Seven modes

1. Traffic Overview

The fastest mode for lists of up to 10,000 domains:

• monthly visits and three-month history;
• month-over-month and period growth;
• global, country and category ranks;
• bounce rate, pages per visit and visit duration;
• complete acquisition-channel split;
• organic, paid and AI visit estimates;
• top countries and organic keywords;
• AI/LLM referral share, source ranking and chatbot distribution;
• three-month AI-source trends and available top audience prompts.

2. Similar Sites

Find up to 20 competitors and alternatives for each domain, including:

• similarity rank and score;
• estimated monthly visits;
• category and country rank;
• description and preview URL.

3. Complete Profile

Combines traffic and competitors with expanded domain and company intelligence:

• registration date, domain age, expiry, registrar and nameservers;
• DNSSEC and domain status;
• company name, logo and favicon;
• public social profiles;
• detected CMS, e-commerce platform, frameworks, analytics and marketing tools;
• website keyword insights and visible content metrics.

4. Compare Websites

The first input domain becomes the primary website. Every output row receives:

• traffic, growth and AI rank within the batch;
• share of combined traffic;
• traffic gap and relative size versus the primary website;
• acquisition-channel gaps;
• leader, challenger, mid-pack or niche positioning.

A compact cohort report is saved separately as COMPARISON without creating an additional dataset row.

5. Monitor Changes

Use the same monitorKey in recurring or scheduled runs. The Actor remembers the previous baseline and reports:

• traffic and rank changes;
• acquisition-channel shifts;
• added or removed keywords;
• added or removed competitors;
• technology changes in Complete Profile monitoring.

Choose low, medium or high sensitivity. Enable onlyChanges to keep unchanged domains out of the dataset.

6. Market Map

Enter one or more seed websites. The Actor discovers their strongest competitors, enriches the selected domains and returns:

• market-map nodes and seed relationships;
• connection count per website;
• mapped traffic share;
• traffic, growth, rank, category and AI metrics;
• graph edges in the MARKET_MAP output record.

7. Website Discovery

No domain list is required. Discover:

• top websites worldwide or within a country;
• category leaders;
• rising and falling websites;
• new top-list entries and recently dropped websites.

Enable enrichment to add traffic, growth, channels, keywords and AI metrics to every discovered domain.

Outputs

• Dataset — one structured row per returned website. By default, every unique valid input domain receives either data or a clearly marked status row.
• OUTPUT — run statistics and mode-specific summary.
• FAILED_DOMAINS — invalid, unavailable or zero-data domains ready for retry.
• COMPARISON — cohort rankings and leaders.
• MONITOR_SUMMARY — baseline and changed-domain counts.
• MARKET_MAP — graph edges and mapped-market summary.
• DISCOVERY_SUMMARY — discovery settings and result count.

Focused dataset views make Overview, Acquisition & AI, Competitors, Complete Profile, Comparison, Monitoring, Market Map and Discovery easy to inspect in the Apify Console.

Reliability and scale

• Automatic URL normalization and deduplication.
• Stable output order for bulk input reconciliation.
• Explicit success, no_data or failed processing status.
• Field-level coverage flags instead of ambiguous empty values.
• Failed-domain output for partial reruns.
• Lightweight Overview mode for high-volume enrichment.
• Explicit limits for market-map expansion.
• Run summaries include duplicate count, status totals and data-completeness percentage.

Set returnFailureRecords to false if you prefer successful dataset rows only. Retry-ready failures remain available separately in FAILED_DOMAINS.

Availability varies by website. Traffic figures are estimates rather than first-party analytics. Smaller or recently launched domains may have limited data.
