In order to facilitate updating the meta tags across a dozen or so webpages in one site, I want each page to call a script that will use document.write() to write the meta tags into the header.

Will this work for robots and getting my site indexed? Does the meta info get collected before any script is executed? (If it does, then my idea won't work).

Any experts on this matter, I would love to hear from you!

Thanks everyone.
