Which site as main site? B2C or B2B?

[agctyz]

We're currently running two separate sites, one being the "main" page for B2B customers and the other being an online shop targeting B2C customers.

Site structure looks like this:

<code>[sonnenschirme.at](sonnenschirme.at) = main page / B2B</code> 

<code>sonnenschirme.at/shop = shop / B2C</code>

We're also building a new shop with Shopify which will replace the current shop and it's going to provide a really great user experience (AR models of products etc).

Naturally, there are a lot more B2C customers than there are B2B customers (we sell sun umbrellas). The B2C customer type spends around 150€ typically, whereas a B2B customer needs consulting and will spend upwards 10k. B2B is responsible for about 90% of revenue.

Both customer types seem to search for the term "sonnenschirme" which is basically just "sun umbrella".

Before the shop was accessible at a subdirectory (/shop), it was available on a different domain (not even subdomain), which was really bad for SEO. Once we consolidated both websites into one we've seen a big spike in traffic, due to products etc. of the shop ranking well.

As pretty much all competing companies are B2C companies who fight for a share of the "sonnenschirme" keyword, we've been unsure if it wasn't better to have the shop as the main page and the B2B page in a subdirectory.

So basically:

<code>sonnenschirme.at/subdirname = B2B page
sonnenschirme.at = main page / B2C</code>

But then again B2B generates much more revenue (at least right now). What do you guys think? I'm anxious about "just trying" because it could hurt traffic badly.
