The word "spidered" typically refers to the process of a search engine crawling and indexing a website's pages. However, there are several synonyms that can be used to describe this action. One common synonym is "indexed," which indicates that the search engine has added the site's content to its database. Another synonym is "crawled," which implies that the search engine has systematically gone through the site's pages to gather information. Other possible synonyms include "scanned," "parsed," and "catalogued." While these words all describe the same basic process, they may be more or less appropriate depending on the context and the specific nuances of the situation in question.
