What is spbot?
spbot is the web crawler for SEOProfiler and its free tool OpenLinkProfiler. The bot crawls web pages to discover and catalog backlinks, powering the backlink analysis features of both platforms. OpenLinkProfiler provides a free backlink checker service, while SEOProfiler offers comprehensive paid SEO tools. The bot respects robots.txt directives.
