No Restrictions for indexing

 "There are no restrictions for indexing or serving. This rule is the default value and has no effect if explicitly listed." 

In this context, "all" refers to any possible conditions or restrictions related to indexing and serving rules. The statement means that there are no limitations or constraints on what can be indexed or served. It's the default setting, so explicitly mentioning it doesn't change anything.

"What does the term 'noodp' mean when used in a custom robot tag?"

"Noodp" in a custom robot tag refers to a directive that tells search engine crawlers not to use Open Directory Project (ODP) metadata for indexing and displaying snippets of the webpage in search results. The Open Directory Project was a human-curated web directory that provided metadata for search engines. Using "noodp" prevents search engines from using this metadata and instead relies solely on the webpage's own content for indexing and displaying snippets.

If I select "noodp" in the custom robot tag, how will it affect the search results?

If you include "noodp" in the custom robot tag of your webpage, it instructs search engine crawlers not to use Open Directory Project (ODP) metadata for generating snippets in search results. Instead, search engines will rely solely on the content of your webpage to generate snippets.

So, if you check "noodp" in the custom robot tag, search results for your webpage will not include snippets based on Open Directory Project metadata. Instead, the snippets will be generated based on the content of your webpage itself. This can give you more control over how your webpage appears in search results, as the snippets will directly reflect the content you've provided on your webpage.

What are snippets in the search engine?

Snippets are brief excerpts or summaries of a webpage's content that appear in search engine results pages (SERPs). They provide users with a preview of what the webpage is about and help them decide whether to click on the link to visit the page. Snippets are typically generated by search engines based on the relevance of the webpage's content to the user's search query. They can include text, images, or other media, and they aim to provide users with the most relevant and useful information in a concise format.
