They scrape content, probe for weak&nbsp;spots&nbsp;and&nbsp;waste server resources.&nbsp;A simple way&nbsp;to stop many of them is to use&nbsp;htaccess&nbsp;block&nbsp;user agent rules on Apache servers. This approach blocks requests before WordPress loads, which keeps your site faster and safer. In this guide, you will&nbsp;learn practical&nbsp;htaccess&nbsp;block user agent methods, safe&nbsp;patterns&nbsp;and&nbsp;copy-paste examples you can use right away.&nbsp;<\/p>\n\n\n\n<p>Let\u2019s&nbsp;start with the basics and understand what a user agent is.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-user-agents-are-and-why-they-matter-for-your-website-security-nbsp\"><strong>What user agents are and why they matter for your website security?<\/strong>&nbsp;<\/h2>\n\n\n\n<p>A user agent is a piece of text that&nbsp;identifies&nbsp;the&nbsp;client&nbsp;making a request to your website. It can&nbsp;represent&nbsp;a browser (like Chrome or Safari), a search engine crawler (like Googlebot), a social preview&nbsp;bot&nbsp;or&nbsp;a scraping script. When a request reaches your server, the user agent is usually passed in the&nbsp;User-Agent&nbsp;HTTP header. Your server can log&nbsp;it, analyze&nbsp;it&nbsp;and&nbsp;apply rules based on it.&nbsp;<\/p>\n\n\n\n<p>User agents exist&nbsp;mainly for&nbsp;compatibility and identification. Websites use them to serve content that works well on different devices and browsers. Security systems use them to detect patterns of&nbsp;abuse&nbsp;and&nbsp;analytics tools use them to understand visitor behavior. That said, user agent strings can be faked easily, so user-agent blocking is best used as a practical filter&nbsp;&#8211;&nbsp;not as your only security layer.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-examples-of-common-legitimate-vs-malicious-user-agents-nbsp\"><strong>Examples of common legitimate vs. malicious user agents<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Legitimate user agents often look like full browser signatures or verified crawler identities. Examples include:&nbsp;<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Browsers:&nbsp;<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Mozilla\/5.0 &#8230; Chrome\/&#8230; Safari\/&#8230;&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Mozilla\/5.0 &#8230; iPhone &#8230; Mobile\/&#8230;&nbsp;<\/li>\n<\/ul>\n\n\n\n<p>2.

Scripting tools and libraries:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>python-requests\/2.x&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Curl\/7.x&nbsp;<\/li>\n<\/ul>\n\n\n\n<p>4.

