If you use the templates, do you need Wrangler?

Hello,
I am able to create Workers sites just through the Editor. I haven’t used Wrangler to give any instructions. However, the sites aren’t indexing. So is using the Wrangler CLI correctly a prerequisite to making sites index or can I just continue making workers sites with the supplied templates? Thank you.

Indexing in Google?

Thank you. Yes, indexing in Google. But I haven’t used the Wrangler CLI at all to make these sites so I’m wondering if I missed an important step.
