The new symbol system references classic “weather” images:
- The thunderstorm icon – dark gray cloud with lightning – indicates that the data detected by SEOZoom is reporting very high activity, with relevant changes within the SERPs.
- The rain icon – light gray cloud with raindrops – indicates high activity, above the historical average.
- The sun icon tells us that Google activity is regular and results do not deviate from the average.
- The clear moon icon indicates moderate activity, lower than the standard fluctuation rate.
On the graph, however, a four-colored dot system has been introduced:
- Red for very high activity.
- Yellow for high activity.
- Blue for regular activity.
- Light blue for below-average activity.
In addition, two colored bands also appear in the graphs, which visually identify the standard average of variations on the SERPs: the green colored one encloses precisely the average recorded level of activity, while the yellow one embraces variations toward more intense movements. Also added is the “G” symbol along the x-axis, indicating times when official Google updates have been released, to better frame the variations.
