Sites labeled as cluttered mean that I have found these websites to have one or more of the following: Pop-ups, too many ads, ads with movement, ads dropped within the article, video boxes running, and that long stream of content near the bottom of the webpage that looks like other articles (at a glance) but is actually just sponsored content.
There are ways to use software to block ads (for example pi-hole) and you may always use a browser like Brave to block ads, but the website will still show the cluttered, now empty, ad spaces. I’m not completely against paying for website costs with ads, but the overuse of ads has tarnished the browsing experience.
What other elements would you prefer not to experience on the websites you visit?
