Landing Pages
Send paid traffic to landing pages for products not to the homepage. Or send paid traffic to categories that match the users intent. Optimizing landing pages is a must, if you’re not doing it read this article first.
Products descriptions and SEO
Use product descriptions, and make sure they are both engaging and original. There are reasons for both of these rules.The text description gives search engines something to index and well-chosen key words ensure that you can be found. Creating unique descriptions prevents you from being accidentally filtered out as spam by search engines.
Site-wide search means sales
Attracting customers to your site is only half the battle. Helping them find products on your page is essential to close the sale. And the best way to do this is with an easy-to-find and easy-to-use search function. Utilize every aspect of design to help it stand out: placement, color, cursor focus, and the all-important white space. And make sure to do your own on-site keyword analysis to improve descriptions.
Speed
Page abandonment is an avoidable annoyance for any website, but for sales-based sites it can be disastrous.