Because&nbsp;.htaccess&nbsp;rules run early, the server can stop unwanted traffic before it consumes significant resources. That is why many site owners rely on&nbsp;<a href=\"https:\/\/www.bluehost.com\/help\/article\/htaccess-tutorial\">apache htaccess block rules<\/a>&nbsp;as part of their baseline protection.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-1-nbsp-using-nbsp-htaccess-nbsp-to-block-malicious-user-agents-for-enhanced-site-security-nbsp\"><strong>1.&nbsp;Using&nbsp;htaccess&nbsp;to block malicious user agents for enhanced site security<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Many malicious bots look for vulnerabilities, scan for known WordPress paths&nbsp;or&nbsp;attempt&nbsp;brute force logins. While user agent strings can be spoofed, many low-effort bots reuse the same identifiers. Blocking those repeated offenders helps reduce noise and lowers your exposure to&nbsp;<a href=\"https:\/\/www.bluehost.com\/help\/article\/application-scanning\">automated scanning<\/a>. This is also one of the most common&nbsp;htaccess&nbsp;examples for security, because it is quick to implement and easy to reverse if needed.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-2-nbsp-using-nbsp-htaccess-nbsp-user-agent-blocking-reduces-server-resource-consumption-nbsp\"><strong>2.&nbsp;Using&nbsp;htaccess&nbsp;user agent blocking reduces server resource consumption<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Scrapers and aggressive crawlers can hit hundreds or thousands of URLs per hour. That consumes CPU, RAM, PHP&nbsp;workers&nbsp;and&nbsp;bandwidth. If your hosting plan is limited, this can slow down the site for real visitors. Using&nbsp;htaccess&nbsp;block&nbsp;user agent patterns can reduce junk requests and help stabilize your performance. If your goal is to block scrapers with&nbsp;htaccess, user agent blocks are a good starting point, especially when combined with rate limiting and caching.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-3-nbsp-seo-effects-of-blocking-bots-with-nbsp-htaccess-nbsp-user-agent-filtering-nbsp\"><strong>3.&nbsp;SEO effects of blocking bots with&nbsp;htaccess&nbsp;user agent filtering<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Good bots (search engines) help&nbsp;indexing. Bad bots inflate crawl noise and can distort analytics. Blocking suspicious bots often improves performance for real users, which can support SEO indirectly. Still, you must be careful. Over-blocking or using broad regex patterns can block legitimate crawlers and hurt visibility. The goal is targeted blocking with careful checks, not random blanket bans.&nbsp;<\/p>\n\n\n\n<p>Before you add any rules, you need to access&nbsp;.htaccess&nbsp;safely and back it up.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-prerequisites-and-accessing-your-htaccess-nbsp-file-nbsp\"><strong>Prerequisites and accessing your .htaccess&nbsp;file<\/strong>&nbsp;<\/h2>\n\n\n\n<p>Editing&nbsp;.htaccess&nbsp;is simple, but small mistakes can break your site. A typo can trigger a&nbsp;<a href=\"https:\/\/www.bluehost.com\/help\/article\/500-internal-server-error-help\">500 Internal Server Error<\/a>. That is why backups matter, especially when you are adding multiple&nbsp;apache&nbsp;htaccess&nbsp;block rules.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-where-the-file-is-nbsp-located-nbsp-bluehost-file-manager-or-ftp-nbsp\"><strong>Where the file is&nbsp;located&nbsp;(Bluehost File Manager or FTP)<\/strong>&nbsp;<\/h3>\n\n\n\n<p>On most Bluehost WordPress installs,&nbsp;.htaccess&nbsp;lives in your site\u2019s root folder, usually:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>public_html\/&nbsp;(common)&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>or the folder for your specific domain if you host multiple sites&nbsp;<\/li>\n<\/ul>\n\n\n\n<p><strong>Bluehost File Manager steps<\/strong>&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Log in to Bluehost.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Open&nbsp;<strong>Hosting<\/strong>&nbsp;or&nbsp;<strong>Advanced<\/strong>&nbsp;(menu labels may vary).&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Click&nbsp;<strong>File Manager<\/strong>.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Go to&nbsp;public_html\/.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>If you do not see&nbsp;.htaccess, enable&nbsp;<strong>Show Hidden Files<\/strong>&nbsp;(dotfiles).&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Open&nbsp;.htaccess&nbsp;in the editor.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p><strong>FTP steps<\/strong>&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Connect using an&nbsp;<a href=\"https:\/\/www.bluehost.com\/blog\/wordpress-htaccess-file-how-to-use-edit\/\">FTP client like FileZilla<\/a>.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Navigate to your&nbsp;website root.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Enable viewing hidden files.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Download&nbsp;.htaccess&nbsp;and edit carefully.&nbsp;<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-how-to-back-it-up-before-editing-nbsp\"><strong>How to back it up before editing?<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Use at least one backup method:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Download&nbsp;.htaccess&nbsp;to your local computer.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Copy it as&nbsp;.htaccess-backup&nbsp;in the same folder.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Paste the existing content into a safe text file.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p>If anything goes wrong, restore the backup&nbsp;immediately.

The most popular approach uses&nbsp;mod_rewrite&nbsp;because it supports flexible matching, including regex. These rules make it easy to&nbsp;deny user agent access&nbsp;when a request includes a known bad user agent.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-basic-syntax-and-code-snippets-nbsp\"><strong>Basic syntax and code snippets<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Here is a clean, standard&nbsp;htaccess&nbsp;block user agent&nbsp;pattern using&nbsp;mod_rewrite:&nbsp;<\/p>\n\n\n\n<p>RewriteEngine&nbsp;On&nbsp;<br>RewriteCond %{HTTP_USER_AGENT}&nbsp;BadBotName&nbsp;[NC]&nbsp;<br>RewriteRule .* &#8211; [F,L]&nbsp;<br>&nbsp;&nbsp;<\/p>\n\n\n\n<p>What this does:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>RewriteEngine&nbsp;On&nbsp;enables rewrite processing.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>RewriteCond&nbsp;checks the&nbsp;User-Agent&nbsp;header.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>[NC]&nbsp;makes it&nbsp;case-insensitive.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>[F,L]&nbsp;returns a 403 Forbidden and stops further rule checks.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p>This is one of the simplest&nbsp;htaccess&nbsp;examples for security&nbsp;because it blocks before your application code runs.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-blocking-one-or-multiple-agents-nbsp\"><strong>Blocking one or multiple agents<\/strong>&nbsp;<\/h3>\n\n\n\n<p>To block more than one, chain conditions using&nbsp;[OR]:&nbsp;<\/p>\n\n\n\n<p>RewriteEngine&nbsp;On&nbsp;<br>RewriteCond %{HTTP_USER_AGENT}&nbsp;BadBotOne&nbsp;[NC,OR]&nbsp;<br>RewriteCond %{HTTP_USER_AGENT}&nbsp;BadBotTwo&nbsp;[NC,OR]&nbsp;<br>RewriteCond %{HTTP_USER_AGENT}&nbsp;EvilScraper&nbsp;[NC]&nbsp;<br>RewriteRule .* &#8211; [F,L]&nbsp;<br>&nbsp;&nbsp;<\/p>\n\n\n\n<p>This format is widely&nbsp;used in&nbsp;apache&nbsp;htaccess&nbsp;block rules&nbsp;because it stays readable and easy to update. It also supports quick expansion when you need to&nbsp;block bad bots&nbsp;htaccess&nbsp;style.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-using-regex-for-pattern-matching-nbsp\"><strong>Using regex for pattern matching<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Regex helps when bots change versions or add extra text to the agent.

