Rank went up, But?

[SEObleu.com]

ok, I have been optimizing a sit for a while and decided to drop the flash site build an HTML site instead for obvious reasons.  But, as I was building the new site, BANG! a big jump in Google rank? How can this be, I thought out loud.  Must be all my anchor text kicking in...So, I am left with this question...Or did google pick up on my new site as I was building it.  I build it on a new DNS, then revert back to the main DNS...

Drop the HTML site and continue my link getting with the main site? Or chalk it up under something else and roll with new site.

I hope that was not to confusing

You can check if your staging has been indexed by running a 'site:' query in google (i.e. site:staging.yoursite.com). The spike in your existing site is likely due to outside factors (new links? dig in to what keywords you saw jumps in), but regardless, you should continue with the HTML site. As long as it is implemented properly, it will likely outperform the flash version in the long run.
