PVI scores expose passages ripe for optimization, unlocking 12% average traffic lifts while shielding your positions from feature-snippet poachers.
Passage Visibility Index (PVI) quantifies the likelihood that a specific content block on a page will trigger Google’s passage ranking and surface independently in SERPs. Tracking PVI lets SEOs pinpoint and upgrade profitable passages—tightening headings, entities, and answer density—to capture incremental traffic and featured-style visibility without rewriting whole pages.
Passage Visibility Index (PVI) is a proprietary or in-house scoring model that estimates how likely a discrete block of copy—usually 40-250 words—will be extracted by Google’s passage-based ranking system and shown as a stand-alone result. Think of it as a “micro-CTR forecast” for individual paragraphs, not entire URLs. High-PVI passages can win incremental impressions without the budget drag of net-new content production, making the metric a line-item in content P&Ls and monthly traffic forecasts.

The Passage Visibility Index measures how often discrete sections of a page (paragraphs, lists, sub-sections) earn their own rankings or snippets, independent of the page’s primary position. A traditional Visibility Index aggregates ranking signals at the URL level. Long-form articles naturally contain multiple topical sub-sections; Google’s passage ranking can surface those sections for long-tail queries even when the page itself is not strong enough to rank highly. As a result, a niche blog can accumulate passage-level impressions and clicks—boosting its Passage Visibility Index—without seeing equivalent growth in URL-level visibility or traffic.
Google relies on clear structural cues—especially heading tags—to understand and isolate passages. Replacing semantic headings with bolded text blurs section boundaries, making it harder for the algorithm to interpret distinct passages worth ranking. The corrective action is to reinstate proper H2-H3 tags (or at least add aria-level headings) while preserving the desired styling through CSS. This restores semantic structure without sacrificing design, helping Google re-identify passages and recover passage-level visibility.
The Passage Visibility Index growth indicates Google is already recognising and ranking discrete sections, but the low CTR shows those snippets are not compelling enough to earn clicks. Meanwhile, the substantial backlink gap is limiting overall page authority, which suppresses both URL-level rankings and the potential reach of passage results. Therefore, backlink acquisition should take priority to lift domain authority. In parallel, refine meta descriptions and snippet copy to improve CTR, but large-scale passage tweaks will bring diminishing returns until authority improves.
1. Landing-page conversion rate: If many passage clicks land deep within an article (e.g., a frosting tip section) rather than at the top of the recipe, users may skip affiliate links or ads, depressing revenue. Low conversion indicates a need to place CTAs near passage-ranked sections. 2. Scroll depth or engagement time on passage-landed sessions: Short dwell time suggests the extracted passage fully satisfies intent, leading to pogo-sticking. Adding internal links or a jump-to-recipe button near those passages can channel users toward monetised content. Together, these metrics clarify whether the issue is intent mismatch or monetisation placement, guiding targeted optimisation.
✅ Better approach: Tag and track each distinct answer block (e.g., H2–H3 + 150-300 words) as its own unit in your data warehouse. Attribute impressions/clicks from passage snippets separately from full-page SERP clicks to see what actually drives visibility.
✅ Better approach: Add clear heading hierarchy, logical anchor links, and schema (FAQ, HowTo) so Google can segment the passage cleanly. Audit DOM depth and reduce boilerplate that dilutes the target block.
✅ Better approach: Map one primary query intent per passage, then write 100-200 words that answer it completely once. Use semantically related terms, not repetitive exact-match phrases. Validate with a TF-IDF or embedding similarity tool.
✅ Better approach: Create Looker Studio or BigQuery alerts keyed to GSC URL Inspection → Rich Results → ‘Detected Passage’. When the flag disappears or impressions dip >20%, trigger a content QA review before the whole page’s traffic suffers.
