# URL Matching Rules

The following describes the rules used for defining data matching conditions in page groups, conversions, and event settings.

#### Contains <a href="#bao-han" id="bao-han"></a>

Matches URLs that contain a specific string. For example, when "abc.com" is set as "Contains," URLs like the following will be included:

* `https://abc.com/lp`
* `https://abc.com/company`
* `https://abc.com/company/contact`

#### Does Not Contain <a href="#bu-bao-han" id="bu-bao-han"></a>

Matches URLs that do not contain a specific string. For example, if you want all pages except blog pages, you can set "example.com/blog" as "Does Not Contain."

#### Starts With <a href="#tou-pi-pei" id="tou-pi-pei"></a>

Matches URLs that start with the registered string. Typically used for URLs that contain query parameters.

For example, suppose a specific visitor (id=9982251615) visited the following URL:

`https://www.example.com/checkout.cgi?page=1&id=9982251615`

If the above URL is set as a "Starts With" match, only visits from the user with id=9982251615 will be affected, not visits from other users.

If you want to target all users but only on page=1, you can use the "Starts With" match with the following URL:

`https://www.example.com/checkout.cgi?page=1`

Additionally, if you want to include pages beyond just page=1, you can use the "Starts With" match with the following URL:

`https://www.example.com/checkout.cgi?page`

#### Ends With <a href="#wei-pi-pei" id="wei-pi-pei"></a>

Matches URLs that end with the registered string.

For example, if you register "/test/index.html" as an "Ends With" match, a URL like "<http://www.example.com/s/test/index.html>" would be included.

However, the following URL would not be matched because it does not end with "/test/index.html":

`http://www.example.com/s/test/index.html?wore=xxx`

#### Exact Match <a href="#wan-quan-pi-pei" id="wan-quan-pi-pei"></a>

Matches only when the configured URL is exactly the same as the actual URL.

* Tips: Match parameters: Uses page parameters as conditions, targeting only users with specific parameters. Ignore parameters: Targets all users visiting the page regardless of whether they carry parameters.

#### Regular Expression <a href="#zheng-ze-biao-da-shi" id="zheng-ze-biao-da-shi"></a>

Regular expressions are a method for representing multiple strings that follow a certain pattern.

By using regular expressions, you can define more flexible matching conditions.

**Common Regular Expression Examples**

1. Match a website domain at the beginning and end with a slash or question mark

**Regular expression**: `^https:\/\/www.ptmind.com($|\/$|\/\?.*)`

**Included URLs**: `https://www.ptmind.comhttps://www.ptmind.com/https://www.ptmind.com/?WT.mc_id=xxxx`

**Excluded URLs**: `https://www.ptmind.com/abc`

(Additional examples follow the same pattern)

#### Regular Expression Validation Tool <a href="#zheng-ze-biao-da-shi-yan-zheng-gong-ju" id="zheng-ze-biao-da-shi-yan-zheng-gong-ju"></a>

To verify that a regular expression is written correctly, you can use a tool such as the [Regex Tester](https://c.runoob.com/front-end/854/).
