Hi @bwaldon4, hope you're having a good weekend!
Can I make certain pages not indexed by search engines?
Yes, you can add those pages to the robots.txt file (in the site settings page in the Dashboard). However, please keep in mind that once you add them there, Google can cache those URLs for a long time, so if you decide to later index the pages, it may take a while for those pages to start showing up in search results.
If I upgrade is there a limit to the number of pages I can build?
Yes, each site is currently limited to 80 pages, or 100 pages if you're on our Teams plan.
Can I publish a single page without publishing the entire site?
Currently, no - Webflow publishes the entire site in one single operation.
Are there any future plans for eCommerce?
Yes, but we haven't announced anything concrete. Check out the Paystand integration blog posts for an example of how to do this with external services: www.paystand.com/blog/webflow-paystand-adding-responsive-payments-and-stores-directly-to-your-website/
Are there any future plans for blogging?
Yes, but we unfortunately don't have any solid dates or timeframes yet.
