Before diving into Ebay SEO, keep in mind that the Search Algorithm doesn't give a fig about your efforts. It was designed with the consumer in mind.
Ebay's SEO is based on a straightforward formula: views vs. sales. Ebay keeps a close eye on the correlation between the number of views and the number of completed sales. No matter how many times your product is seen, you will not be able to rank higher if you have no sales, but a rival with less views and fewer sales may be prioritized.
There is no Hacks, Tips or Smart Tricks to fulfill the algorithm criteria for better ranking and visibility. All you need is skills or an expert's hand holding and training. You can subscribe us here to improve your Ebay Selling Skills.
