I've been using different link indexers for my SEO campaigns, but the proprietary ping protocol in MonkeyIndexer caught my attention, it seems like a game-changer for getting pages indexed in a timely manner. The fact that 99% of submissions get crawled within 5 minutes is incredibly promising, and I'm eager to see how it performs with my own URLs, especially with a daily free link indexer like MonkeyIndexer that can push multiple submissions at once.
