Setting Up the PHP Script

Requirements for Installing the Script:

  • PHP version 7.0 or higher
  • cURL support
  • A MySQL database

Step-by-Step Guide to Installation

Script Preparation:

First, create a new PHP file named serp_checker.php. This file will be the core of your SERP Checker script.

Writing the PHP Script:

Open the serp_checker.php file and insert the following PHP script:


functionsearchKeywordSERP($keyword, $domain) {

$url = "" . urlencode($keyword);

$curl = curl_init();

curl_setopt($curl, CURLOPT_URL, $url);

curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);

$result = curl_exec($curl);


// Check if the domain is in the search results

preg_match_all('/<cite class="iUh30">(.*)<\/cite>/', $result, $matches);

$position = 0;

foreach ($matches[1] as$index => $match) {

if (strpos($match, $domain) !== false) {

$position = $index + 1;







This script performs a Google search for the specified keyword and scans the results to find the position of a specified domain.

Configuring the Script:

To use this script:

  • Replace $keyword with your desired search term.
  • Replace $domain with the domain you want to check for its position in the SERP.

Example usage:

echosearchKeywordSERP("example keyword", "");

This will output the position of "" for the search term "example keyword" in Google's SERP.

API Key Configuration:

// Add your API key configuration at the top of your script

$apiKey = 'YOUR_API_KEY_HERE'; // Replace with your actual API key

Explanation: If your script interacts with APIs that require keys, such as Google Search API, it's crucial to configure your API key. This snippet shows where to define the API key in your script.

Setting Up CRON Jobs:

# Add this line to your crontab file to run the script every hour

0 * * * * /usr/bin/php /path/to/your/serp_checker.php

Explanation: Automate your SERP checks by setting up a CRON job. This line in the server's crontab will execute serp_checker.php every hour.

Customizing Search Parameters:

Customize your search URL for different search engines or regions

$searchEngine = ''; // Example for Google UK

Explanation: Modify the script for different search engines or regions by changing the search URL. This example sets the script to query Google UK.

How the PHP Script Works

The script operates by sending requests to a search engine and analyzing the returned HTML content. It uses cURL for these requests, mimicking web browser behavior. Key features include its ability to perform real-time monitoring and schedule tasks (CRON jobs) for regular updates. Dive deeper into the functionality here.
