If you need to see who links to your site, compare competitor backlinks, or check whether important links are still live, SEO SpyGlass is a practical fit. It is downloadable desktop software rather than a monthly cloud subscription, with a free license for up to 1,100 backlinks per site.
The main tradeoff is that the free edition limits backlink volume and does not include exports or HTML/PDF reports. A site owner may find Professional sufficient, while a freelancer or agency that needs client reports, exports, and larger comparisons will usually need Enterprise.
Key takeaways
- Use the free license first if 1,100 backlinks per site is enough.
- Professional costs $129 per year and suits in-house site work.
- Enterprise costs $259 per year and adds client reports, exports, and larger comparisons.
- Verify questionable links on the live page because crawler data can be incomplete or out of date.
- Check the renewal amount in your payment account before purchase.
What SEO SpyGlass is for
To understand how a site earns authority, start by entering your own URL or a competitor's. SEO SpyGlass can analyze a whole domain, its subdomains, or one exact page, so you can choose between a broad profile and a focused check.
The backlink profile groups links by linking domain, anchor text, linked page, country, IP, and link type. It shows whether a link is live, dofollow, nofollow, embedded, missing, or on a page returning an error. That answers the everyday questions of who links to you and which pages attract the most references.
Competitor comparison is another use. You can create projects for competing sites and compare their linking domains, anchors, and linked pages. The free edition compares two sites, Professional compares six, and Enterprise compares eleven.
It also shows link gains and losses over a date range within the previous year, which helps you spot whether a competitor recently gained links or your own profile lost some.
The software is part of SEO PowerSuite, alongside Rank Tracker, WebSite Auditor, and LinkAssistant. It is a backlink auditing tool, not a host, domain registrar, website builder, or link-generation service. If you are choosing hosting separately, compare options in Best Web Hosting: Which Host Fits Which Site, With Renewal Prices.
How its backlink data is collected and verified
If a backlink report will drive outreach, removal, or a disavow file, you need to know how much to trust it. SEO SpyGlass uses SEO PowerSuite's Link Explorer as its main index, built from the vendor's own crawler.
SEO PowerSuite describes Link Explorer as holding more than 2.7 trillion backlinks and crawling 7.1 billion web pages daily, with a full crawl cycle of about three months. A newer vendor backlink-checker page states 3.6 trillion external backlinks, 264 million domains, 7.1 billion pages crawled daily, and a full database update every four weeks. These are vendor claims about index size and refresh speed. They do not show that every important link is current.
A project can combine several data sources: the vendor index, Google Search Console, Google Analytics, imported CSV data, manually added URLs, and real-time checks of backlink pages. That makes a project more useful, but where a result came from still matters.
A crawler may list a link that has since been removed, or miss one it has not yet reached. SEO SpyGlass offers real-time backlink-page verification to narrow that gap. For links that affect a business decision, open the live page and confirm the page, anchor, rel attribute, and status.
The license agreement also supplies the software as is, with no guarantee that it will be uninterrupted, fast, secure, error-free, or compatible with every device. It is installed software, not a live monitoring service.
What the free version shows and saves
To learn whether SEO SpyGlass fits before paying, start with the free license. It stays available on an ongoing basis and allows up to 1,100 backlinks per site.
The free edition includes backlink analysis, comparison of two sites, a disavow-file generator, project saving according to the current pricing page, scheduled tasks, clipboard copying, and printing. The separate product-order page adds that free users can check unlimited websites and keep backlink history.
The limit counts backlinks per site, not the websites you can enter. That makes the free license useful for a small site, a focused competitor check, or a first look at one page. It may be too narrow if a large domain has more than 1,100 links worth inspecting.
Free export and HTML/PDF report creation are marked unavailable on the standalone order page. You can copy information to the clipboard and print, but that is not the same as a reusable CSV, SQL, or client-ready report.
Try the free license against your own site and one competitor. If the visible backlink set is enough for your decision and you do not need exports, the paid editions may not add enough to justify the cost.
To see the limits side by side, read SEO PowerSuite Free vs Paid: What the Free Version Can Do.
Professional vs Enterprise: limits, exports and client reports
The choice between paid editions depends less on finding backlinks and more on how you need to save, compare, export, and present the work. Both paid editions list unlimited backlinks and unlimited project saving.
Professional compares six sites and is aimed at in-house use. It suits a business owner or marketing team that needs larger projects than the free limit allows but does not deliver work to clients. Its printing carries watermarks, which matters if you share printed reports outside your team.
Enterprise compares eleven sites and adds what client work needs: disavow editing, saving and emailing reports, scheduled delivery, and CSV, SQL, and HTML exports. A freelancer handling several client domains will generally need it if the work must leave the software as a clean report or data file.
