I'm not that familiar with headers but I thought the Last-Modified was optional and not available for all sites. It says seotoolsforexcel was last updated in 2016. Hmm.
How about you use the =WhoIsDomainUpdated("https://www.seotoolsforexcel.com") formula? Alternatively, you can use the Wayback Machine connector to check when a page was last indexed. Also you can check specific headers for any site with =HttpHeader(url,header)
Oh... OK, will use WhoIsDomainUpdated. Thank you!
PS: here you are showing the panel for setting up the Wayback Machine. How to open it?
It is located in the SEO category
No, that is not normal. What version of Seotools do you have installed?
SeoToolsVersion()=8.0.86; Excel 2019 x32 Rus; Windows 10.1709 x64 Rus.
Is it only Wayback Machine or other connectors as well?
Almost all connectors behave as well, except SEO - Ahrefs\Google CacheDate\Google Search* and and maybe a couple of others...
behave as well = works or doesn't work?
Can you try this build:
188.8.131.52_20190103 doesn't work, 184.108.40.206_20190109 works well!
Thank you! Bye!
