Spotibo

Spotibo is an on-page and technical SEO checker that crawls an entire website instead of a single page. It handles JavaScript the way Google does and sorts problems by importance, with urgent warnings for serious threats and no vague overall score. Checks cover title tags and meta descriptions measured in pixels, heading structure, internal links, images with missing or irrelevant alt text, duplicate content, error pages, redirect chains and indexation problems. It also looks at Core Web Vitals, canonical and URL variations, international settings and robots.txt, and it sends alerts when an error appears. Extra utilities include a robots.txt tester and monitor, a SERP preview tool and a meta description checker. A free account crawls a limited number of pages at no charge.
