Link Velocity: How Many Links Per Month Is Safe

Link velocity is just how fast a site picks up (or loses) backlinks, and there’s no safe monthly number Google has ever published. Speed on its own isn’t really what gets sites into trouble. It’s the pattern: a sudden, samey burst that no real website would earn by accident.

People ask me about this a lot, usually after looking at our packages and wondering if twenty links a month will get them flagged. My honest answer is that it depends on the site. I know that sounds like a cop-out, so let me explain what I actually mean.

What Link Velocity Actually Means

In plain terms, it’s the number of new links you gain in a given period minus the ones you lose. I’d count referring domains rather than raw backlinks, because a single site linking to you fifty times from its sidebar shouldn’t really count as fifty new votes of confidence.

The losing side gets overlooked a lot, and it shouldn’t. Links disappear all the time for boring reasons, and Pew Research found that 38% of webpages from 2013 were gone a decade later. So even a healthy site leaks some links every month, and the net figure is the one worth watching.

Does Google Care How Fast You Get Links?

Not in the way a lot of blog posts suggest. During a Reddit AMA, when someone kept bringing up link velocity, Google’s Gary Illyes said he’d love it if people didn’t focus so much on made-up terms like link velocity. I’d call that fairly clear, even by Google’s standards.

John Mueller has made a similar point, saying what matters is whether the links themselves are natural rather than how quickly they turn up. Google’s link spam policy reads the same way, too; it’s all about links built mainly to manipulate rankings, and speed doesn’t get a mention.

As far as I can tell, the idea goes back to an old Google patent called Information Retrieval Based on Historical Data, filed in 2003, which talks about how a document’s links might change over time. It never uses the phrase link velocity. The SEO industry filled in the gaps.

So Why Do People Still Get Burned?

Mostly because the speed tends to arrive with a very recognisable pattern attached. Imagine forty links in a fortnight, each one a guest post on a similar-looking blog, all using the same commercial anchor and all pointing at the homepage, and then nothing for three months. The pace isn’t the issue there.

That’s what bought links usually look like, and it’s exactly the sort of thing Google’s systems are designed to spot. In the mild version, the links just get discounted and stop helping. In the worse version, a reviewer sees the scheme, and you end up with an unnatural links manual action.

Now compare it with a study that goes viral and picks up two hundred links in a week from news sites, blogs, forums, and newsletters, with different anchors and mostly brand names. That’s a spike as well, but it’s the kind only genuine attention creates, and nobody gets penalised for being popular.

What a Natural Link Pattern Looks Like

In my experience, real link growth is pretty lumpy. You get quiet months, then a jump when something you published gets shared around. The links come from all kinds of sites, the anchors are mostly your name or URL or some loose phrase, and they point at lots of different pages.

So when you’re building links yourself, I wouldn’t aim for a particular monthly number at all. I’d aim to avoid a pattern that couldn’t plausibly happen on its own, which in practice means varying the sites and the anchor text, spreading links across pages, and keeping the pace fairly steady.

How to Work Out a Safe Pace for Your Site

So how do you actually set a pace? The way I’d do it uses three numbers you can pull from any backlink tool in about ten minutes. It won’t hand you a magic figure, but it’ll give you something that fits your site and your niche, which matters a lot more.

The first is your own natural rate, meaning new referring domains per month over the six months before any campaign started. The second is the same figure for the pages ranking above you, which tells you what normal growth looks like in your corner of the web.

The third comes from working out how many links you need to close the gap and how many months you’re willing to take, then dividing one by the other. If that number sits way above both your baseline and your competitors’ pace, I’d stretch the timeline and ramp up gradually.

Here’s a rough, made-up example to show the idea. Your page naturally gains about two referring domains a month, competitors gain around eight, and your gap is forty. Spreading those over six months means roughly seven a month, close to what competitors already do. Cramming all forty into one month wouldn’t be.

What This Means for the Package You Buy

This is the bit that’s actually useful when you’re buying. A lot of people choose a package by price tier or by whichever one has the biggest discount, which is the wrong way round, in my view. Start from your gap and timeline, then sanity-check the monthly number against your niche.

A few habits I’d stick to: buy monthly rather than in one big batch, spread placements across your target pages instead of piling them onto the homepage, mix up site types and anchors, and budget for the whole timeline at the start so the pace doesn’t fall apart in month three.

Honestly, budget tends to be the real constraint, more than Google. An SEO budget calculator can help you see what a sustainable monthly spend looks like, and if you’re comparing offers, our guide to choosing a link building package goes through what to look at beyond the headline price.

Watch Your Negative Link Velocity Too

Losing links deserves as much attention as gaining them, which surprises some people. In that same AMA, Illyes said lost links would generally affect pages rather than the whole domain, because those pages lose PageRank. So if an important page keeps shedding links, its rankings can slip without much fuss.

I’d track lost referring domains next to new ones every month, and if you paid for any placements, check they’re still live. Put both numbers in your monthly report, because net growth is the honest figure. Gross numbers mostly just make everyone feel good about the month.
