I am beginning to create/redesign websites for local businesses. I have experience with Squarespace but have decided to learn WordPress as well. I have a job that will require a total redesign. I will be redoing a site currently in vBulletin to WordPress. The client would like to keep his current host. What is the best way of going about this? Should/Can I design the site on my host then transfer it to his? Once the new site is built, and I point the domain to that site, am I right to assume that it may take a short-term hit in search rankings? If so, is there anything I can do to avoid it?
Am I going about this the right way and asking the right questions? Anything I'm missing?
Thank you in advance!
