Most migrations don't lose traffic in one big mistake. They lose it in a few hundred old URLs that redirect to the wrong page, or to nowhere.
Migration plugins move files and databases. They don't check that every old URL lands on the right new one. That's the job of the tools on this shortlist.
We read the pricing and help pages of 9 tools on 15 November 2026. We grouped them by job: crawl, map, test redirects and monitor.
We didn't test any tool; prices and limits are what each vendor publishes.
Small site, tight budget? Search Console (free), Screaming Frog ($279 a year) and httpstatus.io (free, 100 URLs per batch) cover crawl, redirect tests and launch checks.
Want before and after audits side by side? Sitebulb Pro lists audit comparisons for $42 a month ($425 billed yearly).
Need rank and audit monitoring after launch in one login? SE Ranking Core, Ahrefs Lite and Semrush SEO cost $1,238.40 to $1,407.96 a year. seotools.pro Pro is $492.
Large site where Googlebot's behavior matters? JetOctopus Growth adds log analysis for $349 a month billed yearly ($4,188 a year).
- Buy for four jobs: URL inventory and mapping, redirect testing, launch checks and post-launch monitoring.
- One year of the plan used here runs from $279 (Screaming Frog) to $4,188 (JetOctopus Growth). Search Console and httpstatus.io are free.
- Budget time for the redirect map itself. You build it in a sheet from crawl and Search Console exports.
- Google says to keep redirects "generally at least 1 year". The Change of Address tool forwards signals for 180 days.
- CMS migration plugins move the site. They don't test redirects or track rankings.

*USD, before tax, vendor pages checked 15 November 2026. "One year" uses yearly billing where listed. 10 rows: 9 tools plus seotools.pro, our own product.
Suites and seotools.pro show the first plan with both site audit and rank tracking. Sitebulb shows Pro, the first plan that lists audit comparisons.
What to look for
In our view, a migration toolkit has to cover four jobs. Check each tool against them.
- Inventory and mapping: can it list every old URL that matters, from a crawl, sitemaps, Search Console and logs?
- Redirect testing: can it test a list of old URLs and show status codes, chains and final URLs?
- Launch checks: can it crawl staging and live, then compare titles, canonicals, noindex and links?
- Monitoring: can it track rankings, indexing and new errors for weeks after launch?
The map comes first. Google puts it plainly:
"It's important to map your old site's URLs to the URLs for the new site."
Google Search Central, Site moves with URL changes (last updated 20 August 2026)The same page says to test redirects with the URL Inspection Tool for single URLs, "or command line tools or scripts to test large numbers of URLs".
Then plan for the wait. Google says a small to medium site "can take a few weeks for most pages to move, and larger sites take longer."
What about CMS migration plugins?
Many results for this search are WordPress plugins like Duplicator, Migrate Guru or All-in-One WP Migration. They copy a site to a new host or server.
That's a different job. If your URLs don't change, you may only need one. If URLs change, you still need the tools below.
How we compared
- In: tools that cover at least one migration job above, with a public USD price, a free tier or public plan limits.
- Out: CMS and hosting migration plugins (a different job), Lumar (quote form only) and Oncrawl (pricing page returned 404 on 15 November 2026).
- Prices, limits and features come from each vendor's pricing or help pages, read on 15 November 2026. We rendered JavaScript pages in a browser.
- "One year" is the cheapest way to pay for 12 months of the plan used. We didn't test any tool. "Choose another option if" is buyer fit, not a score.
- Disclosure: seotools.pro publishes this article and is our product. We have no commercial relationship with the other vendors listed.
Planning the move itself? The free Website Migration SEO Checklist and Redirect Map has 9 variants, from benchmark to post-launch monitoring.
The 9 tools
Two are free, two are desktop crawlers, three are suites, one is a cloud crawler with logs and one is an always-on monitor.
1. Google Search Console: free
Search Console is where the move is announced, tested and watched. You need owner access to both the old and new properties.
- Change of Address: for moves between domains or subdomains. Not for HTTP to HTTPS, www to non-www or path changes on one domain.
- 180 days: the tool forwards signals for 180 days. Its help page says to keep redirects at least that long.
- Testing: URL Inspection checks single URLs. Filter the Page indexing report by sitemap to see how many submitted URLs are indexed.
"Keep the redirects for as long as possible, generally at least 1 year."
Google Search Central, Site moves with URL changes (last updated 20 August 2026)Choose it if you're moving any site. It's step one, and it's free.
Choose another option if you need to test thousands of URLs at once. URL Inspection works one URL at a time.
2. Screaming Frog SEO Spider: free, then $279 a year
The SEO Spider is free up to 500 URLs. A licence costs $279 a year on its US-dollar page.
- List mode: its migration guide says to upload old URLs, switch to list mode and enable "Always Follow Redirects".
- Redirect chains report: shows each old URL, its final URL, hop count, loops and temporary redirects.
- Crawl comparison and URL mapping: compares staging with live, even when hostnames or paths differ. It needs database storage mode.
That parallel crawl matters. Aleyda Solis writes in her migration validation guide:
"It’s critical to do a parallel crawl of the old pages"
Aleyda Solis, 7 Handy SEO Tools Functionalities that facilitate a Fast Web Migrations & Redesigns validation (undated, checked 15 November 2026)Choose it if you want a low-cost licence to crawl old URLs, staging and live, and don't mind a desktop app.
Choose another option if you need rank tracking after launch. It's a crawler only.
3. Sitebulb: Pro from $42 a month
Pro costs $42 a month, or $425 billed yearly, for 500,000 URLs per audit. It's the first plan that lists audit comparisons.
