What are some potential legal issues when manually collecting and analyzing search engine rankings?

One potential legal issue when manually collecting and analyzing search engine rankings is violating the terms of service of the search engine. To solve this issue, it is important to review and comply with the search engine's terms of service, which may prohibit automated scraping or data collection. 

// Ensure compliance with search engine terms of service
// Example: Google's terms of service prohibits scraping search results
// Make sure to manually collect and analyze rankings within the allowed limits

// Code snippet to manually collect and analyze search engine rankings
// Implement a manual process to search for keywords and record rankings
// Ensure that the process does not violate any terms of service

// Example:
$keyword = "example keyword";
$search_results = file_get_contents("https://www.google.com/search?q=" . urlencode($keyword));

// Analyze the search results and extract ranking information
// Example: use regular expressions to find the position of the website in the search results
preg_match('/<cite>(.*?)<\/cite>/', $search_results, $matches);
$ranking = array_search("example.com", $matches) + 1;

echo "Ranking for keyword '$keyword' is $ranking";
