(dot)shopify.com URL and SEO

Hey i had a shopify account with the URL set as - organicfood.shopify.com

- But i ended up created a totally different store for say pokemon.

So my stores using my custom domain - pokemonblahblah (dotcom)

But my original shopify url is still organicfood.shopify.com - totally irrelevant to the niche.

Should i be worried about this for SEO purposes in any way?

Should i make a new shopufy account - name appropiately - and migrate?

Or will this not make any difference what so ever in the SEO of my website and blog using shopify?

Thanks

Would be best to get a new shopify domain and migrate, yes. You don't want people seeing "organicfood", click and land on pokemons. Not good.

Even though I have a custom domain setup though?
