Closing down for a day

crawling and indexing search results UX

Note: This post is specific to Google's organic web-search. For Google's other services, please check with the appropriate help center (e.g., for Google Shopping) or help forum.

Even in today's "always-on" world, sometimes businesses want to take a break. There are times when even their online presence needs to be paused. This blog post covers some of the available options so that a site's search presence isn't affected.

Option: Block cart functionality

If a site only needs to block users from buying things, the simplest approach is to disable that specific functionality. In most cases, shopping cart pages can either be blocked from crawling through the robots.txt file, or blocked from indexing with a robots meta tag. Since search engines either won't see or index that content, you can communicate this to users in an appropriate way. For example, you may disable the link to the cart, add a relevant message, or display an informational page instead of the cart.

Option: Always show interstitial or pop-up

If you need to block the whole site from users, be it with a "temporarily unavailable" message, informational page, or popup, the server should return a 503 HTTP result code ("Service Unavailable"). The 503 result code makes sure that Google doesn't index the temporary content that's shown to users. Without the 503 result code, the interstitial would be indexed as your website's content.

Googlebot will retry pages that return 503 for up to about a week, before treating it as a permanent error that can result in those pages being dropped from the search results. You can also include a "Retry after" header to indicate how long the site will be unavailable. Blocking a site for longer than a week can have negative effects on the site's search results regardless of the method that you use.

Option: Switch whole website off

Turning the server off completely is another option. You might also do this if you're physically moving your server to a different data center. For this, have a temporary server available to serve a 503 HTTP result code for all URLs (with an appropriate informational page for users), and switch your DNS to point to that server during that time.

1. Set your DNS TTL to a low time (such as 5 minutes) a few days in advance.
2. Change the DNS to the temporary server's IP address.
3. Take your main server offline once all requests go to the temporary server.
4. … your server is now offline ...
5. When ready, bring your main server online again.
6. Switch DNS back to the main server's IP address.
7. Change the DNS TTL back to normal.

We hope these options cover the common situations where you'd need to disable your website temporarily. If you have any questions, feel free to drop by our webmaster help forums!

PS If your business is active locally, make sure to reflect these closures in the opening hours for your local listings too!

Google+: A case study on App Download Interstitials

Google+: A case study on App Download Interstitials

apps interstitials mobile UX

Many mobile sites use promotional app interstitials to encourage users to download their native mobile apps. For some apps, native can provide richer user experiences, and use features of the device that are currently not easy to access on a browser. Because of this, many app owners believe that they should encourage users to install the native version of their online property or service. It’s not clear how aggressively to promote the apps, and a full page interstitial can interrupt the user from reaching their desired content.

On Google+ mobile web, we decided to take a closer look at our own use of interstitials. Internal user experience studies identified them as poor experiences, and Jennifer Gove gave a great talk at IO last year which highlights this user frustration.

Despite our intuition that we should remove the interstitial, we prefer to let data guide our decisions, so we set out to learn how the interstitial affected our users. Our analysis found that:

• 9% of the visits to our interstitial page resulted in the ‘Get App’ button being pressed. (Note that some percentage of these users already have the app installed or may never follow through with the app store download.)
• 69% of the visits abandoned our page. These users neither went to the app store nor continued to our mobile website.

While 9% sounds like a great CTR for any campaign, we were much more focused on the number of users who had abandoned our product due to the friction in their experience. With this data in hand, in July 2014, we decided to run an experiment and see how removing the interstitial would affect actual product usage. We added a Smart App Banner to continue promoting the native app in a less intrusive way, as recommended in the Avoid common mistakes section of our Mobile SEO Guide. The results were surprising:

• 1-day active users on our mobile website increased by 17%.
• G+ iOS native app installs were mostly unaffected (-2%). (We’re not reporting install numbers from Android devices since most come with Google+ installed.)

Based on these results, we decided to permanently retire the interstitial. We believe that the increase in users on our product makes this a net positive change, and we are sharing this with the hope that you will reconsider the use of promotional interstitials. Let’s remove friction and make the mobile web more useful and usable!

(Since this study, we launched a better mobile web experience that is currently without an app banner. The banner can still be seen on iOS 6 and below.)
