Use Case

SEO Audit & Performance Tracking

Capture screenshots for SEO audits and track visual changes over time. Document SERP rankings and competitor positions.

Overview

SEO is increasingly visual. Core Web Vitals, layout shifts, and above-the-fold content all impact rankings. Screenshots help SEO professionals document issues, track progress, and report to clients.

Use Screenshotly to capture SERP pages for ranking documentation, competitor sites for comparison, and client pages for before/after audits. Mobile screenshots are especially valuable for mobile-first indexing analysis.

Agency SEO teams use screenshot automation to scale their auditing process, create visual reports for clients, and maintain historical records of all SEO changes. Combined with performance metrics, screenshots provide the complete picture.

Frequently Asked Questions

How do I document SERP rankings with screenshots?

Capture Google search results pages for your target keywords using the geolocation parameter to specify the country. Store screenshots with the keyword, date, and location for a historical ranking record.

Can I capture mobile vs desktop versions for mobile-first indexing audits?

Yes. Make two API calls per URL — one with device: 'mobile' (375px) and one with device: 'desktop' (1920px). Compare the outputs to identify content, layout, or CTA differences that may affect mobile-first indexing.

How do I create before/after comparisons for client reports?

Capture the client's pages before making changes, implement fixes, then capture again. Use image diff tools or place screenshots side-by-side in your report to visually demonstrate the improvements.

What's the best way to scale SEO audits across many client sites?

Build a queue of URLs per client, process them in batches via the API, and store results organized by client, URL, and date. Automate weekly captures for ongoing monitoring and generate visual reports from the stored screenshots.
