How to Use Screaming Frog to Improve On-Page SEO
Managing your website’s on-page SEO can often feel like an endless puzzle. Solving one problem reveals two more. But with the right systems, this complexity becomes controllable. This comprehensive guide will teach you how to use Screaming Frog to improve on-page SEO, breaking down a multifaceted process into clear, actionable steps.
Screaming Frog is one of the most respected website crawlers, favored by novices and advanced SEOs alike. It audits your site the way search engines do, providing detailed technical insights and reporting on everything from metadata to broken links. By mastering a few core functions, you can identify, prioritize, and resolve site issues that otherwise go unnoticed—and see a marked improvement in both ranking and user satisfaction.
Let’s dig deeper into why this tool is so effective, how to get started, and how to leverage its full capabilities for optimal on-page results.

What is Screaming Frog and Why Do You Need It?
The Screaming Frog SEO Spider is a robust desktop application built specifically to crawl your website’s URLs in much the same way that Googlebot or Bingbot does. As it navigates each page, it gathers a wealth of information—titles, metadata, headings, images, status codes, response times, and more—and structures it all in a filterable interface.
This tool is invaluable for several reasons:
- Uncover Hidden Issues: Many technical or on-page errors are hard to spot without systematically crawling your site. Screaming Frog acts as a digital x-ray, revealing broken links, duplicate titles, server errors, and even thin content at scale.
- Actionable Prioritization: Once collected, data can be filtered to surface your most pressing problems—such as missing page titles or images without alt text—so you can prioritize workloads efficiently.
- Essential for Technical SEO: New content and even minor site changes can introduce errors. Regular crawls catch these early, helping maintain a strong technical SEO foundation.
- Efficiency: It automates many manual checks, saving hours by surfacing issues with just a few clicks.
Free vs. Paid Versions:
The free edition of Screaming Frog allows you to crawl up to 500 URLs per website, which may be sufficient for small and medium-sized businesses. The paid license removes crawl limits and introduces advanced features like API integrations (Google Analytics, GSC, PSI), JavaScript rendering for modern sites, and crawl scheduling, enabling ongoing automated audits for large organizations.
Feature Comparison | Free Version | Paid Version |
Crawl Limit | 500 URLs | Unlimited |
JavaScript Rendering | Not Available | Available |
API Integrations | Not Available | Available |
Crawl Scheduling | Not Available | Available |

Getting Started: Your First Crawl
The initial crawl sets the baseline for your site’s health. Don’t be intimidated—setting up is fast and intuitive:
- Download & Install: Visit the Screaming Frog website and download the SEO Spider software for Windows, macOS, or Linux.
- Launch and Enter URL: Open the app. In the main dashboard, input your homepage URL (or the starting point for your audit).
- Configure as Needed: The default settings cover most use cases. However, advanced users can configure exclusion rules for unimportant directories, set user agents, or limit crawl speed to avoid server strain.
- Start the Crawl: Press “Start”. The crawler analyzes your website and populates the window with real-time results.
- Watch for Progress: Progress bars indicate completion status. For large sites, pause or resume as needed.
- Crawl Complete: Once all URLs have been processed, results across tabs (internal, external, images, response codes, etc.) are available for in-depth review.
Pro tip:
Before crawling a large, resource-heavy site, adjust the crawler’s speed in Configuration > Speed, and consider crawling during low-traffic hours to minimize server load.
Setting up and running a basic crawl is the first step toward consistent on-page improvement. Save your crawl files for future comparisons—tracking change over time is a vital aspect of professional SEO.
7 Key Checks for On-Page SEO
Once your crawl data is available, use these checks to uncover and fix the site issues most likely to damage your rankings and user engagement.
1. Finding and Fixing Page Title Issues
Why it Matters:
Page titles are critical touchpoints between your content, search engines, and potential visitors. The title appears in browsers, on SERPs, and in external shares, shaping how your site is understood and clicked.
How to Audit:
- Go to the Page Titles tab.
- Use filters to identify pages with:
- Missing: No title tag is present—a missed opportunity for contextual signals.
- Duplicate: More than one page with the same title confuses search engines.
- Too Long (typically over 60 characters): These get truncated in results, hiding information.
- Too Short: May lack sufficient detail or keyword focus.
Action Example:
Suppose you sell custom planners. If multiple pages say, “Custom Planner,” create unique, descriptive titles like, “Weekly Custom Planner – Refillable & Personalized.”
Addressing these issues improves your click-through rates and helps engines better categorize your site’s pages.
2. Optimizing Your Meta Descriptions
Why it Matters:
While meta descriptions don’t directly affect rankings, they work as organic ad copy, heavily influencing click-through from search results.
How to Audit:
- Navigate to the Meta Description tab.
- Find entries that are:
- Missing: No summary provided.
- Duplicate: Several pages share identical text, which can reduce relevance.
- Too Long (over 155 characters): Will be cut off in results.
- Too Short: May fail to excite or inform the user.
