So, one of the campaigns I am running has 90 pages with missing titles. Normally I would consider this a very bad thing, BUT, the pages are product description pages. The referring pages are product listings, and the pages without titles, are small pop-ups.
For example on a bigger stage: Nike has a product page, when you click on a shoe, a small window pops up with price, description, etc. How important/ vital/ relevant is it to have titles for these pop-ups, if it is even possible.
Thank you in advance!
