%. I have changed nothing and page views are up.

I'm wondering about this "drop" ... Has your denied clicks gone up as well, or has it nearly disappeared? What you might be seeing is g finally getting the accounting straight on what has been served and what has not.

Hi traffic is down 15% only... I submitted a support ticket to adsense. Anyone wanna suggest some checks to be made? Thanks!

I had an unsuccessful SSL conversion a year ago. Luckily my viewers informed me right away so it was only live for ten minutes. What happened was anyone that viewed the site got a 301 redirect as instructed by the setting in nginx. That cached the mapping of content in their browser. The only way to undo it is for the client to clear their cache. An incorrect setup live for very long would bad.

I don't think this has something to do with the SSL. Check if this drop is mostly on mobile devices, it would explain some things.

I think it's to do with SSL only. The problem was that #*$! cpanel software automatically deleted our entry for SSL certificate, module etc. and activated an old certificate laying in our server. This was expired. I found this about 10-11 hours later.

I think Google didn't like this and it's messing my earnings. So I'll talk to support & see.

It might be just a coincidence. I had a crazy March, with a lot of ups and downs, CTR cut in half (from 0.5%, not from 3% like other people) to finally discover that now my mobile ads have the double check "feature" (Visit site). Ad requests, Coverage and CPM were, of course, also affected.

Dig carefully into your performance reports.

That SSL certificate might be the nub of the problem.
Fix that and report back.

Money is always down at start of month - it goes up at end, and back down at start.

End of march is always always very high - as it's end of tax year and remaining advertisers budgets are being spent before new tax year.

It also schools holidays now too - which can have a big impact on advertisers spending depending on niche.

My earnings are down - my site has had stable traffic for over 7 years - it's the same every year - you can predict adsense earnings like clockwork when you know how it works.

Don't worry. It's probably nothing you've done.

If possible, I would send a trouble ticket to your host.

Well my Google search traffic (referral) has gone down by about 45% and Adsense supports just says about the same thing ie lower traffic.

The question is, if Google Search did not like my expired SSL certificate (which was online for about 10-12 hours) how do I fix this prob? Can I resubmit the entire site on the Google Search Console (webmaster tools)?

Any suggestions on how to fix this SERP issue now? Thanks!

Assuming the certificate issue is fully fixed, you would just have to wait for the site to be crawled again. Since it's been 4 days already, I would expect traffic to start picking up again, if the drop was indeed due to the certificate error.
