How eCommerce sell their product
eCommerce sites pay a lot of money to make sure that when someone searches for a product their listing comes up to the top. If you cross list on more than one site then your results will appear from all those sites on Google.
Lets see an example
We originally listed a shoe for a client on eBay. Check out the image below.
After finishing this listing we right away listed the shoe on Mercari and Poshmark.
Soon after posting we checked out Google...and viola!
Now DailyRefinement controls 3 of the top search results and is the only one to have brown shoes appear at the top!
