Yes, I do but not Wikipedia. Locate other popular authority websites related to your niche that are not direct competition for your keywords. Interesting.

It doesn't get almost any benefit from the root. Glad you found it useful Yep! Those are very popular mess ups. Glad you like it. Same here. Flag is definitely a possibility in that scenario. Thank you too. I'm not that optimistic but now I can simply send them here You make me blush Might come in handy if someone asks. (someone always does) Glad you like it.

Yes, I would ideally transform it to Scenario #1. Making it contextual. I'm glad you find it useful. Build a few, quality, strong ones instead of an army of weaklings.
