Can I compare multiple competitor URLs side by side?

Yes. You can paste up to 5 URLs to benchmark title tag pixel widths, heading hierarchy depth, word volume, Flesch reading levels, and Core Web Vitals side by side in a synchronized comparison matrix.

How does the N-gram keyword gap matrix calculate missing phrases?

Our engine tokenizes raw text from all audited URLs and extracts 1-grams, 2-grams, and 3-grams. It calculates frequency across all competitor pages and highlights terms that appear repeatedly across top-ranking rivals but are absent or underutilized on your page.

What are the daily audit limits during the Public Beta?

During our Public Beta, AnalyzeSERP is 100% free! You can run batches of up to 5 URLs at a time with a quick 120-second cooldown reset. There are no paywalls or credit card requirements.

Do I need an account or credit card to run competitor audits?

No account or credit card is required to perform audits. You can immediately paste competitor URLs and generate instant audit reports. Creating a free account enables persistent audit logging.

Can I export the competitor audit results into a client-ready brief?

Yes. You can export a comprehensive Markdown content brief (.md) or generate a 3-page unbranded Executive White-Label Vector PDF report customized with your agency name, client URL, and consultant notes.