Action Example:
If a product page’s meta reads, “Buy planners online,” expand to “Shop personalized weekly planners—customize covers, layouts, and more. Free shipping on all orders.”
Test different descriptions over time to optimize for clicks—the outcome is often measurable with Google Search Console.
3. Auditing Your Heading Tags (H1 and H2)
Why it Matters:
Headings set the structure for both human readers and bots. The H1 serves as the primary topic indicator. Subheadings (H2, H3) help users scan and digest page content, and allow search engines to better parse thematic relevance.
How to Audit:
- Use the H1 tab to check for missing or multiple H1s on a single page.
- Best Practice: Each page needs a single, keyword-relevant H1 aligned with its title.
- Use the H2 tab to ensure subtopics are clearly defined and not missing.
Action Example:
A homepage with no H1 could confuse both engines and users. Add a clear H1, such as “Personalized Planner Solutions for Every Schedule.”
Structured headings also increase accessibility, making content easier to navigate for those using assistive technology.
4. Uncovering Broken Links (404s)
Why it Matters:
Broken links damage user trust and site credibility. They also waste crawl budget and may signal neglect to search engines.
How to Audit:
- Visit the Response Codes tab and filter by “Client Error (4xx).”
- For each 404, use the “Inlinks” tab to see all internal sources linking to the broken page.
Action Example:
If you updated a blog URL but forgot to change links in old articles, site visitors (and crawlers) will hit a dead end. Fix by updating links or applying 301 redirects to guide users to the correct content.
A broken link audit should be done during every crawl—sites evolve, and even minor changes create breakage over time.
5. Checking for Missing Image Alt Text
Why it Matters:
Alt text ensures everyone, including visually impaired users and search engines, understands what an image represents. It may also contribute to image search rankings.
How to Audit:
- Use the Images tab and filter for “Missing Alt Text.”
Action Example:
Replace blank or generic alt attributes. For a product image previously labeled as “image.jpg,” use:
“Alt: Custom leather-bound weekly planner, brown.”
Not only does this help crawlability, but it also supports accessibility compliance (important for many industries).
6. Analyzing Your Internal Linking Structure
Why it Matters:
Internal links distribute authority (“link juice”) and direct users to related content, increasing time-on-site and pageviews. Strategic linking supports topic clusters and improves crawl efficiency.
How to Audit:
- Examine the Internal tab.
- Pay attention to:
- Crawl Depth: Key pages should be reachable within 2–3 clicks from the homepage.
- Inlinks: Important pages with low inlinks might be isolated, making them harder to rank.
Action Example:
An in-depth guide buried five clicks deep may never be found by users or bots. Add internal links from popular blog posts or the homepage to surface this resource.
Pro tip:
Linking contextually (“Learn more about planner customization in our guide”) is more SEO valuable than lists of unrelated links.
7. Identifying Thin or Duplicate Content
Why it Matters:
Quality, unique content is essential for strong rankings. Thin pages (very little content) appear unhelpful, while duplicate content can confuse search engines and split ranking signals.
How to Audit:
- Sort the Internal tab by “Word Count” to spot short pages.
- In the Content tab, filter by “Exact Duplicates.”
Action Example:
If your FAQ section exists on both the main site and product pages with no changes, consolidate by linking to a canonical version. For thin content (e.g., “Contact Us” pages with just an address), consider merging with a related page, or adding a detailed company overview.
Canonical tags, 301 redirects, or rewriting/consolidation often solve these issues.
Advanced Screaming Frog Features
Once you have the essentials under control, leverage Screaming Frog’s advanced features to gain even greater insights, especially if you manage larger sites or need automation.
API Integrations
By connecting your Google Analytics, Google Search Console, and PageSpeed Insights accounts, Screaming Frog pulls in real data about traffic, user engagement, and core web vitals for every crawled page. This reveals, for instance, which pages with SEO errors are also underperforming, helping you prioritize fixes for maximum ROI.
Example:
If certain pages have high impressions but low clicks, combine this with crawl data on poorly written meta titles or slow performance to direct your focus.
Crawling JavaScript Websites
Modern websites often rely on JavaScript (React, Angular, Vue) to display content. Traditional crawlers can miss this content.
Switch to JavaScript Rendering in Screaming Frog’s settings to emulate a browser and capture visible elements.
Example:
A SPA (Single Page Application) might hide product descriptions from the initial crawl. With JavaScript rendering enabled, Screaming Frog uncovers and audits all rendered content, ensuring nothing is overlooked.
Generating XML Sitemaps
Search engines depend on XML sitemaps to find and index critical content quickly. Screaming Frog can automatically generate a sitemap tailored to your actual site structure post-crawl.
How:
After a crawl, go to Sitemaps > Create XML Sitemap. You can customize inclusion based on response codes, meta robots settings, last modified dates, priority, and frequency.
A robust sitemap, built from crawl data, helps ensure all important sections of your site are indexed efficiently.
Remember, a clean sitemap complements a strong topic cluster strategy and makes reporting easier.
