Hi,
I agree that adding a link to the directory in the home page would probably help.
Did you see this article on how to solve block resources? https://kb.yoast.com/kb/fix-blocked-resources-google-search-console/
However it appears that only 1 page of your website is affected by that blocked resource, so I don’t think the drop in indexed pages is related.
There are plenty of reasons why Google may choose to drop pages from their index. This is what I’d do:
– Make sure you don’t have short/duplicate titles and descriptions. A lot of our forum topics aren’t indexed because of this.
– Check to make sure the content on those pages isn’t duplicated somewhere else on the Web.
– Check canonical links are correct for pages that are dropped.
– Make sure the sitemap currently on the site matches the one you submitted to Webmasters-
– Make sure the quality of the pages is worth indexing.
– Did your traffic take a hit? If it is not substantial it is possible that it is de-indexing pages with very low traffic.
– Can you check if any of those pages is receiving spammy backlinks?
Hope this helps.
Let us know,
Thanks
p.s. there are 104k pages indexed at the moment not 70k.
