ZA – Zoom Authority (SEOZoom)
Zoom Authority is a proprietary SEOZoom metric that estimates the authority of a website, with a numerical value on a logarithmic scale from 0 to 100.
The signals taken into consideration by Zoom Authority are:
- Traffic from search engines
- Trust (trust shown by Google toward the website in question)
- Stability (how stable the organic ranking of the website is)
- Opportunity (how much the website can grow in the months ahead)
Specifically, Zoom Authority is composed of three metrics:
- Zoom Opportunity (ZO)
The Zoom Opportunity helps identify opportunities for a website to grow based on organic ranking, with a numerical value ranging from 0 to 100 on a logarithmic scale. Specifically, it answers the question, “How likely is the site to improve ranking on a scale of zero to 100?” To identify opportunities, the quantity and quality of keywords not yet on the first page and the likelihood that they might someday reach it are analyzed.
- Zoom Stability (ZS)
Zoom Stability represents the value, expressed numerically from 0 to 100 on a logarithmic scale, of the stability of the examined site’s organic ranking; it answers the question, “How stable is the site’s organic ranking from zero to one hundred?” Assessing a website only by its traffic would be superficial and biased, which is why Zoom Stability was provided, which instead assesses the stability of this traffic.
- Zoom Trust (ZT)
Zoom Trust numerically estimates on a logarithmic scale from 0-100 how much Google is trusting the site in question, rewarding its pages with visibility positions over competitors or, conversely, preferring the content of other sites. To be precise, then, the ZT value answers the question, “How much does Google trust this site from zero to 100?”
Compared to other common metrics, ZA does not take into account the number and (assumed) quality of backlinks, traffic volume or other “manipulable” signals, but is based on empirical observation of how Google behaves toward a given site.
This does not mean that it is perfect or infallible, but that it certainly offers a fairly reliable and useful snapshot of a site’s value, because it looks at key aspects such as organic traffic, engagement and growth opportunities.
To make the metric more neutral, the ZA is created from simple observation of SERPs and Google’s liking of the site, and it is also constantly evolving and adapting with respect to Google’s algorithmic updates.
