On one hand, long and ugly affiliate tracking links are a straight giveaway to people that you want to sell them a product (and people may be uncomfortable clicking on them). Therefore, making your link shorter and "nicer" looking will it give a more professional appearance. One of my favorite plugins for making links look "pretty" is the Pretty Links WordPress plugin.
*Yes: As you may have guessed, the link above is my two-tier affiliate link. There are a few of these links on this site to pay me a small commission and allow me to keep this site free instead of a monthly membership site. Using my two-tier affiliate link will not affect the amount of commission paid to you with this or any other program. My commissions are paid out of the vendor’s cut, not yours.
I’d stick with Amazon if I were you. All of my Amazon sites only have Amazon affiliate links. If you use Google Adsense display ads on your site, you’re literally taking people away from your site for the sake of just a few cents with these type of ads. If you direct them just to Amazon, then you have a greater chance of earning more money from that click.
In the 1990s, the term Digital Marketing was first coined,. With the debut of server/client architecture and the popularity of personal computers, the Customer Relationship Management (CRM) applications became a significant part of marketing technology. Fierce competition forced vendors to include more service into their software, for example, marketing, sales and service applications. Marketers were also able to own huge online customer data by eCRM software after the Internet was born. Companies could update the data of customer needs and obtain the priorities of their experience. This led to the first clickable banner ad being going live in 1994, which was the "You Will" campaign by AT&T and over the first four months of it going live, 44% of all people who saw it clicked on the ad.
These add review stars to snippets and increase click-through rates. I have tested many rich snippet plugins over the years and my favorite (and what I use now) is the WP Review Pro Plugin by MyThemeShop (view the demo). It’s fast, looks great (here’s a page I use it on), comes with 16 pre-styled designs, supports user reviews, and is well-supported by the developers at MyThemeShop. I was previously using WP Rich Snippets but the developer abandoned the plugin and hasn’t updated it for 2 years, and All In One Schema lacks customization options.
