Citation Flow is an authority metric developed by Majestic to estimate how influential a page or an entire domain is on the web, based solely on the number and quality of inbound links. The value is expressed on a scale from 0 to 100, where higher numbers indicate a greater ability to pass authority through links. Unlike other metrics that assess the overall standing of a resource, Citation Flow focuses on the number of citations received, weighting them by the authority of the sources that generate them.
Together with Trust Flow, Citation Flow makes up the best-known pair of indicators from the Majestic service. While Trust Flow measures how trustworthy a site is and how close it sits to sources considered authoritative, Citation Flow quantifies the volume and strength of citations. Reading the two values together lets you tell a natural, solid link profile apart from one built artificially, giving SEO professionals a fuller picture of a domain’s quality.
How the score is calculated
Citation Flow is calculated with an iterative mathematical model that assigns each page a starting score, then updates it based on the links it receives. Each link passes part of its own authority to the destination page, and the process is repeated several times until it reaches a stable value. The final result is normalized on a logarithmic scale from 0 to 100, so that resources of very different sizes can be compared.
One important point is that Citation Flow does not clearly separate high-quality links from low-quality ones: it tends to reward the volume of citations above all. For this reason, a site with many backlinks, even from mediocre sources, can get a high Citation Flow while keeping a low Trust Flow. The gap between the two metrics is often the most useful signal for anyone analyzing a link profile.
The other authority metrics compared
Several metrics are used in the industry to assess a site’s authority. Each one applies its own criteria and produces values that cannot be converted directly into one another. Understanding the differences helps you read the data correctly and avoid misleading comparisons.
Citation Flow and Trust Flow
Trust Flow is the natural counterpart to Citation Flow. While the first assesses the trust placed in a domain based on how close it is to sources considered reliable, the second measures the strength and number of citations. A balanced profile shows similar values across the two metrics; a marked imbalance suggests unreliable links or artificial link building.
Citation Flow and PageRank
PageRank, introduced by Google, was the first algorithm to model a page’s authority as a property passed on by inbound links. Citation Flow draws on this logic but is not a ranking factor used by search engines: it is a third-party analysis tool. The two metrics do not coincide and cannot be compared directly.
Citation Flow and Domain Authority
Domain Authority, developed by Moz, combines many signals, including the number of linking domains and their quality. Citation Flow, by contrast, focuses on citations and how they spread. Both offer an estimate on a 0–100 scale, but the calculation methods and data sources are independent, so the values are not interchangeable.
Citation Flow, Trust Flow, PageRank and Domain Authority
| Metric | Provider | What it measures | Scale |
|---|---|---|---|
| Citation Flow | Majestic | Volume and strength of citations | 0–100 |
| Trust Flow | Majestic | Reliability of linked sources | 0–100 |
| PageRank | Authority passed on by links | 0–10 | |
| Domain Authority | Moz | Predictability of ranking | 0–100 |
| Authority Score | Semrush | Overall quality of the profile | 0–100 |
Reading the score without misreading it
Citation Flow should always be read in relation to context and the other available metrics. A high value does not automatically mean good rankings, just as a low value does not rule out a quality site. Here are a few useful steps for a correct analysis.
- Compare Citation Flow with the Trust Flow of the same domain to spot any imbalance.
- Check the ratio between the two metrics: similar values point to a more natural link profile.
- Analyze the distribution of inbound links, separating authoritative sources from weak ones.
- Check the trend over time, because a sudden increase can signal suspicious activity.
- Compare the domain with direct competitors in the same industry and of the same size.
- Consider the context: a niche site can have lower values than general-interest portals.
- Use the metric as a trend indicator, not as an absolute measure of quality.
- Combine the figure with other tools to get a more reliable assessment.
Frequently asked questions
What exactly is Citation Flow?
It is a Majestic metric that estimates the influence of a page or domain based on the number and strength of inbound links, expressed on a scale from 0 to 100.
Does Citation Flow affect rankings on Google?
No, it is not a ranking factor used by search engines. It is a third-party analysis tool that helps assess link popularity, not determine positions in the results.
What is a good Citation Flow value?
There is no universal threshold. The value should be compared with that of competitors and with the Trust Flow of the same domain: the balance between the two metrics matters more than the absolute number.
Why can Citation Flow be high and Trust Flow low?
This imbalance usually points to many links coming from unreliable sources. Citation Flow rewards the volume of citations, while Trust Flow penalizes low-quality sources.
How can I improve my site’s Citation Flow?
By earning links from authoritative sites relevant to your industry. Growth should be gradual and natural, avoiding aggressive strategies that can create imbalances between the metrics.
Is Citation Flow reliable as the only indicator?
No, it should always be paired with other metrics and a qualitative analysis of the links. Looking at it in isolation can lead to misleading conclusions about the real health of a backlink profile.
