I'm hoping someone here has seen this before.

While reviewing our organic traffic in Analytics Plus, I noticed that a large number of visits are showing "(not set)" as the landing page. We have hundreds of indexed product and category pages, so I expected those URLs to appear instead.

I checked the obvious things like indexing and tracking, but I still can't figure out whether this is an Analytics Plus issue or something on our website. The biggest problem is that I can't tell which pages are actually driving our organic traffic, so it's making SEO decisions much harder.

Has anyone dealt with this before? If so, what was causing it? I'm trying to figure out whether this is something I can solve myself or if it's time to bring in an ecommerce SEO agency to take a proper look. I'd really appreciate hearing what worked for you.
