How can website owners ensure that search engine bots accurately index and display website content?

Website owners can ensure that search engine bots accurately index and display website content by implementing proper on-page SEO techniques such as using relevant keywords, creating unique and descriptive meta tags, optimizing images with alt text, and creating a sitemap to help search engines crawl and index all pages of the website.

<?php
// Sample PHP code for creating a sitemap.xml file

$urls = array(
    'https://example.com/page1',
    'https://example.com/page2',
    'https://example.com/page3',
);

$sitemap = '<?xml version="1.0" encoding="UTF-8"?>';
$sitemap .= '<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">';

foreach ($urls as $url) {
    $sitemap .= '<url>';
    $sitemap .= '<loc>' . $url . '</loc>';
    $sitemap .= '<lastmod>' . date('c') . '</lastmod>';
    $sitemap .= '<changefreq>weekly</changefreq>';
    $sitemap .= '<priority>0.8</priority>';
    $sitemap .= '</url>';
}

$sitemap .= '</urlset>';

file_put_contents('sitemap.xml', $sitemap);
?>
