Hidden costs

Apps and extensions, platform fees, hosting, content re-work and internal team time are often underestimated.

Reduce risk

Start with paid discovery, phase the launch and protect SEO from day one.

Common mistakes to avoid

✕Choosing a platform on licence price instead of total cost of ownership
✕Launching a new site without an SEO redirect plan
✕Adding extensions and apps without checking performance or security
✕Leaving upgrades until peak season
