You request re-indexing on Baidu after fixing hacked content by cleaning your server files and using the site security tools within the Baidu Search Resource Platform. When a site suffers a security breach, the crawler often flags pages as dangerous or irrelevant, which impacts your search presence. Once you remove malicious scripts and restore clean backups, you must signal to the search engine that the site is safe to crawl and index again.
A hacked site poses a significant threat to your search performance, as Baidu prioritizes user safety above all else. If your site was distributing malware or displaying unsolicited advertisements, the platform may have restricted your visibility or removed your pages from the index entirely. Recovery requires a disciplined approach, moving from complete technical sanitization to formal reporting of your site status to the platform.
What is the first step in cleaning a hacked site?
Before asking for a re-crawl, verify that your server environment is completely free of unauthorized code. Attackers often leave backdoors that re-inject malicious content even after you delete visible files. You should check for suspicious files in your root directory and examine your database for injected scripts that might trigger redirects or display harmful content to visitors.
A common mistake is simply restoring a backup without patching the original vulnerability. If the entry point remains open, the site will be re-infected within hours. Ensure that all plugins, themes, and server-side software are updated to their latest stable versions. Reviewing your server logs can help identify the specific timestamps and IP addresses associated with the breach, providing the data needed to secure your infrastructure against future intrusions.
- Change all administrative and database passwords immediately to block unauthorized access.
- Scan your entire server file system to identify and remove injected scripts or hidden backdoors.
- Remove all unauthorized redirects, hidden text blocks, or malicious link injections.
- Verify your robots.txt file to ensure it has not been modified to block the spider or redirect crawlers elsewhere.
How do you communicate the fix to the Baidu platform?
Once the site is clean, use the Baidu Search Resource Platform to report the status. The platform provides specific tools to check if your pages are flagged. If the site has been marked as compromised, look for the security feedback section where you can submit a request for re-verification. This notifies the team that you have addressed the security vulnerabilities.
The submission process is not an instant fix, but it serves as the official record of your recovery efforts. Ensure that you have cleared any browser-side warnings before submitting. If your site still triggers security alerts in a standard browser, the platform will deny the re-indexing request. A clean, stable site is the baseline requirement for any successful communication with the search engine.
Security recovery is not just about deleting files; it is about proving to the system that the site architecture is stable and no longer serves harmful content. We always prioritize a clean server environment before triggering any platform signals.

How does crawl frequency affect your recovery?
Crawl frequency determines how quickly your updates are processed by the engine. If your site was unresponsive or full of errors during the hack, the crawler might have reduced its visit rate to protect its resources. As you restore stability, the crawler will naturally increase its activity if it perceives the site as reliable again.
Monitoring the crawl frequency graph in the platform is a key indicator of your recovery progress. When you see the frequency line start to rise, it suggests that the engine is regaining trust in your server’s availability. Maintain a steady publishing rhythm, as this provides a reason for the spider to continue visiting regularly after the security incident has been resolved.
Why is the crawl diagnosis report important?
The crawl diagnosis tool is the most reliable way to confirm that your fixes worked. It allows you to fetch a URL as the spider and view the server response directly. If the tool displays a successful fetch, it indicates that the path is clear for your pages to return to the index.
Using this tool prevents guesswork. If the server returns a 403 or 500 error during the diagnostic check, you know immediately that something remains misconfigured. By testing key landing pages, you ensure that the spider can see the clean content you have worked to restore, which is vital for the re-indexing process.
Never assume a site is fixed just because it looks normal in a browser. The diagnostic tools in the search platform provide the only source of truth regarding how the engine sees your site architecture.

How Alien Road applies this process
At Alien Road, we follow a strict protocol when managing hacked accounts. We start by performing a full server audit to confirm the integrity of the files. We then use the crawl diagnosis feature to see exactly what the spider sees when it attempts to visit a page. This allows us to confirm if the site is clear of errors before we submit the final request to the search engine.
For a typical client, we treat the recovery as a multi-stage project. We identify the breach, purge the malicious data, and then perform a deep technical audit of the sitemap and robots.txt. By aligning our technical work with the platform’s diagnostic reports, we ensure that the re-indexing request is backed by evidence of a healthy, secure, and accessible website.
- Audit the entire file structure for unauthorized modifications or unknown files.
- Run a crawl diagnosis to ensure the spider receives a 200 status code on all critical pages.
- Check index volume trends to verify that the site is returning to its baseline performance.
- Update the sitemap to ensure it contains only clean, canonical URLs that are free of any malicious redirects.
How to prevent future indexing issues
Prevention is the best way to maintain your position in search results. Implementing a strong update policy and using reliable, professional hosting helps keep your site away from potential threats. Regularly reviewing your crawl exception report in the platform will alert you to any access issues before they lead to a significant drop in your index volume.
Consistent monitoring and maintenance turn security from a crisis into a standard operational task. Ensure that you have backups of your clean state and that you are checking the crawl diagnosis logs at least once a week. This proactive stance ensures that if a minor issue arises, you can address it before it affects your ranking or indexing status.
Where to start this week
Begin by downloading your crawl exception report to identify if the spider is still encountering DNS errors or connection timeouts. Prioritize fixing any access issues today, as these prevent the crawler from seeing your security improvements. Once access is restored, check your publishing frequency to ensure the crawler has a reason to return to your site consistently.
