Google Trends takes advantage of the Google knowledge graph for deeper understanding of entities and companies. This is showing "Pinterest the social network" not just "Pinterest the search term". You can toggle with the menu at the top.

I believe this is just a broader result set that includes searches for anything that Google deems to be related to 'Pinterest the social network'.

Google doesn't have access to internal Pinterest metrics.

Google also knows how many Android users search/download the app. I don't use pinterest, but if they use Google analytics or ads then Google also has a fair amount of data on usage.

Google is very much a panopticon, I doubt any other single entity has as much knowledge of the internet as a whole. Now whether this reflects in Google analytics I don't know, as I've never really used their analytics for anything serious.

Yet Google Trends exactly reflects (exhibits?) Google Play data of our app that has 37 million registered users.

And for "Facebook", Google Trends shows a 71% drop worldwide over the last 5 years. Their Q2 2019 earnings showed a 20% worldwide growth in monthly users over the last two years alone. "YouTube" shows a 45% drop over 5 years. "Google" itself shows a 60% drop over 5 years.

Google Trends can't reliably tell you anything useful about a site's growth or activity. I'm not denying it correlates with your specific app, but that doesn't mean it will work for everything, and it clearly works very poorly for popular services.

I honestly feel those numbers are correct.

Remember when everyone was sharing youtube videos. Or when you would sit and endless watch. I feel like that faded about 45%.

Google dropping makes sense. I visit less sites and the search results are not that great for discovery. Most sites I visit by typing a letter in the browser and auto completing.

Facebooks earnings raising 20% makes sense as more people are advertising on it. I notice 71% less people less original activity.. photos/status updates more groups/ads filling the gap. I spent 71% less time on and reduced my daily visits.

We're always chasing yesterday's tail. I bet twitter's numbers are down.

Facebook user growth was 20%. You said earnings.

And how do you know this is all wrong? At least I get to look at our app internal analytics and compare. Do you have access to their internal analytics? Also contrast this to https://trends.google.com/trends/explore?date=today%205-y&ge... . Instagram is 9 years old
