A good eBay item title uses core product keywords that describe the item.
eBay gives you 80 characters to write your product title. Many people advise to try and improve eBay SEO by filling the 80 characters with as many keywords as possible.
This is not a good idea for eBay SEO. Cassini decides your ranking not only on your listing title but also on how customers engage with it.
Cassini compares the number of impressions your listing has, with the level of engagement. From this, it determines how relevant your listing is, and where it ranks in eBay search results.
Every time a customer searches a keyword which brings up your listing, Cassini counts this as an impression. Even if your listing is result 22 on a page where the customer only looks at the first 2 results, being on the page counts as an impression. If the customer then adds another keyword or uses category filters, and your listing is a result again, that’s a second impression.
Item specific options display in the left column on search, enabling buyers to narrow searches down by feature.
