An Introduction to Search Indexes
FAQs
A search index is a compilation of source data that has been analyzed and placed in a searchable order.
Search indexing allows search engines and databases to quickly identify relevant content, data, web pages, etc. without searching every data source available. Search indexes, which contain relevant, summarized, and ordered information about each site, table, or document are what enable search engines and databases to return relevant results in seconds instead of hours or days.
The three key steps to creating a search engine index include crawling, parsing, and indexing. The use of web crawlers is a key aspect in obtaining the relevant data to then be parsed and indexed.
Some examples of database indexing strategies include:
- ESR (Equality, Sort, Range) Rule.
- Query support indexing.
- Result-sorting indexing.
- Selectivity indexing.
Key areas to enhance on your website for better search engine indexing include:
- Content quality.
- Site accessibility.
- Linking.
- Smart content labeling and mapping.
