Since my website is still very new, its domain authority is nearly negligible or not accurately measurable by tools like Ahrefs. I’m cautious about acquiring too many high-DA backlinks too quickly, as that might trigger red flags with Google. My plan is to build authority gradually by securing one high-quality backlink per week.
The challenge is that my business, while offering superior content and development compared to competitors, operates in a very small niche in Florida. For example, the top-ranking competitor for my keyword (state specific is has a DA of only 2 and their website design is very outdated.) (National keyword ranking search only has a DA of 15)
Do you think that by paying someone to post my well-crafted blog content on high-DA (60+) websites once a week, I can boost my site’s authority to a DA of 10-20+ within a month, and eventually surpass my competitor—even though my site is still new?
I'll write this with the hopeful intent that you're trying to run a real business and want to continue to use this site in the future.
If you want 1 real link a week, through guest posting, maybe consider building a tool that you think people in your specific fire training certification business in Florida would use. An online tool, perhaps a calculator for some way a popular question in the certification process would need. Sharing that with people in relevant industries might be good. Or something along the lines of salary expectations of fire certified people are. If it starts getting traffic through a good guest posting campaign, then throw a press release at it. That's one way.
What I'm trying to say is that guest posting is not the only way to get links and hence traffic and then conversions. Maybe go for the low hanging fruits first? Have you tried to do some yourself?
Start off with citation links, and then try with forum links and then try with HARO links, and then try with guest posting. You have a natural real business site, and your competition seems low (check for other sources of traffic, maybe they're using PBNs but i doubt it) so doing the easiest links for now makes sense. These alone could bump up your site's authority if you're lucky. You'll need to build up your DA/DR to become more valuable so that some other competitor in the future would have a harder time to kick you out.
As for what you're describing, it sounds like a service you'd find here or on other platforms. Check the samples that they provide, look for links to random websites which won't be relevant to yours. Check for outbound links for casino and betting, these are also things that I'd stay away from. If you're thinking of doing this for a long time, because its your real business, then I'd suggest not going for those. If they get penalized in the future (I mean, if they're taking money for it, and are linking to anyone who pays them, then it's not really relevant to you), best case those links become worthless, worst case you get penalized. I don't think its worth it.
I think the jump to DA 02-10 or 20 in a month is risky, I think it would seem unnatural. A very high jump in rankings should be sustained. Read about link velocity, and how your traffic should also match that, so unless you can get traffic through those links to your site, its not worth it.
Maybe you can look at your content, or other keyword research tools, or look at the queries which you're getting on your GSC and try improving your content. Other ways is to use Microsoft Clarity so you can see how a user interacts with your content.
All I'm trying to say is that, links isn't everything. You're going to also need to convert your traffic when they come in.
