404 error-old products

[Takhara]

Hi,

I have changed the name of many of my products and in some cases deleted them altogether from my store. I didn’t do any redirects.

Google console now shows a lot of 404 errors. Is there anything I can do to fix these? Is there a way for me to remove the old URL’s entirely?

In future, what is best practice if I change or delete a product title?

Thanks
