New game: ignorant blogger or SEO?

I was looking for baking recipes that use potato, and this is the summary for one of the first hits:

Potato cakes that are made with leftover mashed potatoes. These lovely Cheesy Mashed Potato Cakes that are soft from the inside, but golden and crispy from the outside! Make sure to check out my Vegan potato cakes with rice and carrot, they’re to die for!

And now I can’t stop thinking about how this poor soul doesn’t know that potatoes are vegan.
