I have various wordpress websites that generate their content dynamically via an API.
As the sites have grown they has slowed down considerably. I am in the process of getting the sites and their hardware looked to see how we can get around this bottle-neck, but in the mean time I would like to try to keep all visitors on site so they wait for pages to load.
My idea is to have a page that loads instantly when the visitor visits the site and notifies them of the site slowness, that we know there is a problem, and ask them to please wait while the page renders.
My question is regards to how best to achieve this in Wordresss without falling foul of any Google penalties. I don't want the notice to be indexed (or even seen by Google if possible) and I don't want it to interfere with any existing page rank etc.
How best to proceed?
Thanks for any help with this
