Why Bulk Domain Authority & Page Authority Matter for Modern SEO

When prospecting for link building, evaluating expired domains, or auditing your competitors' link profiles, checking domains one-by-one is excruciatingly slow. PulseRank solves this bottleneck by providing a high-speed batch evaluation engine that queries authority metrics in parallel chunks with automatic deduplication, caching, and smart error isolation.

01

Input & Cleanse

Paste raw lists of URLs. PulseRank automatically strips tracking parameters, handles punycode, standardizes schemes, and discards duplicates.

02

Parallel Provider Lookup

Queries are batched and executed concurrently against our Redis cache and licensed provider APIs, streaming progress in real-time.

03

Filter, Compare & Export

Slice metrics with interactive range sliders, select up to 4 domains for side-by-side metric charts, and download clean Excel workbooks.

Frequently Asked Questions

Everything you need to know about metrics calculation, credits, and accuracy.

What is Domain Authority (DA) and how is it scored?▼

Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how likely a website is to rank on search engine results pages (SERPs). Domain Authority scores range from one to 100, with higher scores corresponding to a greater ability to rank. PulseRank connects directly to the licensed Moz API or our deterministic high-fidelity provider.

How does the Spam Score metric work?▼

Moz's Spam Score represents the percentage of sites with similar features that have been penalized or banned by Google. A score of 1% to 30% is considered Low Spam Score, 31% to 60% is Medium, and 61% to 100% is High Spam Score. A high score suggests caution when acquiring backlinks.

How many URLs can I check simultaneously?▼

Guest visitors can analyze up to 5 URLs per batch with Cloudflare verification. Free registered members can check up to 10 URLs per batch with 30 free daily credits. Starter and Growth plans can check 50 to 250 URLs per request, and API Pro customers can check up to 1,000 URLs per request.

Can I export my bulk check results?▼

Yes! You can export your filtered results directly to Microsoft Excel (.xlsx), CSV, or copy the formatted table directly to your clipboard for instant spreadsheet paste.

How often is the domain metrics cache refreshed?▼

Our Redis cache stores metric lookups with a 24-hour Time-To-Live (TTL). If a domain has been checked within the last 24 hours, the result returns instantly in under 50ms without consuming additional credits. After 24 hours, fresh live metrics are pulled directly.

How does PulseRank ensure metric accuracy?▼

PulseRank connects strictly to licensed APIs (Moz for DA/PA/Spam Score and Ahrefs for DR/UR) via server-side provider adapters. We never scrape or approximate numbers, ensuring 100% fidelity to official industry standards.
