Small SEO Tools

Small SEO Tools is a comprehensive collection of free online utilities for search engine optimization analysis, content checking, and web investigation. For OSINT investigators, web analysts, and security researchers, Small SEO Tools provides quick access to a wide range of utilities that help characterize websites, verify content authenticity, and analyze web infrastructure without requiring specialized software.

The platform offers over 100 individual tools covering areas including: plagiarism detection (checking whether web content has been copied from other sources), keyword analysis (identifying what terms a site is optimized for), backlink checking (revealing which other websites link to a target), DNS lookup, IP geolocation, WHOIS queries, page speed analysis, and meta tag inspection. This breadth makes it a useful starting point for website reconnaissance before diving into specialized tools.

For OSINT investigations, the plagiarism checker is particularly relevant: when investigating content farms, disinformation sites, or fraudulent businesses, checking whether their content is copied from legitimate sources reveals low-quality, deceptive, or automatically generated websites. A site whose content is substantially plagiarized from reputable sources suggests a deceptive operation or low-quality content factory.

The domain authority checker and backlink analyzer reveal a website's standing in the broader web ecosystem — how many sites link to it, what those sites are, and how established the domain is. New domains with suspiciously high link counts may be participating in link exchange schemes or SEO manipulation, while legitimate long-standing businesses typically accumulate backlinks organically over time.

The keyword density analyzer reveals what topics a page is most heavily optimized for — useful for understanding a site's primary purpose and target audience. Pages optimized for high-value commercial keywords alongside suspicious content signals may indicate affiliate fraud or SEO poisoning.
