You have a migration schedule. It does not follow that Googlebot will take the step. Googlebots also have their own working hours. URL crawling frequency is based on a URL. Google's John Mueller confirmed this, saying: Some URLs are crawled every few minutes, Industry Email List others only every two months, and many somewhere in between. While Google states that many factors affect how often URLs are crawled, in a recent webinar Gary Illyes discussed “planning” and Industry Email List pre-prepared “sets” of URLs for Googlebot to visit. So we know that the planning exists. It is also covered by numerous Google patents on crawling efficiency. It should be noted that crawl frequency is not solely based on PageRank.
Google's Andrey Lipattsev and Gary Illyes recently pointed out in separate webinars that PageRank isn't the only driver of crawling or ranking, Lipattsev saying, "This (PageRank) has become just one thing among many, many things." Importance is important I'm not Industry Email List going to Industry Email List apologize for misusing the word “important” as it has been confirmed that crawl planning is primarily driven by the “importance” of URLs. In fact, Gary Illyes just states that in a recent interview recorded by Virtual Keynote with Eric Enge, and he notes that we shouldn't continue to focus on PageRank as the sole engine for crawling or ranking.
Many Google patents talk about the importance of the page and mention that it “may include PageRank”, but clearly PageRank is only part of it. The importance of the Industry Email List page and the PageRank are therefore not the same, but one (Importance) can include the other (PageRank). What we do know is that important pages are crawled more often. There's the kind of relationship where… when we think something is important, we tend to explore it Industry Email List more frequently. John Mueller So what is “Page Importance”? Of course, Google won't tell us about all of the contributors to Page Importance,
