How long after https migration that google shows in search console new sitemap being indexed?

[lcourse]

We migrated 4 days ago to https and followed best practices..
In search console now still 80% of our sitemaps appear as "pending" and among those sitemaps that were processed only less than 1% of submitted pages appear as indexed?

Is this normal ?
How long does it take for google to index pages from sitemap? 
Before https migration nearly all our pages were indexed and I see in the crawler stats that google has crawled a number of pages each day after migration that corresponds to number of submitted pages in sitemap.

Sitemap and crawler stats show no errors.

thanks Stephan.

It took nearly a month for search console to display the majority of our pages in sitemap as indexed, even though pages showed up much earler in SERPs. We had it split down into 30 different sitemaps. Later we published also a sitemap index and saw a nice increase a few days later in indexed pages which may have been related.

Finally google now is indexing 88% of our sitemap.
Do you think in general that 88% is for a site of this size a somehow normal percentage or would you normally expect a higher percentage of indexed sitemap page and investigate deeper for potential pages that google may consider thin content? Navigation I can rule out as a reason.

Did the "pending" message go away in the end? Unfortunately you're fairly limited in what you can do with this. The message likely indicates/indicated that one of the following was true:

1. Google had difficulty accessing the sitemap (though you did say no errors)
2. It was taking a long time to do it because of the large number of links

You could try splitting your sitemap up into several smaller ones, and using a sitemap index. Or have you done this already? By splitting it into several sitemaps, you can at least see whether some index and some don't, whether there do turn out to be issues with some of the URLs listed there, etc.

You can also prioritise the most important pages by putting them into their own sitemap (linked to from the sitemap index, of course), and submitting that one first. So at least if everything else takes longer you'll get your most important landing pages indexed.

Update. now 10 days passed since our migration to https and upload of sitemap, still same situation.

Google has been crawling all our pages during the last days. I see it in the crawling stats.

My concern is that

1. majority of my sitemaps are still showing up as "pending" 3 days after I originally submited the sitemaps.
2. those sitemaps that are processed show as indexed only less than 1% of my submitted pages.

We do have around 170.000 pages in our sitemap.

So I wonder wheher this is unusual or normal delay from google search console.

Its difficult to say. It depends on many factors like (importance of your site in Google's eyes, when they crawled your site the last time, relevance of the topic in general, etc.) BUT you can speed up the process a lot, i.e. initiate it on your own. You don't have to wait until Google recrawls your site at random. Did you know?

Go to Search Console - Crawl - Fetch as Google - Add your site's URL or URL of a particular sub page. Press Fetch

Google will recrawl that page again very quickly. When I do that with a particular page (not the entire domain) it usually takes 1-2 days at most to recrawl and index it again.

Hope this helps.
