How to track Perplexity source URLs
Perplexity exposes the source URLs it cites alongside every answer — both in the chat UI and in the API response (the `citations` array on the sonar model). The useful question isn't how to capture the URLs, it's what to do with them. The pattern that pays off: log every cited URL across a set of category prompts, group citations by domain, and rank those domains by share of voice. The top five to ten domains in your category are where most of Perplexity's authority is concentrated, and earning presence on them is the single highest-leverage move for AI visibility.
Diagnose the cause
1. Capture every URL, not just the count of mentions
A mention rate tells you whether Perplexity references you; the source list tells you where it's pulling its evidence from. Most AI-visibility tools log the brand mention but discard the citation data — that's the data you actually need. Save the full citation list per prompt run so you can analyse the source mix later, even if today you only care about whether your brand appeared.
2. Group citations by domain to find the authority cluster
Across a set of 25–50 category prompts, the same handful of domains will appear over and over. That's Perplexity's authority cluster for your category — typically a mix of major directories, review platforms (G2, Capterra), trade publications, and a few high-domain-rank blogs. Brands that win in Perplexity tend to have presence on five or more of those cluster domains; brands that lose typically have presence on fewer than three.
3. Track citation share over time, not at a single point
A single snapshot tells you what Perplexity cites today; a time series tells you which sources are gaining and losing weight. Newer publications climbing the cluster are the early signal of where to invest now. Sources falling out of the cluster — usually because they've stopped publishing or because Perplexity has revised its retrieval — tell you where not to invest. Daily logging across a stable prompt set produces this trend with no extra effort.
Fix it
1. Use Perplexity's API citations field for clean data
Perplexity's sonar API returns citations in a structured array on each completion — URL plus title plus snippet. Hit the API on a schedule with your category prompts, store the citations in a database, and you have a clean longitudinal record. This is dramatically more reliable than scraping the web UI, which Perplexity rate-limits and changes the markup of without notice.
2. Build a per-domain leaderboard, not a per-prompt leaderboard
Aggregate citations across all prompts and sort by total citations. This view reveals which domains genuinely shape Perplexity's category answers — and which ones only matter for one or two long-tail prompts. The top of this leaderboard is your PR and content-distribution target list. Linksii produces this view automatically across every prompt run.
3. Cross-reference with what your competitors are cited on
Once you have a per-domain leaderboard, the next move is to overlay it with the citations going to competitors. Domains where competitors are cited and you aren't are your highest-priority gaps. Domains where you and competitors both appear represent table stakes. Domains where you appear and competitors don't are your moats — protect them with continued publishing and freshness.

Linksii's free AI visibility checker runs a curated set of category prompts across ChatGPT, Claude, Gemini, and Perplexity, and returns a baseline mention rate so you can track changes over time.
Frequently asked questions
Does Perplexity always show source URLs?
Almost always for grounded queries. Perplexity is a retrieval-augmented system, so most factual or category responses come with inline citations. The exceptions: pure-conversational queries that don't trigger retrieval, queries the model answers from its own internal knowledge, and Pro Search responses where citations are sometimes consolidated into a single trail rather than per-claim. For brand-tracking purposes you'll see citations on essentially every relevant query.
Can I get Perplexity citations without using the API?
Technically yes — the citations are visible in the chat UI and you could scrape them. In practice, the API is dramatically more reliable: structured data, no rate-limit surprises, no markup changes. If you only need ad-hoc spot checks the UI is fine; for systematic tracking the API is the right path, and Perplexity's pricing for sonar is low enough that it's not a meaningful cost for most brands.
How often do Perplexity citations change?
Constantly. Perplexity retrieves at query time, so the same prompt asked an hour apart can return overlapping but non-identical citations. Trends only emerge over many runs. That's why a single test isn't a reliable signal — you need at least a week of daily runs to separate noise from genuine source movement.
Are Perplexity citations weighted by Google PageRank?
Loosely correlated, not directly weighted. Perplexity uses its own retrieval ranking, which considers domain authority, freshness, query relevance, and content extractability. A high-PageRank page that's hard to extract structured facts from will lose to a lower-PageRank page that's clearly written and well-structured. Don't assume Google rankings translate one-to-one.
