Why you need a subdomain finder

Keeping tabs on subdomains is essential for any site optimization. Search engines consider each subdomain a different site, so you need to optimize each separately to boost overall traffic and improve website performance. A subdomain scanner also helps find duplicate content, which can damage rankings of both the main domain and subdomain. It also helps identify poor-quality backlinks to subdomains that can diminish your SEO efforts.
