Earlier this year, Google's Gary Ill yes said that 30x redirects (301, 302, etc.) do not lead to PageRank loss or dilution. As you can imagine, many SEOs met this claim with skepticism. In a recent Central Office Hours Hangout for webmasters, I asked Google's John Mueller if Phone Number List perhaps the skepticism was because when SEOs experience loss of visibility during migrations, they may not realize- Not that not all ranking-impacting signals are passed to new pages yet. suppose the PageRank has been lost. Mueller's response: Yeah, I mean, anytime you make a bigger change to Phone Number List your website - if you're redirecting a lot of URLs, if you're moving from one domain to another, If you're changing your site structure - then everything it takes time for things to settle down. So we can track that pretty quickly, we can definitely get the signals there, but Phone Number List that doesn't mean it's going to happen overnight. During a migration, Googlebot must collect huge amounts of data to aggregate into logs, mapping, and internal updates, and rankings can fluctuate throughout this process. But on top of that, when Googlebot visits play a fundamental role in fluctuating rankings during a migration, and it can be related to “URL scheduling,” a key component of crawl Phone Number List budget. Crawl budget = host load + combined URL schedule URL scheduling is basically "What does Googlebot want to visit (URL), and how often?" Host load, on the other hand, is based on "What can Googlebot visit from an IP address/host, given server capacity and resources?" Together, these make up the “crawl budget” for an IP address or host. These two elements are always important in Phone Number List migrations. On a 10-page brochure site, you probably won't see any loss of visibility during a site migration. But what if your site is, say, an e-commerce or news site with tens of thousands, hundreds of thousands, or more URLs? Or what if you Phone Number List merge multiple sites into one on the same IP host? For everything to be fully embraced, everything should start at a minimum with at least one full site crawl by Googlebot.
