Does WP automatically tag posts into the archive?

What your looking at there is a tag called “how to compliment a women”.

The first result is your tag/category page being indexed by google, which is normally a good thing. The word Archive is being added via your theme but it just means its a category/tag page that will display a list of posts. Again, this is most likely a good thing.

The second result is a page with the slug/url “how to compliment a women” that is also tagged “how to compliment a women”.

You should be able to Admin > Posts > Tags to view a full list of your tags.
