Free tools
Small SEO tools from the IndexBoost team
Free, no account needed. Text tools run entirely in your browser. Tools that take a URL (the Domain Rating lookup, redirect, indexability and schema checks and similar) have our server fetch the page, since browsers cannot, and we do not store it.
