Welcome to the Q&A Forum

@KleerVue do you actually have two physical locations or do you simply service the second city?

Are you referring to claiming your Google Business Profile?

It all depends on your current marketing priorities and then identifying the greatest potential opportunities that have the lowest hanging fruit. Would be happy to share additional thoughts and high-level direction anytime.

I would not no-index. Typically it is more effective to use a canonical link from the secondary content to the main page you want the traffic directed to.

Keep in mind it's not just the number of backlinks but the relevancy and quality of those links. Analyze the profiles of the pages you are competing against to start.

Is it truly cannibalizing or is the combined traffic increasing overall website traffic? Should be the first thing to consider before identifying the appropriate solution.

Is there a specific link you feel is spammy? Have you considered disavowing?
