Query to generate traffic.

I have a site exactly a year ago, I publish dental clinics in major cities in the U.S. and Canada, I have organic visits by several of them but the traffic is very little about 400 monthly visits, some keywords that interested me in principle I worked badly here hiring services links, blog comments, social actions, I understand that one or perhaps more of one of the services I hired to promote these keywords were harmful because they disappeared in the search results.
In short, I want to generate some traffic and not be penalized, I saw a service here to appear for a few hours on the cover of Reddit, do not know what risk means this if I intend to grow over time?
Thank you

Which services did you use, you need to use services that work like guest post, niche edits, or high quality pbns

If I guess it's the rookie price, I thought that with so many positive comments and seniority in the forum would be beneficial but I was wrong. The service I have in mind promises a lot of traffic, which will be fleeting but traffic at last, I would not know it will be bad for my site because I do not want to fuck more. Thank you

I'd prefer not to buy such traffic boost on a site that's fairly alive. There may be better ways to hike up UVs.

What I will do from now is buy a link that is offered here that has a high cost but I understand will be good in the long term because it will be one per month, this to improve the SEO, in terms of traffic seduces me that offer Reddit but I prefer if it is harmful to leave it until it has a greater traffic and is not perceived as a bad action.

Before investing any more money into links I'd make sure to learn how to use them. If SEO would be so easy like just coming to BHW, purchasing some links and ranking everyone would do it and people wouldn't stop their BHW journeys after 1 month.

Also, make sure that the niche you're going after is well worth it. You can spend money, rank it and at the end not get profit. That's like = 0 even though you get some experience but better to figure out earlier.

If perhaps the niche is more complicated than I originally understood, the main keywords are dental office and dental office near me. I understand it is a subject where you invest and therefore I could make some $, also I would like to monetize when I improve in the SERP contacting the dental clinics to offer a space. I appreciate suggestions dental-office dot org

If someone with experience has a minute and visualize the site I appreciate suggestions. dental - office dot org
