One SEO professional asked John Mueller about their CDN (content delivery network) blocking Google Translate, and whether this is bad for SEO.
Their question was: the bot crawling is causing a real problem on their site. They have their CDN blocking unwanted bots. However, this also blocks the Translate This Page feature.
Their questions are, one: is it bad for Google SEO if the Translate This Page feature doesn’t work? Does this also mean that Googlebot is blocked?
And second: is there a way to get rid of the Translate This Page link for all of their users?
John explained that there are different ways, or different infrastructure on their site to access your pages.
On the one hand, there’s Googlebot and the associated infrastructure. John believes that the Translate systems are slightly different because they don’t go through robots.txt, but rather they look at the page directly.
And because of that, it can be that these are blocked in different ways. So in particular, Googlebot is something you can block on an IP level using a reverse DNS lookup, or you can allow it on an IP level.
And the other kinds of elements are slightly different. And if you want to block everything, or every bot other than Googlebot, or other than official search engine bots, that’s up to you.
When it comes to SEO, Google just needs to be able to crawl with Googlebot.
You can test that in Search Console to see if Googlebot actually has access.
And through Search Console, you can get that confirmation that it’s working.
But allowing or blocking the Translate This Page feature, according to John, is not critical for SEO.
