Regex For SEO!
Regex is the abbreviation for Regular Expression, it is a sequence of characters defining a search pattern in any string. A string can consist of characters, wildcards, space, numbers among others. Regex will be able to capture the pattern and return the full or part of the string result. Regex searches for patterns and not a specific piece of text. This is the reason why you may find that the results are not connected with one another, but when you notice closely, you will realize that it has connection with the string entered giving you a highly filtered response.
For those who haven’t heard of Regex, it is an in-line programming language for text searches where you can enter complex search text, wildcards, partial matches, case insensitive searches among other advanced commands. With Regex you can search for a pattern instead of a bunch of words. This search method is sophisticated delivering a whole lot of search results at the first click.
Regex is a versatile SEO tool as it can be used across Python, JavaScript, etc. Wildcards are used to achieve a pattern match instead of text. Regex can include wildcard character, match for zero or more characters, match for one or more characters, optional characters, nested sub-expressions in parentheses and OR functions. A complex expression can be created using the above operations and this can throw up specific results.
JavaScript allows ‘flags’ after the Regular Expression pattern to improve the outcome of the search. So, what are these flags:
- Get all the matches instead of one using ‘g’
- For case insensitive results use ‘i’
- To activate multimode use ‘m’
- To activate ‘dotall’ mode use ‘s’
- To activate full Unicode support use ‘u’
- To activate sticky mode use ‘y’
