Pixel rank tracking
Every rank tracker reports an integer from one to ten. It is a tidy number, and since AI Overviews arrived it has stopped describing what a searcher sees.
Ordinal rank counts results in the organic list and ignores everything around it. A listing ranked first can sit under four paid ads, an expanded AI Overview and a local pack. On a desktop screen that pushes Organic #1 below 1,180px. On a phone it lands below 1,640px, several full screens of scrolling away. The tracker still says position one. Your click-through rate says otherwise, and the gap between those two signals is exactly where traffic disappears unexplained.
Computed from the same layout constants as the homepage simulator. Orange bars cross the depth threshold.
Each check loads the results page in a real browser at fixed viewports, 1440 × 900 for desktop and 390 × 844 for mobile. We read geometry from the layout engine rather than guessing from markup. The primary figure is Y-depth: the distance in CSS pixels from the top of the page to the top edge of the first organic container.
fold_ratio = y_depth / viewport_height
Around it we store the fold ratio, the share of the viewport your listing occupies, and an ordered list of the modules sitting above you. Because we keep the raw geometry, every metric can be recomputed when Google changes a template.
Scrolling is cheap, but attention is not evenly spread. Eye-tracking research has long shown that results visible without scrolling collect a disproportionate share of clicks, and each further screen sheds more readers. That does not make the fold a hard wall; it makes depth a continuous cost. Pixel tracking treats it that way, scoring every result by how far it sits from the first screen rather than by a binary above-or-below flag.
Mobile deserves its own line in every report. Narrow screens stack modules vertically with no sidebar to absorb them, so the same results page is roughly 40% deeper on a phone than on a desktop in our fixtures. Reporting one blended rank hides the device where most of your searchers sit.
| Sample query | Rank | Desktop | Mobile | Verdict |
|---|---|---|---|---|
| emergency plumber near me | #1 | 1,096 px | 1,512 px | Below both folds |
| best crm for small teams | #1 | 604 px | 988 px | Visible on desktop only |
| how to refinance a mortgage | #2 | 1,248 px | 1,702 px | Past both thresholds |
| buy trail running shoes | #1 | 356 px | 612 px | Above both folds |
| personal injury lawyer | #1 | 1,184 px | 1,644 px | Past both thresholds |
Pixel depth earns its keep as a delta. When depth jumps by more than 150 px between two checks while ordinal rank holds, something above you changed: an ad block grew, an Overview expanded, a pack appeared. We name the module that moved and alert you within the hour on plans that check hourly.
Pair that with Search Console impressions and you can separate a ranking loss, which you fix with content and links, from a layout loss, which you answer with different formats, entities and local assets. The two problems need different budgets, and until now they shared one number. Compare plans to see which check frequency fits.
