Rather foolishly, I have been developing my site on a live server (with VCS don't worry), kind of using it as a portfolio / show off piece. It is far from finished.
Recently, I noticed that Google started to spider it, including some of the debug data accessible across the site as it's in 'debug' mode. I'm not sure of the future effects this will have on my site when it is finally released - especially as some pages are just erroring out while I develop and there is some gobbledygook/dummy/blank data on a few pages.
SEO wise, what are the best steps to take to not incur any present or future Google penalty? One thing I thought of was to possible disallow spidering in robots.txt, put up a splash page and then setup a decent sitemap when the site is live again.
Regardless I am going to setup a development domain somewhere but would like to know the safest way of migrating it down.
