Why most affiliate uses wordpress only?
There are other tonnes of website creation tools (Drupal, Joomla, WIX, Shopify) that was created in the web. However, why affiliate often like to use Wordpress only?
A short answer is easy and effective. Wordpress is easy yet powerful content management tools (CMS) in the industry. For affiliate which require regular update on the content, we needed a CMS tools to help on create new post/pages easily and effectively.
Similar products such as Drupal and Joomla have their own CMS tools as well. However, the community is not as huge as Wordpress. You might not get the help instantly just like Wordpress.
Community is very important. Same goes to WA. We are able to get help from the community instantly on the doubts that we have.
WIX is drag and drop website creation tools that enables you to create beautiful website. It is best recommended for offline business such as restaurants.
Shopify as most of you might know, it is for online business with shopping carts and payments methods. As an affiliate, we do not need those in our website.
