I don't think I've ever booked a hotel/b&b based on the breakfast. I'm a location/quality/price girl. BUT I do think that a B&B's breakfast description or page says a lot about the hospitality you'll get there, which IS a factor to me, especially since there's very little quality control over B&Bs.
If the rest of the website is attractive, informative and professional, I wouldn't notice the lack of breakfast info and assume continental or similar. But if the rest of the website is equally vague or seems to imply "we serve what we want, we clean when we want, we are hospitable when we feel like it" then I'd look for other options or check out their TA reviews.
I rarely book these days without checking reviews, and I trust them more than websites.
