Keyword gap between two domains

Compares two domains' organic rankings keyword by keyword. Each row carries keyword_data plus first_domain_serp_element (target1's ranking) and second_domain_serp_element (target2's) with rank_absolute, rank_group and the ranked URL. The classic gap query is: competitor ranks well, you don't — filters: [["first_domain_serp_element.rank_absolute",">",20],"and",["second_domain_serp_element.rank_absolute","<=",10]] with target1 = you, target2 = the competitor (a missing element means that domain does not rank at all). Cost scales with rows; the default 100 is enough for most gap analyses.
