SEO Spider Crawler & Free Website Auditor.
The crawl depth of a paid desktop crawler, in an interface you can actually navigate. Every technical signal is captured, grouped by issue, and filterable down to the exact set of URLs you need to fix. Built by SEOforVA for our own Virginia campaigns, free for everyone, with no URL cap and no account.
| URL Path | Status | Title | Health |

Every technical signal.
One powerful dashboard.
Unlimited crawling
Crawl a five-page site or a five-hundred-thousand-page one. No URL ceiling, no daily quota, no paywalled depth. Concurrency, crawl depth, and request rate are all configurable per project.
Filtering that does the thinking
This is the part other crawlers get wrong. Stack filters across status code, indexability, depth, word count, response time, and any header or tag, then save the combination as a view you reuse on every audit.
Reports built around problems
Findings arrive grouped by issue and ordered by severity, not dumped into one enormous table. You see that 38 pages share a missing canonical before you see the 4,000 URLs that are fine.
Links and redirects
Every 301, 302, 404, and 410 mapped, including multi-hop chains and loops. Trace exactly which page links to a broken URL so the fix takes minutes instead of an afternoon.
Internal link structure
Your internal linking rendered as a navigable graph. Orphaned pages, dead-end sections, and hubs soaking up more links than they deserve become obvious at a glance.
Structured data validation
Extract and validate structured data on every crawled page, and flag markup that will fail rich-result eligibility. Invalid LocalBusiness schema across a whole template is a common and costly find.
What is an SEO spider, and why should you run one on your website?
An SEO spider is a crawler that visits every page of your website the same way Google does, following every link, reading every title, checking every redirect. Your site might look perfect in a browser while quietly carrying broken links, missing schema, duplicate titles, and slow pages that hold back your rankings. A crawl surfaces all of it in minutes, so you fix problems before Google penalizes them.
Technical issues cost you calls, not just rankings
When a homeowner searches "junk removal Richmond" or "pressure washing Virginia Beach" and your city page returns a 404 or takes five seconds to load, that call goes to a competitor. Most business owners never find out, because the site looks fine when they browse it themselves. A crawl checks every page, every time, and shows you exactly what a customer or a search engine hits.
It sees your site the way Google sees it
SEO Spider reads status codes, titles, meta descriptions, canonical tags, structured data, and internal links across your entire site. That surfaces the problems browsing can never reveal: orphaned pages no link points to, redirect chains leaking authority, duplicate titles across your service pages, and LocalBusiness schema that silently fails validation.
When to run a crawl
Run a full crawl before and after any website change, a redesign, new city landing pages, a platform migration. Then run one monthly as a health check. Prioritize the fixes in order: broken links and 404s first, then missing or duplicate titles and descriptions, then schema errors, then Core Web Vitals. Each fix compounds with the next.
Why it’s free, and what the catch isn’t
We built SEO Spider in-house because we run these audits on every Virginia campaign we manage, and the established tools either cap the free tier at a few hundred URLs or put basics behind an annual licence. There is no upsell inside the app, no account, and no data leaving your machine, the crawl runs locally. If the report surfaces more than you want to fix yourself, fixing it is what our team does every day, and that is the only thing we are selling.
Engineered for specialists.
Smarter than the frog.
Desktop crawlers are powerful and, mostly, punishing to use. We kept the depth and rebuilt the part everyone actually fights with: finding the handful of URLs that matter inside a crawl of thousands.
| Architecture | Legacy | SEO Spider |
|---|---|---|
Free tier crawl limit | Typically capped at ~500 URLs | Unlimited, always |
Cost for full features | Annual licence required | Free, no licence |
Learning curve | Dense grid, steep ramp-up | Issue-led UI, usable on day one |
Report filtering | Single-column filters | Stackable, saveable filter views |
Issue prioritisation | You decide what matters | Grouped and severity-ranked |
Live results while crawling | Mostly post-crawl | Populates as the crawl runs |
Custom extraction (regex / XPath) | Usually paid tier | Included |
Account or licence key | Required | None, download and run |
Before you download
Is SEO Spider really free, or is there a paid tier later?
It is free to download and free to use, with no URL cap, no account, and no trial timer. We built it for our own Virginia client audits and there is no upsell path inside the app. If you would rather hand the fixes to someone, that is our paid service, but the crawler itself stays free.
How is this different from Screaming Frog?
The crawl depth is comparable, the difference is the interface and the reporting. Most desktop crawlers hand you a dense spreadsheet and expect you to know which of the hundreds of columns matter. SEO Spider groups findings by issue, lets you filter and combine those filters without writing formulas, and shows severity so you know what to fix first. It is also free at any crawl size.
Does it run on macOS?
Not yet. Windows is available today and a macOS build is in progress. The crawl engine is already cross-platform, so the remaining work is packaging and signing rather than a rewrite.
Do I need technical skills to use it?
No. Enter a URL and press start, and the app groups what it finds into plain-language issues with a severity order. The deeper controls, custom extraction, crawl configuration, and raw response inspection, are there when you want them but stay out of the way until you do.
Can I export reports for a client or a developer?
Yes. Any filtered view can be exported to CSV or Excel, so you can send a developer exactly the 40 URLs that need a canonical fix rather than a 4,000-row dump they will ignore.
Does crawling my own site affect my rankings?
No. A crawl only requests pages, exactly like any browser or bot, and changes nothing on your site. You can lower the crawl rate in settings if you are on shared hosting and want to be gentle with server load.
How often should I crawl my website?
Run a full crawl before and after any significant change, a redesign, a migration, or a batch of new location pages, then monthly as a health check. Most damaging technical problems arrive with a change rather than appearing on their own.
