Do you really need to resubmit your disavow file after an HTTPS migration?

Why does Google require resubmitting the disavow file?

During an HTTP to HTTPS migration, you technically create a new property in Search Console. Google treats HTTP and HTTPS versions as distinct entities, even if they point to the same content. The disavow file submitted for the HTTP version does not automatically transfer to the HTTPS version.

Without manual re-import, previously neutralized toxic link signals could become active again on the new secure version. This means that previously disavowed low-quality backlinks could once again affect your link profile, at least temporarily.

What happens if this step is overlooked?

The main risk concerns sites that have experienced negative SEO attacks or those with a history of aggressive link building. If these toxic links become active again, they could theoretically degrade the perceived quality of your backlink profile.

In practice, the impact depends on several factors: the proportion of disavowed links in your total profile, the severity of those toxic links, and how quickly Google crawls your migrated site. A healthy site with few disavowed links will likely not see any noticeable difference.

How does Google manage the transition between the two versions?

301 redirects from HTTP to HTTPS normally transfer the majority of SEO signals, including PageRank and overall authority. However, disavow works differently: it is an explicit instruction given to Google via Search Console, not a signal automatically passed through the redirects.

Google must therefore relearn which links to ignore for the new HTTPS property. The processing time for a disavow file typically ranges from a few days to several weeks, depending on the size of the file and how often your site is crawled.

• Distinct Properties: HTTP and HTTPS are treated as two separate entities in Search Console
• No Automatic Transfer: the disavow file does not migrate via 301 redirects
• Temporary Risk: toxic links may become active during the transition period
• Processing Time: expect several days to a few weeks for Google to process the new file
• Manual Action Required: you need to download and then re-import the file via HTTPS Search Console

Does this recommendation truly reflect real-world observations?

On paper, Google's logic holds up: two distinct properties require two separate files. However, in reality, few SEOs observe measurable downgrades after an HTTPS migration without an immediate disavow re-import. Why? Because well-configured 301 redirects generally do their job effectively for most signals.

The only cases where this negligence poses a problem are sites with a heavy history of negative SEO or extremely polluted link profiles. For a clean site with healthy link building, the temporary absence of the disavow file often goes unnoticed. [To be verified]: Google has never provided quantitative data on the actual impact of this omission.

In what situations does this action become critically important?

If your disavow file contains hundreds or thousands of domains, it indicates that your link profile has suffered significant attacks. In this context, every day without an active disavow on the HTTPS version represents a measurable risk. Google's algorithms may reintegrate these negative signals into their calculations.

Conversely, if you have disavowed 10-20 domains as a precaution without any real threat identified, the urgency is lower. The issue mainly arises for sites that have previously received manual penalties related to link building: there, any reactivation of toxic links could trigger alerts with Google.

What is the acceptable margin of error in this process?

Google generally tolerates a delay of a few weeks between migration and disavow re-import without dramatic consequences. The algorithms do not react instantly to the reactivation of toxic links. You therefore have a reasonable window of maneuver.

However, be cautious: if you wait several months, some of these bad links might be recrawled and re-integrated into the analysis of your profile. It's better to handle this task within two weeks of migration, ideally on the same day if your disavow file is large. Let’s be honest, this operation takes a maximum of 5 minutes.

What should you concretely do during the migration?

The first step is to retrieve your existing disavow file from the HTTP property in Search Console. Go to Links > Disavow Links > Download the disavow list. This .txt file contains all your disavow instructions, domain by domain or URL by URL.

Once downloaded, open the file to ensure its consistency. Take this opportunity to clean up obsolete entries: some domains disavowed years ago may no longer exist or have changed ownership. This is not mandatory, but it’s the perfect time to tidy up.

Next, log into your new HTTPS property in Search Console and submit this file via the same path: Links > Disavow Links > Import. Google will confirm receipt and begin processing the instructions within a few days.

What mistakes should you absolutely avoid in this process?

A common mistake involves altering the format of the file during manipulation. The disavow file follows a strict syntax: each line contains either a full URL or a domain preceded by "domain:". Any incorrectly formatted line will be ignored by Google without an explicit error message.

Another frequent trap is submitting the file too early, before Google has discovered and indexed the HTTPS version. If your HTTPS property does not yet have any data in Search Console, wait a few days for the initial crawl to occur. Otherwise, your disavow instructions will be applied to a ghost site.

Finally, do not delete the HTTP property from Search Console immediately after migration. Keep it for at least 6 months to monitor the redirects and detect any potential configuration errors. Your HTTP disavow file remains active as long as the property exists, providing temporary double protection.

How to verify that the operation worked properly?

Unfortunately, Search Console does not provide a detailed visual confirmation after importing a disavow file. You will simply see the date of the last import and the number of affected URLs or domains. To check the actual effect, you need to observe indirectly.

Monitor your backlink profile in Search Console over the following weeks. If you had disavowed spammy domains visible in your inbound links, they should gradually disappear from the statistics or be marked as ignored. This serves as an indirect indicator that Google is applying your instructions.

• Download the disavow file from the HTTP property before migration
• Clean up obsolete entries and check the .txt format of the file
• Create and verify the HTTPS property in Search Console
• Wait for Google to crawl and index a few HTTPS pages
• Import the disavow file into the HTTPS property via Links > Disavow
• Keep the HTTP property active for at least 6 months for monitoring
• Check the import date and number of entries in HTTPS Search Console
