Some information on Google (and Bing sometimes) and its search engine, gleaned here and there unofficially in recent days, with the program this week some answers to these questions: do all Google robots use the same execution ? Are the noindex and nofollow directives followed or ignored by Google in the event of a redirect? Are vital web cores a priority for small sites?
Here is a small compilation of information provided by official Google spokespersons in recent days on various informal networks (Twitter, Hangouts, forums, conferences, etc.). So “gossips” (rumor) + Google = “Goossips” 🙂
The communication of the search engine being sometimes more or less subject to caution, we indicate, in the lines below, the level of confidence (reliability rate) that we grant to the information provided by Google (from 1 to 3 stars , 3 stars representing the maximum confidence rate) – and not to the source which speaks about it.
| Not all Google bots run sites |
| Not all Google crawlers use the same execution system, and some crawlers don’t even run sites, according to John Mueller. He was responding to a user’s question, who asked if all crawlers use the same rendering system for JavaScript content. For example, for simple site verification, there is no execution. Only bots that need to see page content on desktop and mobile will. |

 “Rendering” is seeing the page as in a browser. And indeed, as John Mueller says, the different Googlebots do not all have the same attributes. Some render to see the display of the crawled page, and others do not, such as the Googlebot Site Verifier or the Googlebot Favicon. If you want more information on crawling, indexing and rendering, this article will enlighten you: |
| The noindex / nofollow directives with redirect |
| A few days ago, William Sears posed the following question to Gary Illyes: “Will the noindex and nofollow directives of a redirecting URL be honored or ignored?”. It then specifies that these directives are in the HTTP header and not in the HTML code. While Gary Illyes was vague, he did suggest that Google would ignore these guidelines if there was a redirect. |

| It’s hard to be sure of the reliability of Gary Illyes’ answer, since he says that on some sites Google will ignore the guidelines, and on others it won’t. We can still reasonably think that the redirect will have more weight than the noindex and nofollow directives in Google’s decision. |
| Core Web Vitals are not a priority for local small businesses |
| John Mueller said that in most cases working on Core Web Vitals was not “vital” for local small businesses. He explains that these companies usually don’t have a lot of pages and therefore Google doesn’t have enough CrUX data for CWVs to negatively impact them. However, he balances his point by saying that even if it should not be a priority, it is important for users that the loading speed is not too long. |

| Reliability rate: |
| It seems logical that Core Web Vitals impact larger sites more. Nevertheless, without being a top priority, small business sites must have pleasant navigation, especially if they want to achieve objectives on the web. Not a priority, but not to be left out either! |
