The main indicators of the quality and authority of the site - DR,TF,CF and DA,PA

These indicators of project quality are conventionally considered the most common metrics used by most webmasters. All popular indicators are associated with different SEO platforms.

It is vital to understand that no unofficial metric can be guaranteed to indicate progress or poor results in a search engine. For example, when PageRank was active in Google, low PR proved the weakness of the project. And the conditional Domain Authority from Moz is only a value judgment.

If you look at the help section of any search marketing platform, you can find only basic information about the metric calculation model. Accordingly, even experienced optimizers won't be able to conclude that the formula is perfect because it is kept secret.

?Ahrefs

The search marketing platform has been on the market for many years and offers several metrics to evaluate the quality of both - the entire domain and individual pages. Webmasters usually use them to check donors before posting links.

The Ahrefs help section provides information on the main features of all metrics. In particular, Domain Rating uses the formula of the original PageRank with some differences.

Domain Rating (DR)

The DR metric measures the strength of a link profile on a logarithmic scale. The minimum value of Domain Rating is 0 points, and the maximum is 100. The indicator was created so that webmasters can quickly assess the quality of the site in terms of link mass.

DR is often included in the list of indicators of donor quality. The metric can be found in the interface of many link-buying exchanges. When making the final decision on the placement of links, the value of Domain Rating is usually decisive.

Domain authority is a complex metric. To calculate it, Ahrefs algorithms focus on both the quantity and quality of links. That is why it has not lost popularity for many years.

Flow of Trust (TF)

The flow of trust shows the quality of donors linking to the site. Most optimizers think that a project is not worthy the attention if its TF is less than 15. Although, each webmaster may have their standards.

With the help of Trust Flow, you can evaluate the power of the link mass of a site and a separate page. The metric is more informative compared to that from Ahrefs and other services.

Citation Flow (CF)

Citation flow has nothing to do with link quality. It is calculated only by taking into account the number of links. The more backlinks a site has, the higher its CF will be. From this, we can conclude that Citation Flow is not an indicator of quality.

Under ideal conditions, when links generated organically, a high citation flow value can be considered an indicator of authority, but the ease of buying links negates this. Therefore, CF can only be assessed in combination.

TF/CF ratio (Trust Ratio)

Trust Ratio is a metric that is calculated as the ratio of Trust Flow and Citation Flow. High-quality domains considered to have a TR of up to 1.8. These are the figures given by the reputable service Domaining LTD.

Majestic recommends choosing donors who have Trust Flow much higher than Citation Flow. It indicates the quality of the reference mass of the project. Such links will bring the maximum benefit for external optimization.

Moz

The search marketing platform is in demand on par with Ahrefs and Majestic. Some site owners believe it provides more informative data than the main competitors.

Moz offers webmasters two main project quality metrics: Domain Authority and Page Authority. They are used to decide on building reference links with selected projects.

Domain authority (DA)

DA is calculated on a scale from 1 to 100. The metric measures how well a site can rank in Google search results. The index takes into account all pages of the domain, so it can only be navigated in the context of the entire site.

Domain authority is calculated using the Link Explorer index and dozens of individual factors. The machine learning model allows you to quickly adjust the value as new data becomes available.

Page authority (PA)

PA works similarly to domain authority but in the context of a specific page. The more points URL scores, the higher the chances of ranking well in Google search results.

Authority is calculated on a logarithmic scale. That is, it is much easier to raise the rating from 10 to 20 than from 90 to 95. The calculation algorithm is constantly updated, so the numbers can change quickly.

Metrics from Moz, Ahrefs, Majestic, and other services are useful. But to get a complete picture of a specific project, it is better to use it in combination. If a site gets enough scores on multiple platform versions, it can be considered quality.
