Some article websites (I’m looking at msn.com right now, as an example) show the first page or so of article content and then have a “Continue Reading” button, which you must click to see the rest of the article. This seems so ridiculous, from a UX perspective–I know how to scroll down to continue reading, so why hide the text and make me click a button, then have me scroll? Why has this become a fairly common practice?
How does Google know if you interacted with something on the page?
Google offers an analytics package that a huge amount of sites embed. Many other companies like Facebook have software available as well. Mostly people have these to track performance of Google-published ads, but it gathers a LOT more data than that. You also don’t need to use their ad system to put it on your site.
Anyway, it runs JavaScript to gather information about everything that a visitor does on the site and sends it to Google. You can “opt out” by using a browser extension like NoScript. I assume ad blockers could work too.
For people developing or running a site, it really gives you a ton of useful information - where your visitors are from, what pages people viewed, how they got to your site (search terms, ads, referrers), how long they spend on your site, even a “heat map” that shows what parts of the page people hovered on with their mouse pointer. The tradeoff is that Google gets all of this information too.
Chrome. You’re likely using their product. They know everything.
I am not using Chrome.
Well, the majority of people do.
