SEO Tool Backlink Change Alert Badge

WHAT IT DOES

This script scans SEO tool dashboards—Ahrefs, SEMrush, Moz, Majestic, and others—for backlink data and displays a floating badge panel showing changes in your backlink profile. It extracts metrics including new backlinks, lost backlinks, net change, referring domains, domain authority, and total backlinks. The panel shows color-coded indicators: green for gains, red for losses, yellow for no change. A summary grid displays key metrics at a glance, and a "change since last check" indicator shows how your backlink profile has evolved since your previous visit. Set custom alert thresholds to receive browser notifications when new or lost backlinks exceed your specified limit. Export all historical backlink data as CSV for reporting or analysis. All data is stored locally per domain for persistent tracking.

WHERE IT RUNS

Works on any SEO tool dashboard that displays backlink metrics—Ahrefs Site Explorer, SEMrush Backlink Analytics, Moz Link Explorer, Majestic, or any page with backlink data. The script scans page content for numeric metrics regardless of the specific layout, making it compatible with most SEO tools.

HOW TO USE

The panel appears automatically when you visit a backlink dashboard. It detects available metrics and displays them in a summary grid with New, Lost, and Net changes. Additional metrics like Referring Domains, Domain Authority, and Total Backlinks appear below. The "Since Last Check" indicator compares the current net change against your previous snapshot, showing how your backlink profile has changed between visits. Set an alert threshold (default 5) and enable notifications to receive browser alerts when new or lost backlinks exceed the threshold. The History section shows your last 10 snapshots with timestamps and key metrics. Click "Export CSV" to download all historical backlink data. Use "Clear History" to remove all stored snapshots for the current domain.

TECHNICAL MECHANISM: MULTI-PASS BACKLINK METRIC EXTRACTION WITH CHANGE DETECTION

The script uses a comprehensive detection strategy. First, it scans the page text for common backlink metric patterns using regex patterns for "new backlinks," "lost backlinks," "net change," "referring domains," "domain authority," "URL authority," and "total backlinks." Second, it scans all tables on the page, looking for label-value pairs where the label matches backlink-related keywords (new, lost, gained, referring domains, DA, UA, total) and extracts numeric values from adjacent cells. Third, it searches for elements with metric-related class names (metric, stat, value, number, count, data), checks the text content for numeric values, and uses the parent element's context to determine the metric type. The script extracts all metrics as numbers, then calculates net change if not directly provided. Each snapshot is stored with a timestamp and all detected metrics, capped at 30 entries per domain. The "change since last check" indicator is calculated by comparing the current net change against the previous snapshot's net change. The alert system triggers GM_notification when new or lost backlinks exceed the user-defined threshold (default 5). The export function generates CSV with all historical snapshots including dates, new/lost/net backlinks, referring domains, and domain authority.

THE PANEL

The backlink change alert appears in a draggable, resizable panel that remembers its position per site. The panel shows a summary grid with New, Lost, and Net metrics, followed by additional metrics like Referring Domains and Domain Authority. The change indicator shows how your backlink profile has shifted since the last visit. The history section shows recent snapshots in a compact list. Drag by the header to reposition, collapse to a compact icon with a click, and resize using the bottom-right corner. The panel snaps to screen edges for tidy placement and closes with the Escape key. All settings—alert threshold, notification preference, and panel position—persist per website using GM_setValue, so your view returns exactly as you left it.

PLEASE NOTE

This script requires the free BotGentz extension to run. Backlink detection relies on the page displaying metrics in a parsable format—some SEO tools may use non-standard layouts that prevent automatic detection. The script does not access your SEO tool account data beyond what is visible on the page. All data is stored locally in your browser via GM_setValue and never transmitted. The script can only detect metrics that are displayed on the current page; if your SEO tool uses lazy loading or pagination, you may need to ensure all metrics are visible. Notifications require the GM_notification grant and will only appear when the panel is closed or the page is in the background.
