Note that filters are associated with a certain object in the result array, and thus should be specified accordingly. You can learn more about how to use filters in this help center article.

You will receive the full list of filters by calling this API. You can also download the full list of possible filters by this link.

‌‌As a response of the API server, you will receive JSON-encoded data containing a tasks array with the information specific to the set tasks.

Field name Type Description

        data object contains the parameters passed in the URL of the GET request
        result array array of results

the parameters are grouped by the endpoint they can be used with


Below you will find a detailed description of filters available in DataForSEO Backlinks API endpoints. You can specify up to 8 filters by using the and, or logical operators between the conditions.

Note: in Domain Intersection and Page Intersection endpoints the $key parameter refers to the variable denoting the sequence number of the page indicated in the targets array of the POST request;
for example, if you specify the pages in the POST request as follows:
"targets":[
"https://football.com/news",
"https://fifa.com/updates",
"https://uefa.com/updates"]

the specified pages will be assigned with sequence numbers; e.g. the filter by the “https://fifa.com/updates” page will be assigned a “2” and will look as follows:
"filters": ["2.domain_from","=","news24.com"]

Note #2: in Backlinks Anchors, Domain Pages and Domain Intersection endpoints you may come across empty-titled fields in the referring_links_semantic_locations array, which, however, are also available in filters. These empty fields are denoted as $empty and have the num type.
example:
referring_links_semantic_locations.$empty

Note #3: in the following endpoints, you can filter the results by any top-level domain (TLD) from the referring_links_tld object of the response, but the structure of the filtered field is different:

• in Backlinks Anchors, Referring Domains, Referring Networks, and Domain Pages Summary endpoints, use referring_links_tld.$tld;
• in the Domain Pages endpoint, use page_summary.referring_links_tld.$tld;
• in the Domain Intersection endpoint, use $key.referring_links_tld.$tld.

In all cases, replace the $tld variable with the necessary TLD returned in the referring_links_tld object of the endpoint’s response. Example filter:
"filters": ["1.referring_links_tld.com",">",0]

unlike other fields, referring_links_tld.$tld is only available in filters and cannot be used in the order_by parameter for sorting the results.

Description of the available filters:

Field name Type Description
filters array array of results filtering parameters
filters have the following structure:
[filered_fieldfilter_operatorfilter_value]
you can add several filters at once (8 filters maximum)
if you add more than one filter, you must set a logical operator and, or between the conditions
example:
[["domain_from","=", "dataforseo.com"],"and",[["acnhor","like","%seo%"],"or",["texr_pre","like","%seo%"]]]
        filtered_field str fields that support filtration
you can find all available filtered_field values here

Note: fields with an $empty mark are empty, but their values can still be filtered;
in the fields containing $key, this variable denotes the sequence number of the target indicated in the targets array of the POST request

        filter_operator str operator in the filter
available filter operators:
• if bool: =, <>
• if num: <, <=, >, >=, =, <>, in, not_in
• if str: like, not_like, ilike, not_ilike, in, not_in, =, <>, regex, not_regex
• if array.str: has, has_not
• if array.num: has, has_not
• if time: <, >time should be specified in the format: “yyyy-mm-dd hh-mm-ss +00:00”
example:
2021-01-29 15:02:37 +00:00

if you specify in or not_in operator, the $filter_value should be specified as an array
example:
["rank","in",[1,5]]

regex and not_regex operators can be specified with string values using the RE2 regex syntax;
Note: the maximum number of symbols you can specify in regex and not_regex is 1000;

like and not_like operators require adding % symbol to get accurate results;
example:
["anchor", "like", "%seo%"] return backlinks items that contain “seo” in the anchor field
["texr_pre", "not_like", "%seo%"] do not return backlinks items that contain “seo” in the text_pre field

        filter_value filtering value
values specified in the filter_value should match the format of the specified filtered_field
