Publish Season to Web

Web beginner here - so forgive the open-ended nature of this question...

We are trying to publish the basics of our season to the website, and getting no content to show up.  We don't use TNEW but rather an outside web developer, and they've informed Marketing and I that the web page we're working on is pulled entirely from Tess.  

I started with just mimic-ing last year's set up, by adding a 'Display on Website' keyword on the Productions (when I removed this keyword from the old perfs, they came down, so I thought this might be the ticket), Production Season, and Production level, updated the "Publish Web Date" and the same criteria last year on the Content page that are marked as "Use Web API" in System Tables .

Last year's perfs had no Publish to Client or Publish to Web dates plugged in in the Perf pages, but I tried adding today in the Publish to Web section - still no luck.

I know this is fairly custom org to org, but I'm hoping there might be a magic check box I'm just missing... On the Season level?

Any help appreciated!
