Hi Jazee,

I would say that, while there are advantages of having the two lines of business on the same domain (such as having to build domain authority for one website instead of two), from an SEO perspective your optimisation tactics will differ between the two business services.

For example, your link building for the Wedding Planners side of the business will likely require different strategies to Convention Logistics. For this reason, if it were my company, I would keep them on separate domains. There would also be other considerations, such as your content strategy and whether you will have a blog for both, one for each, or no blog at all.

This does depend on factors such as your SEO plans for the businesses, how closely linked the two sides are, how much you can invest in SEO, whether your domains are both starting from scratch (i.e. no domain authority).

In the long run you'll have one website optimised for Wedding Planners and another optimised for Convention Logistics, which in my opinion is better than one website that is split between two different industries.

Hope this helps.

Best regards,

James