One project file can hold up to 250,000 backlinks. If more are identified, the extra backlinks appear separately in the workspace, and paid editions can export full backlink lists by source to CSV.
That makes Enterprise the clearer fit for agencies, consultants, and freelancers who need repeatable reporting. Professional is the better value when you manage your own sites and can work inside the application or accept watermarked print output.
A one-user license is for one user and internal business purposes. Sharing, reselling, sublicensing, or hosting the software for third parties is prohibited unless the agreement expressly allows it, so a client reporting workflow should use the edition that documents those features.
What SEO SpyGlass costs and what renews
To decide whether the annual license is cheaper for your work, treat the listed price as the amount due today and keep the renewal rule beside it. The standalone pricing page lists these annual terms, checked November 9, 2026.
Professional is the practical paid choice for in-house work when the free 1,100-backlink limit is too small. Enterprise costs more because it adds client reporting, exports, delivery, and the larger eleven-site comparison.
Paid licenses are paid 100% in advance and renew automatically for another year unless canceled. Renewal uses the price listed on the website at that time, so $129 and $259 are not a promise of future renewal amounts. Confirm the renewal amount in the payment account before you buy.
Payment runs through 2Checkout. Cancellation can be completed through the 2Checkout account or through support, though the refund policy says it must be completed through the 2Checkout account for security. Refunds are excluded for partial use or unused time, so try the free version before you buy a license.
Read the current refund policy and confirm the cancellation terms before paying. To buy from the vendor, see SEO PowerSuite's current plans.

Desktop software, online checker and cloud projects
If you prefer working in a browser, SEO SpyGlass gives you a narrower choice than a cloud-first backlink platform. The main application is downloadable desktop software for Windows, macOS, and Linux.
SEO PowerSuite also offers an online free backlink checker, a browser-based way to inspect a selection of backlink data without installing anything. The desktop free version analyzes up to 1,100 entries, while the online checker shows a selection of backlinks.
SEO PowerSuite Cloud is separate from the online checker. It stores projects and reports for licensed users and synchronizes selected settings, but it does not replace the complete SEO SpyGlass application in a browser.
The products are desktop software, an online backlink checker, and cloud project storage; there is no Chrome, Firefox, or Edge extension. Choose the desktop software for full projects and the online checker for a quick browser-based look.
Penalty risk, disavow files and the limits of the metrics
If a link looks suspicious, SEO SpyGlass can help you organize the evidence, but it cannot tell you that Google has issued a penalty. Its Penalty Risk metric is an SEO PowerSuite calculation based on factors such as linking-domain age, incoming and outgoing links, and page and domain InLink Rank.
Treat Penalty Risk as a screening signal. InLink Rank and Link Value are also vendor calculations, not Google ranking scores. A high value does not prove a link helps rankings, and a high Penalty Risk does not prove a manual or algorithmic penalty.
The software can generate a disavow file and maintain a disavow list. A disavow file is an instruction file you submit through the appropriate Google process. It does not guarantee that Google will remove a ranking effect, and it does not remove the link from the other website.
A sensible workflow is to open the live backlink page, confirm the link exists, check its placement and rel attribute, identify the linking site, and only then decide whether action is needed. Never remove or disavow a link on a vendor metric alone.
The software does not guarantee complete or perfectly current backlink coverage, rankings, traffic, or link removal. SEO SpyGlass is not a hosting product: storage, bandwidth, email, uptime guarantees, data centers, domain registration, migrations and backups come from your web host.
SEO SpyGlass compared with a cloud backlink tool
The main difference between SEO SpyGlass and Ahrefs is the payment model and how each organizes access. SEO SpyGlass is downloadable annual software. Ahrefs is a cloud subscription with monthly pricing, project allowances, historical-data limits, crawl credits, and export limits.
Ahrefs' US pricing page lists Lite at $129 a month, with five projects, six months of historical data, 750 tracked keywords, 100,000 crawl credits, and 500,000 export rows a month. It also lists a $29-a-month Starter plan. Annual billing is available at a discount, so check the annual Lite quote in your Ahrefs account before choosing it. Prices checked November 9, 2026.
SEO SpyGlass Professional costs $129 for one year upfront, the same number as one month of Ahrefs Lite, but the products do different jobs and carry different limits. SEO SpyGlass may suit a site owner who wants annual desktop software and no monthly subscription. Ahrefs may suit someone who wants a browser-based service with broader recurring access and cloud-managed limits. Renewal is the other check: SpyGlass renews annually at the price shown when renewal occurs, so confirm that amount in your payment account.
Price is not the only question. Decide whether you need saved desktop projects, local workflows, client reports, competitor comparisons, frequent cloud access, or other SEO functions. For a direct cost and data comparison, read Ahrefs vs SEO PowerSuite: Cost, Data and Which Fits You.
