Top 20 Website Annoyances (Clickbait sites excluded)

We've all been there... You clicked on a link, and right before the website was fully loaded, a popup form leaped in front of the page!
It asked you for your email address, so you might receive its latest news, updates, ebook, coupons, discounts, special gifts, etc. As much as saving a 10% on your online purchase sounded like a good offer, but you still found the diversion awfully annoying.
Here are the top 20 irritants to avoid for your website-- unless you aim to drive the site visitors away... FAST!
Pop-up windows on entry
Pop-up form that forces user to sign up in order to View/Access the site
Auto-play videos, sound files, any blinking and flashing paid advertisements
Pages without navigation back to the original source
Slow loading times
Disorienting animations
Flash splash pages, Flash sliders or any type of Flash -- Note: Flash does not work on mobile devices such as iPhone/iPad
Cluttered content
Tiny little fonts
Giant fonts
Ads, ads everywhere
Excessive graphics and illustrations
All text -- the opposite of number 12!
Articles or slides broken into multiple pages - How many "Next" do I need to keep hitting to get the end?
Infinite scrolling page
Confusing call to action
Outdated website design
Broken links
Lengthy sign-up process
Lack of contact information or search capability
