Audit & Technical SEO · Glossary term

Crawler explained without jargon.

The software program that does the crawling. Each search engine has its own crawler (Googlebot for Google, Bingbot for Bing). And SEO tools have their own crawlers — ours runs locally on your machine.

Extended definition

Context and application

Major commercial crawlers (Ahrefs, SEMrush, Moz) run on proprietary servers — they send all your data through their cloud. Difference with a local crawler: your client’s data never leaves the device. For consultants with compliance obligations (medical, legal, financial), this eliminates the need for DPAs with sub-processors. See our article GDPR and cloud SEO tools for full context.
