Question for SEO Experts: Is My 68K Backlink Strategy Safe for Long-Term SEO?

Hi everyone,

I'd like to get some advice from experienced SEO professionals who have been using RankerX and GSA SER for large-scale link building.

I'm currently working on a website with the following SEO metrics:

• Authority Score: 42
• Organic Traffic: 262.4K
• Organic Keywords: 67.6K
• Referring Domains: 3K
• Total Backlinks: 68.5K

My current link-building strategy is entirely automated:

• Tier 1: Ranker X
• Tier 2: GSA SER, pointing to my Tier 1 backlinks

My questions are:

• With approximately 68.5K backlinks from 3K referring domains, is this backlink profile reasonably safe for long-term SEO?
• Is using RankerX for Tier 1 and GSA SER for Tier 2 still an effective strategy in 2026?

Your setup is the one i run, RankerX on tier 1 and GSA SER behind it, and it still works in 2026. 68K links from 3K referring domains on a site with 260K traffic doesnt worry me on its own. What I would check is where everything points. RankerX properties link to the money site and GSA only hits the RankerX properties, that is the safe version. If any GSA project has the money site as a target, even an old one you forgot, fix that first because that is what gets sites hit. Second is the tier 2 targets. I stopped scraping them and buy them, ser verified lists and ser power lists at the moment, both have dead targets and I filter on import, but it costs less than the proxies did.

SER Power lists are simply not good enough. I tested them just a few days ago, and out of 700,000+ unique targets, I managed to get only around 3,400 verified links. For comparison, that's roughly what I can get from my own identified list in the first hour alone.

The problem is that they're selling lists that were verified who knows how long ago, and they keep recycling essentially the same targets over and over again.

If you don't believe me, download all their files daily and compare how many genuinely new, unique sites are being added. You'll probably find 1,000–2,000 at most per day.

So what exactly are people paying for when they purchase a 6- or 12-month subscription if 99% of the list stays the same?

The whole point of paying for a service like this should be getting fresh, working, regularly maintained and re-verified targets, not constantly recycling outdated data.

Even someone running churn-and-burn campaigns would struggle to achieve a high VpM with these lists, simply because they're not properly cleaned, maintained, or re-verified.

A massive list means absolutely nothing if most of the targets are dead, outdated, or no longer working.

The most value comes from referring domains, and that's how most of my sites work. Since backlinks are dying, it's fine to build a few multiple links from the same referring domains to keep your new and lost counts up. But the real value is mostly in referring domains. And don't worry, big G is way better than it used to be, so it won't punish you much if you mess up, just ignore the noise. Keep doing what you're doing. Consistency matters more than anything.

Keep doing what you're doing, but I'd lower building tier 1. Instead, build 3 or 4 links from self hosted sites and then blast with GSA SER. Try to keep the referring domain count steady. The chart should show a gradual upward trend in referring links.

You should have included a bit more in your screenshot, as the domain's age is also an important criterion for evaluation.
