Webmaster Tools Search Queries Data Drop

[MonicaOConnor]

My opinion is that there should be more data in GWT than in GA because "not provided" is not accounted for in GWT. There is no data loss with the updates in GWT in Feb, only a longer lag time between reports.

Has you data always matched prior?

[Dan-Lawrence]

I've never really looked to see if they actually match to be honest, its not so much a about them not matching exactly, just that GA is reporting visits from organic search (specifically from google) as per normal/as it has done for last couple of months and GWT reporting sharp decline in impressions and almost zero click thrus (i attach a screen shot of the GWT dash).

Also a weird anomaly in GWT ive just seen today is that crawl stats crawl an average of 55 pages per day (last data point the 22nd Feb) whereas the sitemap index section is showing 65 pages submitted but only 16 indexed (which i'm sure is a drop and most were previously indexed). And Google index status is showing a sudden drop in indexed pages from the 15th to the 22nd going from 64 to 30 indexed pages).

What is your server response error? How about the sitemap warning? I would be interested in seeing if the data in Panguin Tool showed anything weird going on with the update in the middle of February. What Google has indexed vs crawled shouldn't matter to your impressions and clicks.

Usually, I have more data in GWT than in analytics. I would go to Acquisition - Source/Medium and check the amount of unique traffic (not the total sessions, just the new sessions) from Google Organic and compare that to what you see in GWT. They should be more closely related to each other. My numbers never match exactly.

Server error - im not sure since marked as fixed to see if old error and will see if it comes back but had been reported since December and these GWT issues only started on 9th Feb

Similarly the sitemap warning was first observed in October so didnt think would have anything to do with it. Its a 404 to do with a 'page-sitemap.xml' with the following message:

When we tested a sample of the URLs from your Sitemap, we found that some URLs were not accessible to Googlebot due to an HTTP status error. All accessible URLs will still be submitted.

But when i click on the example url it actually resolves with the correct page ok, so again didnt think this woud have anything to do with recent GWT issues

Panguin screenshot attached - doesn't look like anything since GA data is showing traffic and s light increase over mentioned period/after final yellow line which i presume is G update you refer too ?

Regarding: "Acquisition - Source/Medium and check the amount of unique traffic (not the total sessions, just the new sessions) from Google Organic and compare that to what you see in GWT"  Here i've gone to Source/Medium > Google Organic Then i've clicked 'Other..' ? 'Users' > 'User Type'. (Is this the best route to the data you mean ?). In here New Visitor and Returning visitor are listed with New Visitor saying 406 visits (same period in GWT is 393 so v close).

You don't need to add a secondary dimension. I just look at my traffic. For example, I had 1627 Google Organic visits last week. 60% were new sessions, or unique visits. That tells me that I should see about 975 clicks for the week in GWT.

I am not sure what is causing the discrepancy. In my opinion the issue isn't with what is in GWT. The update they submitted didn't affect accuracy of data, it was merely implementing the ability to compare data sets over a period of time.

ok thanks Monica

yes it does seem very strange and im very worried about that sharp fall in search impressions although cant explain it since rankings havn't fallen and neither has traffic from organic search, but impressions look like they are falling & consistently getting worse

[Dan-Lawrence]

Hi Monica

Im noticing even less pages in the sitemap index in GWT now so thinking could still be a genuine problem issue rather than data issue with GWT

Ive been looking a bit more in depth at ranking pages and notice that site went HTTPS in early Feb and the impressions started to drop almost straight after:Some previously well ranked HTTP pages dropped to the 50's - 60's suddenly in between the 4th - 11th Feb to be replaced in the high rankings soon after by their HTTPS equivalent/replacement. This time frame is exactly when the GWT impressions drop starts.The HTTP pages are still ranking though, so could the fact that pages are falling out of the index, combined with HTTP pages still ranking signal a possible dupe content issue causing the drop in impressions, and i should tell dev to delete or fwd/redirect the old HTTP pages now HTTPS are live ?If this is the cause, could it be a permenant problem or should deleting/redirecting solve it ?Just a thought !?------------------------------------------------------------Edit additional info:Ive just seen this article: https://www.seroundtable.com/google-webmaster-tools-http-https-19965.htmlThis makes me think need to set up a whole new webmaster tools profile for the HTTPS version and also explains loss of impressions etc for HTTP - so loss is nothing to worry about since impressions now being achieved by the HTTPS site version ?

[Dan-Lawrence]

Just looked into this further and the HTTP to HTTPS migration totally explains it IMO

[MonicaOConnor]

I agree. You will need to add the https version of your site to GWT. Google sees these URLs as two different URLs, so you will want to add the HTTPS version of your site.
