Bulk Backlink Checker Across Domains

WHAT IT DOES Bulk Backlink Checker Across Domains solves a common SEO and link analysis challenge: identifying which domains link to your target URLs is critical for understanding your backlink profile, but checking each page individually is tedious. This tool lets you enter a list of source URLs (pages to search) and target URLs (domains/pages to find backlinks to), then searches each source page for links pointing to any target URL. Results show which source URLs contain backlinks to which target URLs, including the anchor text used and the specific link URL. Color-coded indicators make it easy to identify results: green for found backlinks, red for no backlinks found. You can configure case sensitivity, filter results by target domain, and export the complete report as CSV or JSON. WHERE IT RUNS This extension panel runs directly inside your browser as an overlay on any web page. It works independently of any specific site and requires no additional API keys or permissions beyond the BotGentz extension. The tool fetches page HTML, parses links, and matches them against target URLs, making it usable from any browser session. HOW TO USE After installing the BotGentz extension and activating Bulk Backlink Checker Across Domains, click the extension icon in your browser toolbar to open the panel. Enter your target URLs in the first text area — these are the domains or pages you want to find backlinks to. Separate them by commas or new lines. Enter your source URLs in the second text area — these are the pages you want to search for backlinks. The preview section shows the total number of potential matches (sources × targets). Click "Check Backlinks" to begin the analysis. The tool processes each source URL sequentially with a 400ms delay, fetching the page, extracting all links, and matching them against the target URLs. Results appear with color-coded status indicators and show which sources link to which targets, including anchor text. Click "Export Report" to copy the complete dataset to your clipboard in CSV or JSON format. Click "Clear" to reset the panel. TECHNICAL OPERATION — Link Extraction and Backlink Matching This tool fetches each source page's HTML using GM_xmlhttpRequest, then parses all anchor tags to extract href attributes and anchor text. Relative URLs are resolved to absolute URLs using the base URL. Extracted links are normalized (case-insensitive option available) and matched against the list of target URLs. A match is found when the normalized link URL contains the normalized target URL or vice versa, allowing both full-page and domain-level matches. When a match is found, the tool captures the anchor text (the visible text between the and tags) and the full link URL. The tool supports configurable timeout settings and case-insensitive matching. Results are stored locally and can be exported as CSV with proper field quoting for Excel compatibility, or as structured JSON for programmatic use. A 400ms delay between source checks prevents rate limiting and server overload. THE PANEL The extension panel is fully draggable and remembers its position per site session. It snaps to the nearest edge of the browser viewport when dragged within 50 pixels of any side. You can collapse the panel to a compact title bar using the minimize button, preserving your selection state. The panel resizes vertically by dragging the bottom edge. Press the Escape key to close the panel instantly. The preview updates in real-time as you enter URLs, and the results section updates as checks complete. PLEASE NOTE This tool requires the free BotGentz extension to function. The script fetches page HTML and parses links for backlink analysis. It does not store, transmit, or log any page content, link data, or user activity. All operations are performed locally from your browser session. The tool fetches the full page HTML, which may include large pages; the timeout setting can be adjusted for slower sites. Backlink matching is based on URL containment and may require adjusting case sensitivity settings. Results may vary based on your network connection and the target server's availability. Export formats include CSV and JSON for maximum compatibility with analysis tools. The timeout and case sensitivity settings are configurable to suit different analysis needs. Some sites may block automated requests; results may be incomplete in such cases.
