I would suggest you go with a city-specific page for each service; this is the best strategy that fully works. Search engine spiders analyze the page and serve those pages which are the best in their database around that location. Let's say, my domain has services under profitparrot.com/services, you can see this is not the location-targeted page as it generally serves. While I have another page, https://profitparrot.com/seo-services-in-abbotsford/, where you can see I am targeting the location in my page URL and content. This clarifies the search engine about this page is for a specific location and I have to serve this page when someone searches for Abbotsford SEO but within that specific location. Remember, location is the main factor, you have to show the location in every aspect.

Same with me. I was creating backlinks for Profit Parrot, Ottawa Insulations and Vanity Roofing but they are not indexing. I tried some free tools but they didn't work.
