Weixin provides an Mini Program internal search feature. Developers can use the sitemap.json or admin console page inclusion switch to set whether the Mini Program page permits indexing by Weixin. if allowed, Weixin will use a crawler to create an index of the page content. When a user's search keyword triggers this index, the Mini Program page may be shown in the search results. When the crawler accesses a Mini Program page, it carries a specific user-agent: mpcrawler and scene value: 1129. Note that if a Mini Program crawler discovers that page data is inconsistent with that displayed to real users, the page will not be indexed.

Specific configuration instructions

1. Page inclusion settings: You can disable indexing for the entire Mini Program in the Mini Program Admin Console > Settings > Basic Settings > Page Inclusion Settings. Details
2. Configuration via sitemap: You can disable indexing for specific pages.

# Configuration via sitemap

The sitemap.json file in the Mini Program root directory is used to configure indexing by Weixin for the Mini Program and its pages.

For details of configuration items, see Mini Program Sitemap Configuration.

Example 1:

{
  "rules":[{
    "action": "allow",
    "page": "*"
  }]
}

All pages are indexed by Weixin by default.

Example 2:

{
  "rules":[{
    "action": "disallow",
    "page": "path/to/page"
  }]
}

The path/to/page page is not indexed, but all other pages are.

Example 3:

{
  "rules":[{
    "action": "allow",
    "page": "path/to/page"
  }, {
    "action": "disallow",
    "page": "*"
  }]
}

The path/to/page page is indexed, but all other pages are not.

Example 4:

{
  "rules":[{
    "action": "allow",
    "page": "path/to/page",
    "params": ["a", "b"],
    "matching": "inclusive"
  }, {
    "action": "allow",
    "page": "*"
  }]
}

The path/to/page pages containing parameters a and b are given priority in indexing and the other pages are indexed. For example:

• path/to/page?a=1&b=2 => Indexed first
• path/to/page?a=1&b=2&c=3 => Indexed first
• path/to/page => Indexed
• path/to/page?a=1 => Indexed
• All other pages are indexed

Example 5:

{
  "rules":[{
    "action": "allow",
    "page": "path/to/page",
    "params": ["a", "b"],
    "matching": "inclusive"
  }, {
    "action": "disallow",
    "page": "*"
  }, {
    "action": "allow",
    "page": "*"
  }]
}

• path/to/page?a=1&b=2 => Indexed first
• path/to/page?a=1&b=2&c=3 => Indexed first
• path/to/page => Not indexed
• path/to/page?a=1 => Not indexed
• All other pages are not indexed

Note: If there is no sitemap.json file, all pages will be indexed by default.

Note: {"action": "allow", "page": "*"} are default rules of the lowest priority. Pages for which "disallow" is not explicitly specified are indexed by default.

# Debugging

In a Mini Program project, when you set a sitemap configuration file (sitemap.json by default), debug information about whether the current page is indexed is displayed on the Weixin DevTools console (the latest version of Weixin DevTools supports index prompts).

Note: The sitemap index prompt is enabled by default. You can disable it by setting checkSiteMap to false in setting of the Mini Program project configuration file project.config.json.
