More than likely Bonanza has the blank spots available to fill in but it does not mean you have to fill them in. Just fill in what you have. If you have no UPC or MPN to add, Bonanza will just tell Google shopping the item [URL removed] attribute so that Google shopping will accept your listing. There are items like yours that will not have a UPC or MPN as you say, so this is a good thing that Bonanza does this automatically with the attribute.

I’m not sure if you are familiar with Google shopping. It is basically a place that Google has where listings from many sites are all in one place.

Here’s a link to [URL removed]

Also, if you put vintage stamps into Google shopping’s search box you will get a populated list of them.

You can read up about Google shopping attributes on the internet (what is required and what’s not). In its totality, the attributes is like opening a can of worms…it cannot all be explained in one post. So just ask if you have questions.

And of course, Bonanza will also have your listings in their search on this site.

I think your product(s) would go well on a Pinterest page(s) (those of course without a watermark) – people in Internet land like real photos. That said – there are several sellers on here that run promos in Social media that could promo you (on Tweeter or make you a pinterest page. Or if you visit internet stamp clubs / groups – link an ad to your booth here and talk up your selection at the club site where interested parties are directed to a store that has their interest.

The key for many people is that the “product” has to be paced in front of them (I would say “daily” but enough times – 1 a week etc.) rotating through the “internet” views. If I wanted a specific type of stamp and typed it into a search engine – would YOUR store pic appear to me? if that is not the case – it might be a good time to learn pinterest (where you could do specific pages/titles for themed stamps – i.e. Africian, Animal, Building, Landmarks etc.) – I bet you will see an increase in your views fast and more views the more chances you have of sales. Yes, it is a lot of work – but when there are 80Million sellers out there, your items get lost in a blur and you need to make yourself stand out. Good Luck to you!
