Evidence Library

Proof, not opinions.

Every recommendation backed by evidence. Every decision supported by data. Full-text search across competitor intelligence, content gaps, ranking correlations, and more.

Blind trust is not a strategy.

You wouldn’t make a business decision without evidence. Why should SEO be any different?

Recommendations without reasoning

Most SEO tools tell you what to do but never explain why. You’re expected to trust the algorithm and implement blindly. When it doesn’t work, you have no idea what went wrong.

No audit trail

Six months from now, can you explain why a specific change was made? Without an evidence trail, every past decision is a black box. That’s a problem when leadership asks questions.

Data scattered everywhere

Competitor data in one tool. Ranking data in another. Content analysis in a spreadsheet. Connecting evidence to decisions requires manual work that never actually gets done.

Search everything. Find anything.

Full-text search across every piece of evidence Korvex has ever collected. Type a keyword, a URL, or a topic and see all relevant competitor data, content gaps, ranking correlations, and SERP feature insights — ranked by relevance and recency.

No more switching between tools to piece together the picture. Everything is in one searchable library, automatically categorised and scored.

Every recommendation tells you why.

Korvex doesn’t just tell you what to do. It shows you the evidence that led to each recommendation. Competitor analysis, statistical correlations, content gap data, SERP feature opportunities — all linked directly to the action item.

The confidence score reflects how much evidence supports each recommendation. More evidence means higher confidence means better prioritisation. No guesswork. No opinions. Just data.

Six types of evidence. One library.

Every dimension of SEO intelligence, collected automatically and categorised for instant retrieval.

Competitor Intelligence

2.4K items

What your competitors are doing that you’re not. Content strategies, keyword targeting, SERP feature ownership, and page-level analysis.

Content Gaps

1.8K items

Missing entities, topics, and sections that top-ranking pages cover. Identified by comparing your content against the top 10 results.

Ranking Correlations

340 items

Statistical analysis across your portfolio showing which on-page factors correlate with higher rankings. Based on real data, not assumptions.

SERP Features

890 items

Featured snippets, People Also Ask, knowledge panels, and other SERP features you could own. Evidence of what format search engines prefer.

Entity Analysis

1.2K items

Knowledge graph entities, topical authority signals, and entity coverage gaps. Evidence of what search engines consider authoritative for each topic.

Historical Performance

5.6K items

Past ranking changes, traffic patterns, and the actions that preceded them. Evidence of what has worked before and what hasn’t.

Full accountability for every decision.

Every recommendation is tracked from creation through deployment to outcome measurement. Six months from now, you can look back at any change and see exactly why it was made, what evidence supported it, when it was deployed, and what impact it had.

This isn’t just good practice. It’s how you build trust with clients, justify your strategy to leadership, and learn what actually works for your specific site.
