I have a client who offers multiple services, the current website is already huge because they have added on so many new offerings in the last year and want everything above the fold. As I am building out the sitemap for a re-design, they continue to add more services. (HVAC, Plumbing, Solar, Windows, Electrical) I am working on a sitemap for a re-build, but I am still well over 100 pages deep with huge menu's. **My question is what are the SEO pros/cons of breaking the site up into multiple websites? **
