Question

search engines create and determine the order of search results using algorithms, which are

keywords and metatags

human - curated lists

numerical codes

processes or sets of rules

Explanation:

An algorithm is a well - defined set of rules or a step - by - step procedure to solve a problem. Search engines use algorithms (processes or sets of rules) to determine search result order. Keywords and metatags are elements used in web pages for search relevance. Human - curated lists are not algorithms as they are created by humans without a set of automated rules. Numerical codes are just a form of representation and not the definition of an algorithm.

Answer:

processes or sets of rules
