After the redesign changed the domain name, do we need to keep the redirection of the old address active?

📅 2026-11-01 👁️ 0

After the domain is changed, should the redirection of the old address always be hanging? The answer is to classify by address, not by overall duration: Old addresses that have received external backlinks or still bring stable traffic should be retained for a long time or even indefinitely; Only old pages brought out by internal links and confirmed to be normally included in the new address can be evaluated for removal after the observation period ends. Common suggestions are to wait for a year before judging, and old addresses with external links continue to hang for a year, until the source indeed changes its mouth.

Why should we worry about the retention period?

The redirect rule itself accounts for maintenance costs: the old domain needs to be renewed, the certificate needs to be valid, and the rules cannot be mistakenly deleted with the version update. But the cost of removing it is more direct - the old address with external links will immediately return an error page, and the link weight and the traffic from these addresses will be cut off at the same time. This kind of loss often appears a few months later from the data, by which time it is difficult to trace back which rule was deleted.

Which addresses cannot be removed

Three types should be retained: first, content with external references, including old links left by industry media, partner pages, and forums; second, landing pages that have brought search traffic, especially column pages and high-conversion pages; third, addresses carrying business entry points, such as event pages, download pages, and contact pages. Conversely, composite addresses with parameters, temporary sorting addresses, and intermediate pages confirmed to have no visitors can be cleaned up after checking the logs.

Do mapping first or cut traffic first

The sequence should be to first establish an address mapping table, then cut traffic, and finally move the internal links. The mapping must cover one-to-one relationships between each old address and the new address, which cannot be converged to the home page of the same level. The pseudo-static rules for the new domain name should be finalized before batch switching, otherwise, if the rules are changed, the established mappings will need to be redone. The internal links should then be replaced site-wide to point to the final address, and the old domain names in navigation, single pages, and the main text should be cleaned up in one go, so that pages do not continue to reference old addresses.

The cost of redirect chains

Jump from the old address to the intermediate address, and then to the final address. This chained jump dilutes the signal and slows down loading, and the crawling end has to spend more requests on the same path. The correct approach is to flatten the multi-level chain into a one-step direct jump, and at the same time, point the anchor text in the main text to the new address, so that the in-site links no longer rely on the jump of the old address to work.

Remove the previous checklist

First check the log and tool data: whether the old address still has external references, whether there are still incoming sessions; then confirm that the new address has been included normally and the old address has not been listed in the sitemap; finally, keep a backup of the fallback rules for convenience in case of immediate recovery when an error is discovered.

Common questions

Is a one-year retention a strict deadline?No, the judgment basis is whether the address is still receiving external links and traffic; addresses with external links are recommended to be retained indefinitely.

Can an old domain name be parked without any attention?It is not recommended, as the domain name may be registered by others after expiration, and historical external links may point to unfamiliar sites.

Will removing redirection affect the inclusion of the new domain name?A stable new address usually is not affected, but incorrectly removing an external link address can cause irreversible losses, and cleaning up needs to be done item by item.

Are there any old links within the site that need to be concerned about?It is important, as internal references will cause the crawler to repeatedly take redirection paths; it can be replaced with the final address throughout the site.

The crawl budget usually only becomes a bottleneck on large websites or websites with high frequency updates, small stations should first clearly see the total number of daily crawl requests and the average response time in the search console, then deal with these three types of waste: broken links, redirect chains, and bulky site maps, and the real problem of most small stations is not the quota, but the inclusion and content.

The average click-through rate dropped by about 20%, coming from the mean comparison of ten thousand-level keyword samples, which is the relative difference between the baseline with overview and without overview, and cannot be taken as the decline of a single site directly. Single-site attribution is more suitable for viewing the traffic of brand words and non-informational intent, the conversion process after entering the site, and the structural changes after retaining the control period, with the click-through rate itself only being one of the signals.

The program itself is free, but the plugins are charged by seat. How do you calculate this cost when selecting?

The cost-free is the software authorization, not the entire cost. The selection should be broken down into four segments for pricing: software license, hosting resources, plugins charged per person or per site, and upgrade backup and other maintenance labor. The larger the team, the more sites, the more obvious the difference in seat fees and hosting fees, and the total account should be calculated based on the same number of people and the number of sites when comparing.

The screening conditions generate a large number of similar pages, whether to block crawling first or block indexing first.

The screening page should first determine whether the waste is the crawling quota or the inclusion quota: the address combination is still being repeatedly requested, which belongs to the crawling side issue, and can be收敛 using robots rules; the page has been crawled and entered into the inclusion before talking about indexing, the handling of whether to index should be canceled indexing or merge the standard address into the main page, blocking crawling itself will not cancel the existing inclusion.

Where is the difference in construction costs between static pages and dynamic sites, and who has higher post-maintenance costs?

The price range of static sites during the construction period is lower, while dynamic sites are expensive in terms of backend, database, and security patches; during the operation period, the situation is reversed, where the content update of static sites depends on technical intervention, and dynamic sites require continuous upgrades and backup work. Sites with frequent updates are more suitable for content systems with backend and scheduled publishing, separating the update actions from the development time.

After a website is attacked, it is necessary to restore the backup, should the vulnerability be patched first or the data be restored first?

The order of disposal is to first cut off the entry that can be reused again, install the affected programs and extensions, and then recover from a known good backup. Restoring data will bring back the time points with backdoors, and the repeated infections are mostly caused by this. After recovery, it is also necessary to check the accounts, scheduled tasks, and modified files, and confirm whether the deleted content still stays in the recycle bin.

The proportion of AI crawler interception changed between two months, is it changed by the default value of the platform or the webmaster?

The same batch of domain names has changed the proportion of AI crawler interception in two months, most of which come from the launch of platform default values, not from webmasters changing configurations one by one. By looking at the direction of change, it can be distinguished: the displacement is concentrated on the training and proxy sides, while the search class has not moved much. When comparing, first lock the same caliber and the same industry level, and then confirm the configuration of robots files, platform classification switches, and in-site exit one by one, changing one and measuring one to attribute.
