We are both business sellers and use the same manufacturers for our goods. For this reason we are in direct competition.
I have long given up checking other sellers listings. All of my listings have a standard format and I price according to my own profit margins. There is no point checking the competition as you see sellers come and go who can only be making minimal profits. I do fine by these methods and see no need to change them.
The items themselves can be listed in only one way. We have permission to use manufacturers images but I always list how the manufacturers name them, then say NEW etc and sizes If applicable.
Today I got an email from a competitor stating that I have copied their wording on the listing heading and requesting me to change it. I have checked and except one word, they are the same.
I have expressed my concern at being accused of copying (I have worked hard to build this business) but have changed the wording around (although the words remain the same).
I am just checking that as this is a competitor, they cant do any damage. They obviously do spend time worrying about competition and are clearly put out by my listing. I have seen many a back-handed tactics over the years of trading and want to be covered.
