Diff, Trends and Volatility

From RankGear.wiki

RankGear's Compare workspace holds three tools for judging whether SEO work changed anything[1] . Diff compares two saved runs, Trends follows the same factors across many runs, and Volatility repeats a search to measure how much the results move on their own[2][3][6] . All three rely on stable Factor IDs so that the same measurement is compared each time[5] .

Key facts. Diff joins two saved runs by stable Factor ID, Trends reads a series of runs over weeks, and Volatility sets a noise baseline by repeating the same search[2][3][6] .

Overview

RankGear's features page describes the Compare workspace as the place to "separate real change from SERP noise"[1] . The product tour frames the question as whether rankings moved because of the user's work "or did the SERP just shift?"[4] . Each tool works from the timestamped workbooks that every run writes, described in Reports, workbooks and Action Planner, and from the run workflow described in How RankGear works.

Diff: what changed between two runs

Diff takes a before and an after workbook for the same keyword and target, aligns them by Factor ID and shows differences in three layers[2] :

The maker positions the result as the artifact that answers "what did this month of work actually do?" for a client[2] . Diff does not fetch new data, and the maker advises comparing like with like, meaning the same keyword, target, depth and provider, or "the differences reflect the setup, not your work"[2] . It also states that a change in rank between two runs "is a measured difference in the field, not proof your edit caused it"[2] .

Trends reads a series of runs for the same keyword and shows how factor correlations, deficits against the chosen strategy, entity usage and recurring domains shift across weeks[3] . The result is a table and charts with factor usage, average correlation over the period, maxima and page-one benchmarks[3] . The maker says a handful of runs is useful and more is better, provided the keyword, target, depth and provider stay consistent[3] .

RankGear describes Trends as showing how measured relationships have moved, not as a ranking forecast[3] . A rising correlation across runs is described as "a reason to prioritize it, not a promise that matching it will rank you"[3] . Correlation itself is explained in Spearman and Pearson correlation.

Volatility: the noise baseline

Volatility repeats the same search several times and measures how much the result set rearranges when nothing on the target page has changed[6] . A calm field means a rank move is more likely to mean something; a restless field means small moves are probably noise[6] . The maker recommends running Volatility before Diff and alongside Trends, and "never credit an edit for a SERP that was simply restless"[6] .

Each repeat is a SERP Volatility Sample: one capture of the results page for one keyword at one moment[7] . RankGear's glossary says samples are comparable only when provider, country, language, device, location, requested depth and completeness all match, since a change of device or city "is not volatility — it is a settings mismatch"[7] . Its worked example describes a guide that slipped from position 6 to 9 on a query where the top ten reordered between nearly every sample, suggesting churn rather than a penalty[8] .

More repeats give a steadier estimate but take longer and use more provider calls on the user's account, and a field that is calm one week can be restless the next[6] . Volatility is also a key idea in SEO testing and RankGear's Experiments.

Why stable Factor IDs matter

A Factor ID is "a frozen identifier in the form RG-FAMILY-NNN" that keeps a factor's meaning the same across workbooks, Diff and Trends[5] . The RG prefix marks a RankGear factor code, the family segment groups related factors, and the number identifies the factor within its family[5] . A factor's display name can be reworded and its position in a report can move, but its ID does not change[5] .

RankGear's glossary example is a factor renamed from "Body word count" to "Main content length" between runs; because both rows share the ID RG-CONTENT-014, Diff reports the change correctly and Trends plots one continuous line[5] . The glossary adds that an ID "names the factor but carries no score, ranking, or judgment of the page"[5] . The families are listed in the RankGear factor catalog.

Common questions

How do you compare two SEO analysis runs?

In RankGear, Diff takes two saved workbooks for the same query and target and aligns them by Factor ID to show changes in factor priority, URL ranks and optimization progress[2] . The maker advises keeping keyword, target, depth and provider the same[2] .

What is the Trends tool?

Trends reads many runs of the same keyword and shows how correlations, deficits, entity usage and recurring domains move over weeks[3] . It is not a ranking forecast[3] .

What is search result volatility?

It is how much a results page moves on its own when the target page has not changed[8] . RankGear's Volatility tool measures it by repeating the same search[6] .

What is a Factor ID?

A Factor ID is a fixed code in the form RG-FAMILY-NNN, such as RG-CONTENT-014, that keeps a factor's identity stable across runs even if its name changes[5] .
