Technical Architecture & Execution Mechanics
Google PageRank Flow & Rel Nofollow Link Topology
Search engines distribute equity across a directed graph $G = (V, E)$. Outbound links without `rel="nofollow"` pass PageRank weight: $PR(u) = \frac{1-d}{N} + d \sum_{v \in B_u} \frac{PR(v)}{L(v)}$. Tagging paid or untrusted links with `rel="sponsored"` or `rel="nofollow"` prevents manipulative algorithmic penalties.
\text{Link Equity Transfer} = \frac{PR(\text{Page})}{\text{Count}(\text{Dofollow Outbound Links})}Technical Limitations & Operational Constraints
- Audits the provided HTML snippet locally; for full-domain crawling, paste sitemaps or individual page source snippets.

Frequently Asked Questions & Answers
What is reverse tabnabbing?
When opening links in `target='_blank'` without `rel='noopener'`, the opened page can access `window.opener` to redirect the parent tab to a phishing site.
What is the difference between nofollow and sponsored?
`rel='sponsored'` is recommended by Google for paid advertising links, while `rel='nofollow'` is used for general untrusted content.
