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?
The biggest reason I leave a page is paywalls and ads.
Some of my clients do not have the budget to give you free content without ads. Even a (usable)shared hosting server costs around 25 bucks a month. Add in dev time and design, small mom and pop sites can’t afford to be ad free.
Only the big dogs do paywalls.
