What are Keyword Matching Thresholds?
Article ID: #000137

The inClick Ad Server utilizes an advanced algorithm for matching the provided keyword from the advertiser to the keyword provided by the search / contextual match system. This algorithm can be further adjusted based on your requirements by adjusting the values for two variables in the /globals/globals_custom.php file:

$action_vars["percent_of_phrase_search_term"] = .45;
This is the percent of the words in the search term that must be contained by the campaign's broad match keyword to trigger a match can be from 0-1, i.e. 50% = .5 and would mean that half (rounded up) of the words in the search phrase must be in the broad match keyword for a match. 0 (zero) means percent of phrase is ignored in this situation.

$action_vars["percent_of_phrase_campaign_keyword"] = 1.0;
This is the percent of the words of the campaign's broad match keyword that must be contained in the search term to trigger a match can be from 0-1, i.e. 50% = .5 and would mean that half (no rounding) of the words in the broad match keyword must be in the provided search phrase. 0 (zero) means percent of phrase is ignored in this situation.

NOTE: These values do not exist in the globals_custom.php file. You will need to add the above parameters to override the system default values.
