No, and any tool that promises guaranteed indexation is misleading you. Mass Indexer submits your URLs to the Google Indexing API, which tells Google to crawl those pages. The decision to index them rests entirely with Google, based on content quality, site authority and technical compliance.

Yes, completely free. No paid tiers, no usage caps, no subscription. The tool is developed voluntarily. Donations help fund ongoing development but stay entirely optional.

Google's Indexing API allows up to 200 URL submissions per day per Google Cloud project. Mass Indexer respects this quota automatically. For larger sites, you can split submissions across multiple days or use several API projects to increase throughput.

Mass Indexer accepts plain CSV files, one URL per line, along with sitemap XML files. This makes it directly compatible with the export formats from Sitemap Generator and most CMS tools.

You need a Google account with ownership or full access to the target properties in Google Search Console. The Indexing API relies on OAuth authentication. Mass Indexer walks you through it on first use.

Currently, Mass Indexer is built specifically for the Google Indexing API. Support for other search engine indexing APIs may come in a future version.

Sitemap Generator crawls your site and exports your full URL list as CSV or sitemap XML. You import that file directly into Mass Indexer and submit it to Google in one batch. This is the recommended end-to-end workflow for agencies managing SEO across multiple sites.

Google treats it as a recrawl signal, useful when you've updated a page's content or metadata and want Google to re-evaluate it. There is no penalty for resubmitting an already-indexed URL.
