Hreflang Tags Testing Tool vs SEO Site Checkup (2026): which should you pick?

Pick Hreflang Tags Testing Tool if

• Fits if you're checking a multilingual site's hreflang setup before launch
• Works for tracking down missing return tag errors from Search Console

Look elsewhere if

• Skip it if your hreflang lives in XML sitemaps or you use a sitemap index, as neither is read
• Not for you if you don't have LinkedIn, the only way to sign in for higher limits and the API
• Tight if your site is large: 30 URLs a test without signing in, and anything past the signed-in limit arranged by email
• Watch out: its pages give different signed-in limits (100 or 250 URLs a test), and the API docs mention a premium tier with no price
• Watch out: the maker describes it as a hobby project run by one person

Pick SEO Site Checkup if

• Fits if you're a freelancer looking after 3 to 15 small sites
• Works for site owners who want each SEO problem explained in plain words

Look elsewhere if

• Too light for big sites, since deep analysis watches just 50, 100 or 300 URLs
• Skip it if AI visibility is why you're here, as it starts on Webmaster at $49
• Watch out: the 7-day trial turns into a paid plan unless you cancel in time
• Not for you if you want it wired into other tools, as no integrations or API are listed

Hreflang Tags Testing Tool

• Hreflang declared inside XML sitemaps is not analyzed; the sitemap is only used to find URLs.
• Signing in works only through a LinkedIn account.
• Its pages give different limits for signed-in users (100 or 250 URLs per test), and higher limits are arranged by email.
• The maker describes it as a hobby project; the API docs mention a premium tier with no published price.

SEO Site Checkup

• Plans cover 3, 5 or 15 sites, and deep analysis watches only 50, 100 or 300 individual URLs.
• AI visibility, AI content analysis, white-label reports and team seats are not on the Basic plan.
• The 7-day trial turns into a paid plan when it ends unless you cancel; cancelling keeps access to the end of the billing period.

Hreflang Tags Testing Tool

List or sitemap crawl

Tests a pasted list of URLs, one per line, or every page in an XML sitemap. Sitemap index files are not supported.

Return tag and cluster checks

Confirms that every page in a language cluster links back to the others and references itself in its own hreflang set.

Code, canonical and x-default checks

Flags invalid ISO language and country codes, duplicates, canonicals pointing to another URL and a missing x-default.

Page health

Checks that every hreflang URL answers with a 200 status rather than a redirect, 404 or 403. Hreflang sent in HTTP headers is read too.

Excel export and history

Results can be exported to an Excel workbook, and signed-in users can see past tests, re-run them and save favorites.

Free REST API

Signed-in users can generate an API key to submit URL lists or sitemaps and fetch results; the free tier allows 50 URLs per test and 10 tests a day.
