WordPress Blog Interlink

About

Internal linking is one of the highest-impact, most tedious SEO tasks in WordPress. WordPress Blog Interlink automates it - insert anchor links and make targeted content replacements across many posts at once, safely, through the official WordPress REST API.
No plugin to install on your site. Connect any WordPress site with an application password and manage internal links for all your sites from one dashboard.

KEY FEATURES

Bulk internal link insertion - paste post URLs, set the anchor text and target URL, choose first / last / all / Nth occurrence
Content replacement - replace a sentence and add your internal link in one pass
Quick Paste - paste jobs in a natural 3-line or 5-line text format and run them as a batch
Bulk queue - rate-limited, retries on failure, processes large batches without hammering your server
Preview before you run - see exactly what will change before any post is touched
One-click undo - every modified post is backed up locally so you can restore it
Activity logs - full history of every change, exportable to CSV
Multi-site - manage all your WordPress sites from one place
HTML-safe - links are inserted by walking the DOM, never by blind find-and-replace; headings, captions, code blocks, shortcodes, and existing links are skipped by default

SAFE BY DESIGN

Works through the official WordPress REST API with application passwords - no FTP, no database access, no plugin
Site access is granted per site, at runtime, only for the sites you add
Credentials are stored locally in your browser (chrome.storage.local) and sent only to your own WordPress sites
