| htaccess file | A hidden server configuration file that help to rewrite or redirect URLs on sites running on Apache. |
| null query | Noun phrase. A null query produces no relevant documents as a search result. Alt. A null query may include only documents with null relevance (q.v.). |
| co-occurrence | In SEO, co-occurrence is a loosely used term to described that if certain search terms or phrases occurred to happen simultaneously for numerous searches, a webpage having non of the keywords in its content might rank for the phrase due to the semantic proximity of the content with the search. For example, if a webpage about ?women apparel store might be rank in Googles boutique shop; even though not having the words boutique and ?shop; mainly because of ?women apparel is usually combined with boutique shop in numerous search queries. This term along with ?co-citation? was coined by Rand Fishkin of Moz to predict the future of SEO in November 2012. Perhaps, he has derived the term from linguistics. However, the concept is yet debatable. |
