A browser extension is a plug-in that extends the functionality of a web browser. Some extensions are authored using web technologies such as HTML, JavaScript, and CSS. Most modern web browsers have a whole slew of third-party extensions available for download. In recent years, there has been a constant rise in the number of malicious browser extensions flooding the web. Malicious browser extensions will often appear to be legitimate as they seem to originate from vendor websites and come with glowing customer reviews.[27] In the case of affiliate marketing, these malicious extensions are often used to redirect a user’s browser to send fake clicks to websites that are supposedly part of legitimate affiliate marketing programs. Typically, users are completely unaware this is happening other than their browser performance slowing down. Websites end up paying for fake traffic number, and users are unwitting participants in these ad schemes.

Create a website about the topic that you have chosen. The key to succeeding with affiliate programs is to build a content-rich website with useful information built around a specific theme. Don't just lazily throw up a quick site or blog and string a bunch of affiliate links all over your pages. You have to start by building credibility, and the best way to do that is to write about something you know a lot about.

I always add an HTML table of contents to posts to make sure they are long and structured. This has been a HUGE help for me (and my readers) and there are tons of benefits: better chance of getting “jump to links” in Google (see below), increased average time on page, decreased bounce rates, and it makes it easier for readers to navigate through your content.
Affiliate marketing is often touted as a "get rich quick scheme" by shady sites offering pyramid schemes that promise quick cash for little effort. Make no mistake—successful affiliate marketers like Pat Flynn of Smart Passive Income put in a lot of effort toward building an audience and creating quality content that will bring in sustainable passive income. Expect to do a lot of legwork up front—but if you play your cards right, you can build a solid source of revenue over time.
