Search changed. Most SEO software didn't.

Google in 2026 is not the search engine we optimized for in 2019. Content depth, information value, expertise signals, semantic relationships and intent all shape what ranks — and AI has created an entirely new layer of search visibility.

Yet much of the SEO stack still revolves around the same numbers: Domain Rating. Keyword Difficulty. Backlink counts. Generic scores. Useful data — but data alone doesn't explain why something is happening, or what to do about it. Algorithm was built to work at that layer.

Every analysis shows the signals and reasoning behind its result — while the models, thresholds and calibration that produce it stay proprietary. Transparent enough to understand the decision. Proprietary enough to protect the model.

How (and why) we built Algorithm

It started as an internal SEO system. As search evolved, the questions we needed to answer outgrew the tools we were paying for. Which links actually matter? What does a page genuinely add? Does this content demonstrate real expertise? Why is one page semantically stronger than another?

So we built the analysis ourselves — tested it on real projects, changed the models when results didn't make sense, and kept the pieces that survived. Three years of internal tooling became the product you're looking at.

"The tools gave us plenty of data. They just didn't answer the questions we actually needed to solve."

What we built differently

01

Link Quality, beyond DR

Domain Rating describes a domain. It doesn't tell you whether a specific link is worth anything. We analyze the link in context: relevance, placement, surrounding links, anchor patterns, section deep-scan, PBN detection, historical signals. 30+ factors, one link-level assessment.

02

Text Audit: four audits, one pass

AI detection is one question out of many. We combine content quality, E-E-A-T signals, evidence, structure and semantic characteristics into a single report — instead of forcing you to run separate audits and reconcile them yourself.

03

Information Gain, paragraph by paragraph

Word count doesn't tell you whether an article contributes anything. We compare your content against the existing search landscape to show where you add information — and where you repeat what already ranks. Meaning-level analysis, per paragraph, with format fit and AI citability included.

04

Commercial pages, beyond content

Commercial rankings aren't won by articles. We audit what actually differs: SERP intent, feature parity with the ranking pages, schema depth and connectivity, machine-readability for AI shopping agents — and the differentiation slots nobody in the top occupies.

05

SERP-based clustering

Keywords with the same top-10 usually share intent. We cluster by real SERP overlap — so you know which queries one page can win, and where separate content is actually necessary.

06

AI visibility across 6 sources

ChatGPT, Perplexity, Claude, Gemini, Grok, Google AI Overviews. As AI search takes share, rankings alone no longer describe your visibility. We track both in one workflow.
