5 SEO Audit Tools for Websites in More Than One Language

For a website in several languages, choose an SEO audit tool that can reach the related language versions, not just the homepage. Then separate two questions: are the pages technically usable, and are their language relationships configured correctly?

A healthy English page doesn't tell you whether its German equivalent redirects somewhere unexpected or points its canonical back to English.

These five tools help with different parts of that review. This is a comparison of official documentation checked on November 14, 2026, not a hands-on benchmark. I'm a co-founder of Screpy, which is included below.

Check the whole language group

Start with an inventory of equivalent pages. For example, these illustrative URLs represent one content group:

Google's localized-page guidance supports hreflang in HTML, HTTP headers or XML sitemaps. Those methods are equivalent from Google's perspective. Check the method your site actually uses.

The language versions should identify themselves and their alternates, with reciprocal links and fully qualified URLs. Don't assume a folder name proves the page contains the right language, or that an annotation proves Google has indexed it.

These roles overlap, but they aren't interchangeable. A status-code report and a reciprocal hreflang check establish different things.

1. Google Search Console

URL Inspection is the free starting point when the question is whether Google has indexed a particular language version. You need access to the property containing that URL.

Inspect representative pages from each locale rather than treating the default language as the entire website. Read the indexed result and Google-selected canonical. A live test answers a different question about current indexability; it doesn't predict Google's canonical choice.

For example, if the German setup page is missing from search, checking its indexed evidence is more useful than changing hreflang simply because a generic audit score dropped.

Search Console is useful evidence in the audit, but this URL-level workflow isn't a replacement for checking the complete set of alternate relationships. Keep the crawler's current observations separate from Google's stored version.

I'd use it alongside a crawler when an important translated page appears to be excluded or consolidated unexpectedly. Neither an accessible URL nor a successful live test guarantees indexing or rankings.

2. Screaming Frog SEO Spider

Screaming Frog's hreflang audit workflow covers annotations in HTML, HTTP headers and XML sitemaps. It is a useful option when you want to investigate the relationships in detail rather than just see an issue total.

The setup matters. Enable crawling and storing hreflang, and include linked XML sitemaps when they contain the annotations. For language versions on different domains, the tutorial explains the additional configuration needed to download and process those external pages fully. Checking an external URL's status alone isn't enough to inspect its return annotations.

The documented hreflang workflow requires a paid licence. The pricing page served during research showed €245 per user per year; it also offers other currencies. The free crawler's 500-URL limit doesn't mean that all advanced audit features are free. Practical paid crawl size still depends on memory and storage.

I'd compare it when your site spans several domains or when you need precise control over what the crawler follows. Record that configuration with the report so the next audit covers the same language group.

3. Sitebulb

Sitebulb's international auditing is worth comparing when your team wants organized hreflang findings and explanations. It checks alternate relationships and HTML language declarations alongside the wider technical audit.

Its International report guide makes an important coverage point: restricting the crawl to /de/ prevents it from validating incoming reciprocal annotations from excluded folders such as /en/ and /es/. Enable the International report and include XML sitemaps as a source if that is where your annotations live.

A reported mismatch is a reason to inspect the implementation. It isn't proof that the translation is wrong or that Google has selected the wrong language in search.

The Desktop plan comparison lists 10,000 URLs per audit for Lite and a default 500,000 for Pro. Pro adds capabilities such as audit comparisons and scheduling. Confirm that the selected tier includes the international analysis you need, rather than choosing solely by URL capacity.

The dynamic page returned no readable subscription amounts during research, so check the current price and billing period directly. I'd compare its guided workflow against the effort of configuring and interpreting a more manual crawl.

4. Ahrefs Site Audit

Ahrefs Site Audit offers a hosted workflow with localization checks alongside indexability, redirects, links and other technical findings.

One useful example is its documented multiple URLs for the same hreflang target issue. Two different URLs declared for the same en target are different from separate en-US and en-GB targets. Review the exact language-region code before merging or deleting annotations.

That distinction can help turn a generic localization warning into a specific template investigation. It doesn't establish whether the pages are useful equivalents or whether their translations preserve the intended meaning.

For verified websites, Ahrefs Free includes 5,000 crawl credits per project per month. Credits are consumed by HTML pages returning 200, rather than every redirect, broken URL or non-HTML resource. Check report access and crawl settings for your account before sizing the audit.

I'd compare it when you want ongoing hosted reports, especially if you already use Ahrefs. A monthly credit allowance isn't the same as an unlimited number of complete audits across every language.

5. Screpy

Screpy Website Audit fits the general technical side of a multilingual review: response codes, redirects, canonicals, metadata, headings and links across the pages reached by a crawl.

For a translated section, those findings can help identify a repeated problem such as missing titles, broken internal destinations or unexpected canonical targets. First check that the important locale URLs actually appear in the crawl inventory.

Coverage depends on links, depth, URL capacity and access. JavaScript rendering is available as a crawl setting, but it doesn't bypass authentication, bot protection or scope limits.

I wouldn't treat this general audit as proof that every reciprocal hreflang relationship is valid. For that specific job, compare the dedicated international workflows above. Likewise, an issue-free crawl doesn't establish translation quality.

The Pro plan lists five projects and 5,000 crawl pages per project, at a regular $192/year, equivalent to $16/month paid upfront. Count all relevant locale URLs against the selected crawl's capacity. Welcome discounts are conditional; check the final total and renewal terms. The seven-day trial becomes paid unless cancelled, and subscriptions renew automatically. AI Visibility is not included in Pro.

With Screpy MCP, an assistant can inspect supported completed-crawl findings and URL details while you investigate. Keep its answer tied to the selected crawl and affected URLs. Connecting the assistant doesn't grant more capacity or automatically repair your locale templates.

I'd compare Screpy when you want a practical technical fix queue alongside the rest of your SEO work, with a separate check for any language relationship the audit hasn't established.

Count locale URLs before choosing a plan

Suppose a site has 2,000 content pages, each published in three languages. That is 6,000 locale URLs before adding other crawlable pages. This is an illustrative sizing calculation, not a measurement of a real site.

A 5,000-page crawl limit could leave part of that inventory outside the audit. A monthly credit allowance may also need to cover repeat crawls after fixes. Check what the vendor counts and how separate domains or projects affect the allowance.

For the first review, choose one important content group and record the following for each language URL:

1. Is it in scope, reachable and serving the intended page?
2. What canonical and indexing directives does it declare?
3. Which alternates does it list, and do the other versions point back?
4. Does the content represent the same intended page for that audience?

Then expand the technical checks across the relevant templates. Keep a human language review in the process; structural validation can't tell you whether a translated instruction, product claim or call to action makes sense.

Choose the tool around the missing evidence. Use Search Console for Google's indexed view, a dedicated international crawler workflow for alternate relationships, and a broader audit workspace for technical patterns and follow-up work. The useful result is a complete enough inventory and a specific fix, not just a better-looking health score.
