FAQ

Frequently asked questions

Does the Internal Link Checker require any account registration or subscription fees?
No. Internal Link Checker runs 100% free inside your browser tab without account signups, credit cards, or usage caps.
How does Internal Link Checker protect my input data and privacy?
All processing for Internal Link Checker takes place locally in your web browser memory. Zero input bytes or file streams are transmitted to remote servers.
Can I use Internal Link Checker without an active internet connection?
Yes. Once this page has loaded in your web browser, the client-side JavaScript engine for Internal Link Checker functions fully offline without needing network access.
What is an internal link?
An internal link is a hyperlink that targets another page on the same domain or website structure. They are crucial for distributing SEO page authority and helping users navigate.
What is the difference between follow and nofollow links?
Dofollow links allow search engines to pass link authority (link juice) to the target page. Nofollow links (rel='nofollow') instruct search engines not to associate your page's authority with the destination.
How many links per page is optimal for SEO?
While Google can crawl hundreds of links per page, a general best practice is to keep links under 100 per page to preserve page value distribution and prevent looking spammy.
Are relative paths checked as internal links?
Yes! The crawler detects links starting with '/', './', or absolute paths matching the context domain as internal links, while absolute paths pointing elsewhere are audited as external.
Is my proprietary source code uploaded online?
Absolutely not. All HTML code analysis is performed locally in your browser sandbox using javascript regex. It works completely offline.
Detailed Guide

Understanding Internal Website Link Architecture, PageRank Distribution & Crawl Budget

An Internal Link Audit extracts all hyperlinks from HTML source code to analyze internal vs external link ratios, ensuring search engine bots efficiently crawl core website pages without getting stuck in dead ends.

PageRank Link Equity flows through internal links to establish site hierarchy. Pages with high internal link counts rank higher for target search queries, while orphaned pages with zero internal links fail to get indexed.

Auditing rel="nofollow" attributes on internal links prevents accidental blocking of Googlebot crawl pathways across important navigation silos.