- Pro adds: audit comparisons, scheduled audits, 300+ hints and custom PDF reports.
- Lite: $18 a month ($180 billed yearly), 10,000 URLs per audit, no comparisons listed.
- All plans: JavaScript crawling and GA, GSC and Sheets integration.
Choose it if you want before and after audits with visual reports you can hand to developers.
Choose another option if you need to crawl a large site 24/7 from the cloud. Sitebulb Cloud starts from $125 a month.
4. httpstatus.io: free
A free web tool for bulk status code and redirect checks. Its help page says it "has been free, and always will be."
- Batch size: 100 URLs at a time, with redirect chains, headers and round-trip times.
- Depth: up to ten redirects per URL. Exports go to CSV, XLS or Google Sheets.
- API: for larger checks, with a free tier and paid plans. Prices are in euros, so we left them out.
Choose it if you need a quick launch-day check of your top old URLs without a crawler.
Choose another option if your list runs to thousands of URLs. Its own help page points you to a crawler for that.
5. Semrush: $139 a month
The SEO plan costs $139 a month, or $117.33 billed yearly ($1,407.96 a year).
- SEO plan: 5 websites to monitor, 500 keywords tracked daily, Position Tracking and Site Audit.
- Not listed: Site Audit page limits aren't on the pricing page.
- Free: 10 reports a day with 1 demo project.
Choose it if you want to benchmark rankings before launch and track them daily after, next to Site Audit.
Choose another option if you mostly need a deep crawl of old URLs. A crawler costs less.
6. Ahrefs: $129 a month
Lite costs $129 a month, or $1,290 billed yearly. Prices exclude tax.
- Lite includes: Site Audit, always-on audit, Rank Tracker with 750 keywords updated weekly, and 100,000 crawl credits.
- Backlinks: Site Explorer shows which old URLs have links, so you can map those first.
- Free: Ahrefs Free gives website owners limited access to Site Explorer and Site Audit.
Choose it if backlinks to old URLs are a big part of what you need to protect.
Choose another option if you need more than 750 tracked keywords. Standard lists 2,000 at $249 a month.
7. SE Ranking: $129 a month
Core costs $129 a month, or $103.20 a month billed yearly ($1,238.40 a year).
- Limits: 10 projects, 2,000 keywords tracked daily, 250,000 audited pages a month.
- Change alerts: page changes monitoring is listed on Growth, $279 a month ($223.20 billed yearly).
- Trial: 14 days, no credit card.
Choose it if you want the cheaper of the two suites here with daily rank tracking and audits.
Choose another option if you need page change alerts on the entry plan. Core doesn't list them.
8. JetOctopus: Growth from $349 a month
Growth costs $459 a month billed quarterly, or $349 a month billed yearly ($4,188 a year). It's the priciest plan in our chart.
- Growth: 500K crawled URLs and 2M log lines a month, 3 GSC and 3 GA4 properties.
- Migration use: crawl-to-crawl comparison, plus logs that show whether Googlebot hits old or new URLs.
- Trial: access opens after a demo.
Choose it if you run a large site and want crawl, logs and Search Console data in one cloud tool.
Choose another option if your site has a few thousand pages. A desktop crawler covers it for far less.
9. Conductor Monitoring: price on request
This is the former ContentKing; its old domain now redirects to Conductor. Pricing is quote-based.
- Essentials: 100,000 pages monitored and 3 tracked websites. Growth lists 500,000 pages monitored 24/7.
- Migration use: 24/7 alerts on technical changes and a changelog with up to 60 months of history.
- Trial: "Try Conductor free for 3 weeks".
Choose it if you're an enterprise team that wants alerts during and after launch, not scheduled crawls.
Choose another option if you need a public price before a sales call.
Where seotools.pro fits
We don't offer a desktop crawler, log analysis or bulk redirect lists. Our tools cover launch checks and monitoring.
- Audit before and after: the Website Audit checks status codes, redirect chains and indexing. It scans 20 pages without an account and 500 per audit with a free account.
- Track fixes: paid plans list new and fixed issues between crawls, weekly re-crawls on Lite and daily on Pro.
- Trace one redirect: the free Redirect Checker follows up to 20 hops for one URL per run, 2 free checks a day. Use it to debug, not to test a list.
- Watch rankings: the free Rank Tracker check reads Google's top 10 live. Ongoing tracking starts on Pro.
- Check speed: the free Site Speed Test reads LCP, INP and CLS before and after a release.
Paid plans: Lite $24 a month ($20/mo billed yearly), Pro $49 ($41), Business $99 ($83). Keyword allowances (20,000, 100,000 and 400,000) count keyword lines.
Rank Tracker starts on Pro, so Pro ($492 a year billed yearly) is the plan in our chart. Lite ($240) covers audits with weekly re-crawls. See pricing.

FAQ
What is the best free website migration tool?
Google Search Console for the move itself, plus httpstatus.io for 100-URL redirect batches. Screaming Frog crawls up to 500 URLs free.
How long should I keep 301 redirects after a migration?
Google's site move guide says "generally at least 1 year". The Change of Address help page says at least 180 days, longer if Google still sends traffic.
Do I need the Change of Address tool for an HTTPS move?
No. Google says it's only for moves between domains or subdomains, not HTTP to HTTPS, www changes or path changes.
Will a WordPress migration plugin protect my rankings?
Only if URLs stay the same. Plugins copy the site. If URLs change, you still need a redirect map, a crawl and monitoring.
How long does a migration take to settle?
Google says small to medium sites take a few weeks for most pages to move, and larger sites longer. Rankings can fluctuate meanwhile.
