# Link velocity

Link velocity is the rate at which a site gains or loses backlinks over a period. No Google documentation names a safe rate, and its representatives have said the systems judge the links themselves rather than their pace. It is a metric tools sell and Google does not use.

## What a natural profile looks like

Real link profiles are bursty, not linear. A product earns a cluster of links in a week and almost none for two months, because links follow events.

| Event | What happens to the link count |
| --- | --- |
| A launch on a listing site | A dozen links and mentions in two days, then nothing |
| A piece of coverage | One good link, then the syndications and roundups that copy it |
| A tool that people cite | A slow trickle for years, the steadiest kind |
| A quiet quarter | Almost nothing, which is normal and not a signal of decline |

A chart of a healthy small site therefore looks like steps, not a slope. Tools that grade you on a smooth curve are grading you on a fiction.

## When a spike is worth looking at

- You did not earn it. A sudden burst of links from sites you have never heard of is usually a negative-SEO burst, which Google says it ignores in nearly all cases.
- Someone you hired bought them. That is a policy problem whatever the pace, and it is the one case where the disavow file exists.
- A single page took off. That is not a problem, it is the thing you wanted.

> Google neutralises most link spam rather than demoting the target. Before you disavow anything, check whether Search Console shows a manual action. Usually it does not.

## What to measure instead

1. **Count referring domains, not links** Ten links from one site are one relationship. The Links report in Search Console lists the sites; a link index lists more.
2. **Look at who, not how many** A link from a site your buyers read is worth more than fifty from sites nobody visits. Read the list, do not just count it.
3. **Track the traffic the links send** A referring domain that sends visitors is doing two jobs. Your analytics shows which ones do.
4. **Judge quarterly** Links arrive in bursts, so a month is noise. Compare a quarter with the one before it.

## Questions

### Is there a safe number of backlinks per month?

No published figure exists. Google has said its systems judge the links rather than their pace, and natural profiles arrive in bursts around launches and coverage.

### Can too many backlinks too fast hurt a site?

Earned links cannot. Bought links are a policy problem at any speed. A sudden burst you did not earn is usually ignored: Google says it neutralises such links in nearly all cases.

### What is a good link velocity for a new site?

The question has no useful answer. A new product earning five real referring domains in its launch month is doing well; earning none for two months afterwards is normal.

### Do tools measure link velocity accurately?

They measure their own index, which discovers links at its own pace. A jump in a tool’s chart often means the crawler found old links, not that you gained new ones.

### Should I disavow a sudden spike of spam links?

Almost never. Google says most sites do not need the disavow file, and that it is meant for a manual action for link spam or a history of paid links you cannot remove.
