For most SEO practitioners, the process of crawling a website kicks off with the usual drill. You give a domain, the crawler locates its pages, and you review the technical data.
Screaming Frog has been the go-to tool for this sort of work for years. But it’s not the only option on the table today. Depending on the type of SEO project, the crawling methods will vary, whether you are auditing a live website, checking a migration, reviewing a staging environment or working with a large URL database.
This resulted in the creation of a wider range of SEO crawling tools, each with its own particular way of analyzing websites.
SEO Crawling Is More than Finding Broken Links
A technical crawler offers much more than a list of broken URLs. Depending on the tool, an audit can show:
- Missing or duplicate titles and meta descriptions
- Redirect loops
- Canonical problems
- Problems of Indexability
- Chances for internal linking
- Status Code Error
- Image problems
- Structured data issues
- Duplicate or very similar URLs
- Sitemap inconsistencies
It's the fact that you can gather this data at scale that has value. Rather than manually checking hundreds or thousands of pages, an SEO professional can see patterns and direct attention to the pages that need action.
Different Projects Need Different Crawling Methods
One reason to look at alternatives is that not all audits follow the same process. Although a full site crawl is the logical choice for a technical audit, a migration project might have a specific list of old URLs to work with. There may not even be a public pre-launch website. This is where different crawling modes come in handy.
Complete Website Crawl
The traditional approach is to initialize a domain and have the crawler find pages through internal links. This is useful for general technical audits and large scale website audits.
Web Crawling With Lists
For list based crawling the SEO team feeds the URLs directly. This can be especially helpful for:
- Audits of Migration
- Testing redirection
- Site map review
- Selected page groups
- Large URL inventories
Instead of crawling everything, you can crawl just the URLs relevant to the project.
Crawling Offline
Offline crawling extends the concept even further so that a web site can be analyzed before it is available publicly. This may be useful during development when the website files are stored locally. KWT Spider has an Offline Mode that allows you to analyze local website folders and find issues with elements such as HTML, CSS, JavaScript and images. This gives SEO teams working with developers a way to check technical issues before deployment.
Dealing with Big Crawls
The scale of a website can be a great factor in how usable a crawler is. A small business website may have a few hundred pages. Publishers, ecommerce sites and enterprise sites that are large can have tens or hundreds of thousands of URLs. Handling of crawl data is a concern at this level. KWT Spider has a SQLite Database Mode. Instead of storing the crawl attributes only in the system memory, it stores them in a database on your local drive. This feature is intended for large crawl jobs such as sites with 50,000+ pages. Of course, actual performance depends on your computer, website architecture, response times, JavaScript and crawl configuration. The key is whether the crawler's data-handling approach is suitable for the size of the projects you typically work with.
Looking Beyond the URL List
Another difference between SEO tools is the way they present crawl information. A crawler can generate thousands of rows of data, but without organization, raw data is useless. KWT Spider provides 29 diagnostics views on various aspects of a crawl. These help users navigate through technical information, content data, links, images, structured data and other website signals. Such an organization can help to investigate a large crawl.
For example, rather than having to manually sift through one giant dataset, an SEO pro can “drill down” from a general crawl to a specific area, such as status codes, internal links or metadata or structured data.
GEO and EEAT Assessment
Some of the newer crawlers are adding analysis beyond the standard technical checks. KWT Spider also offers GEO and EEAT readiness analysis that checks for signals such as authorship, entity information, definition clarity, structured data, and trust-related information. The purpose is to give extra diagnostic information, not to forecast if a page will be in an AI-generated answer. That’s an important distinction. Crawlers cannot guaranty AI search visibility and these checks should be considered as complementary to, and not a replacement for, core technical SEO.
Exporting and Working With Crawl Data
SEO audits rarely stop inside of the crawler. Often, teams need to share findings with clients, developers, content teams or management.
So export choices are important. KWT Spider supports formats like CSV, Excel and HTML. It also generates sitemap and llms.txt based on crawl data. These options can be helpful when you need to move crawl findings into spreadsheets, reports, development tickets or other SEO workflows.
Desktop Crawlers Still Have Their Practical Benefits
Cloud-based SEO platforms can be useful for collaboration and centralized reporting, but desktop crawlers have their place in an SEO toolkit as well.
A locally installed crawler is particularly useful when you want to:
- Assistance with site staging
- Check website files locally
- Store crawl data on your box
- Perform targeted URL audits
- Local processing of large datasets
- Conduct technical checks during development
KWT Spider is a desktop application that runs on Windows, macOS and Linux.
KWT Spider As One Alternative to Check Out
KWT Spider is more than a tool to crawl a homepage and follow links. Its workflow is a combination of several approaches:
- Spider mode for normal website crawling.
- List Mode For pre-defined collections of URLs.
- Offline mode for local website files
- SQLite Mode for large crawl datasets
- Additional checks on content and entities using GEO and EEAT analysis.
- The software also provides 29 diagnostic views and supports exports to CSV, Excel and HTML.
This combination makes it particularly relevant for SEO professionals whose projects go beyond simple site-wide crawls.
Factors to Consider When Choosing a Crawler
The right crawler depends on what kind of work you do. Questions to ask before selecting a tool include:
What do you normally crawl?
Live websites, URL lists, staging environments, or local files?How large are your projects?
A crawler that works well for a 500-page website may require a different workflow for a 100,000-page site.How do you use crawl data?
Do you need simple exports, detailed reports, spreadsheets, or developer-ready informationDo you work before launch?
If so, offline or staging-site crawling could be particularly useful.Do you need more than technical checks?
Additional analysis around structured data, entities, authorship, or GEO may be relevant depending on the project.What operating systems does your team use?
Cross-platform support can simplify workflows when teams work across Windows, macOS, and Linux.
Beyond One “Standard” SEO Crawler
There is no “one size fits all” crawling workflow for all SEO projects. Technical audits, migrations, pre-launch reviews and large enterprise crawls can have entirely different requirements. That’s why it’s beneficial to go outside the most familiar SEO crawler and compare tools based on how they fit your real workflow. Screaming Frog is still a solid option, but tools like KWT Spider show that there are different ways to approach SEO crawling. For SEO pros in need of a more comprehensive desktop auditing workflow, KWT Spider offers multiple crawling modes, offline website analysis, database-backed crawling, diagnostic views, and GEO/EEAT checks. The only way to tell which crawler is best is to try it on the websites and problems you actually work with.¬
