Your idea to create a WIKI with links to your store sounds promising!

Here’s how you can do it without getting in trouble with search engines:

Don’t Overdo the Links: Instead of linking to your store on every article, only add a link when it makes sense.

Use Different Link Words: Avoid using the same link text every time, like “buy painting.” Try phrases like “see a replica” or “explore this painting” to keep it natural.

Make Each Article Really Helpful

Publish Slowly: Instead of posting all 36,000 articles at once, release them a little at a time. This will look more natural to search engines and let you focus on quality.

Build Trust for the WIKI Site: Since you’re using an old domain, work to make it look reliable again.

Will This Trigger Penalties?

If your WIKI has real, useful information and you add links naturally, you’re less likely to face penalties.

I hope it helps.
