You want just the facts.
Clear pictures and description.
Fancy backgrounds, animations, special fonts all distract from getting your message quickly to the buyer. They also may also cause the page to take longer to load. Many buyers will leave if they cannot figure it out within seconds.
Your descriptions are hard to read as lots of information is jumbled together. They should be nicely formatted easy to read short paragraphs. Use bold to emphasize rather colors due to color blindness.
"We suggest you can order direct from us at [phone removed by eBay]. Or www.sure-grip.com."
Attempting to put your contact information in the listings, as well as trying to use eBay to do business off of eBay, will get your account banned fast. You need to remove all that pronto.
Use consistent background materials such as a roll of gray low pile industrial carpet for larger items. Smaller its can be placed on a table with a small piece of background material underneath it as its easier to work at waist level. I use six foot treadmill mats on 6 foot banquet tables with foldout legs.
Take pictures on the shaded side of a building using a dedicated crop frame or full frame camera. It produces better and faster photos than a cellphone.
Get rid of all that other stuff in the pictures. You just want to show the product. If you must show a larger portion of the item to indicate the part's relationship then superimpose text over the image stating that the other pictured parts are not included. Dishonest buyers can try to scam you by claiming these items were also included. Many other buyers don't bother to read the description and could be honestly confused into what it included.
The best listing software is GarageSale for Mac computers. In recent times they have moved to a subscription model. After purchasing the application you can upload 50 items per month with no further cost. If you upload more than 50 its $14.99 a month or $149.99 for the whole year. Your listings are stored on your computer for as long as you like - not a limited amount of time eBay will store them. Way faster to list with GarageSale than using Seller Hub.
You also need to look into shipping costs. Keep in mind that if a package is more than a cubic foot and its sent USPS you will be paying the higher of the dimensional rate or the rate based on its actual weight. Also be aware there are surcharges for items longer than 22" for USPS.
In GarageSale there is not need to input the package size if you are shipping USPS and its not more than a cubic foot or more than 22" in length. As that fits most packages I send, that saves many hours of work.
For UPS always input the dimensions in your listing regardless of size.
