Google’s Search Advocate John Mueller shares five ways to prepare for a planned website closure.
Are you planning to close your website for a day or longer? According to advice from Google’s Search Advocate John Mueller, here are five ways to prepare.
Mueller shares this advice in tweets while linking to relevant Google help pages.
Spoiler alert — there’s no good way to close a website temporarily. You should avoid doing it if at all possible.
However, there are things you can do to keep the negative impact to a minimum.
Mueller’s recommendations include:
- Use HTTP 503 status code
- Keep HTTP 503 up for no longer than a day
- Change robots.txt file to return 200 status code
- Prepare for consequences if the site is down longer than a day
- Expect reduced crawling from Googlebot
More detail about these recommendations and how to deal with the negative impact of taking a site offline is explained in the following sections.
1. HTTP 503 Status Code
When taking a website offline, ensure it serves an HTTP 503 status code to web crawlers.
When web crawlers like Googlebot encounter a 503 status code, they understand the site is unavailable and may become available later.
With a 503 code, crawlers know to check on the site again rather than drop it from Google’s search index.
Mueller explains how to check for a 503 status code using Chrome:
2. Keep 503 Status Code No Longer Than A Day
Googlebot will go back to a site after initially encountering a 503, but it won’t keep coming back forever.
If Googlebot sees a 503 code day after day, it will eventually start dropping pages from the index.
Mueller says, ideally, you should keep the 503 status code for a day at most.
3. Robots.txt – 200 Status Code
While pages of a closed website should return a 503 code, the robots.txt file should return either a 200 or 404 status code.
Robots.txt shouldn’t serve a 503, Mueller says. Googlebot will assume the site is entirely blocked from crawling.
Additionally, Mueller recommends using Chrome DevTools to examine your website’s robots.txt file:
4. Prepare For Negative Effects
As we mentioned at the beginning of this article, there’s no way to take a website offline and avoid all negative consequences.
If your website will be offline for longer than a day, prepare accordingly.
Mueller says pages will likely drop out of search results regardless of the 503 status code:
“Hmm.. What if a site wants to close for >1 day? There will be negative effects no matter the option you choose (503, blocked, noindex, 404, 403) – pages are likely to drop out of the search results.”
When you “open” your website again, check to see if critical pages are still indexed. If they’re not, submit them for indexing.
5. Expect Reduced Crawling
An unavoidable side effect of a serving 503 code is reduced crawling, no matter how long it’s up for.
Mueller says on Twitter:
“A side-effect of even 1 day of 503s is that Googlebot (note: all of this is with a Google lens, I don’t know other search engines) will slow down crawling. Is it a small site? That doesn’t matter. Is it giant? The keyword is “crawl budget”.”
Reduced crawling can affect a site in several ways. The main things to be aware of are new pages may take longer to get indexed, and updates to existing pages may take longer to show in search results.
Once Googlebot sees your site is back online and you’re actively updating it, your crawl rate will likely return to normal.