Avoid patterns like&nbsp;(bot|crawler)&nbsp;unless you are very&nbsp;sure, because&nbsp;some legitimate bots&nbsp;contain&nbsp;those words. If you want&nbsp;to&nbsp;block scrapers with&nbsp;htaccess, prefer&nbsp;specific terms you saw in your logs.&nbsp;<\/p>\n\n\n\n<p>Here is a practical&nbsp;example&nbsp;you can copy and paste to block common malicious bots:&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-example-blocking-common-malicious-bots-nbsp\"><strong>Example: Blocking common malicious bots<\/strong>&nbsp;<\/h3>\n\n\n\n<p>This section gives a starter list.

If your aim is to&nbsp;block bad bots&nbsp;htaccess&nbsp;style without plugins, this is a reliable starting point.&nbsp;<\/p>\n\n\n\n<p>Blocking works best when you manage it properly, so&nbsp;let\u2019s&nbsp;go over best practices next.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-best-practices-for-managing-user-agents-nbsp\"><strong>Best practices for managing user agents<\/strong>&nbsp;<\/h2>\n\n\n\n<p>User agent blocking works best when you treat it like a living rule set. Monitor,&nbsp;adjust&nbsp;and&nbsp;keep your blocks specific. These best practices help you avoid problems while still using&nbsp;htaccess&nbsp;block&nbsp;user agent&nbsp;rules effectively.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-1-nbsp-monitoring-access-logs-nbsp\"><strong>1.&nbsp;Monitoring access logs<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Logs show you what is really happening.

Add rules slowly, then re-check logs. This keeps your&nbsp;apache&nbsp;htaccess&nbsp;block rules&nbsp;accurate&nbsp;and reduces false positives.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-2-nbsp-avoid-over-blocking-legitimate-bots-nbsp\"><strong>2.&nbsp;Avoid over-blocking legitimate bots<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Be careful with broad blocks.

Target specific strings you&nbsp;observed. That approach is the safest way to&nbsp;deny user agent access&nbsp;only where needed.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-3-nbsp-using-firewalls-cdn-brief-mention-of-cloudflare-nbsp\"><strong>3.&nbsp;Using firewalls\/CDN (brief mention of Cloudflare)<\/strong>&nbsp;<\/h3>\n\n\n\n<p>.htaccess&nbsp;is helpful, but it is not a full security system.

Many site owners combine Cloudflare protections with&nbsp;htaccess&nbsp;block&nbsp;user agent&nbsp;rules for extra control. This layered approach is often stronger than user-agent rules alone, especially when trying to&nbsp;block scrapers with&nbsp;htaccess&nbsp;and reduce abusive crawling.&nbsp;<\/p>\n\n\n\n<p>Now&nbsp;let\u2019s&nbsp;look at Bluehost-specific guidance for advanced&nbsp;.htaccess&nbsp;work.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-bluehost-support-for-advanced-configuration-nbsp\"><strong>Bluehost support for advanced configuration<\/strong>&nbsp;<\/h2>\n\n\n\n<p>Bluehost makes it easy to secure your website at&nbsp;different levels. The best choice depends on your&nbsp;hosting&nbsp;type and your comfort level. For many site owners, Shared&nbsp;hosting&nbsp;and VPS&nbsp;hosting&nbsp;are the most natural fits.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-shared-hosting-with-access-to-htaccess-nbsp\"><strong>Shared Hosting (with access to .htaccess)<\/strong>&nbsp;<\/h3>\n\n\n\n<p><a href=\"https:\/\/www.bluehost.com\/in\/blog\/is-shared-hosting-ideal-for-the-new-entrants-in-online-businesses\/\">Shared&nbsp;hosting<\/a>&nbsp;is&nbsp;a good&nbsp;option&nbsp;for&nbsp;all&nbsp;websites. You still get access to the&nbsp;.htaccess&nbsp;file in most cases. That means you&nbsp;can use&nbsp;htaccess&nbsp;block&nbsp;user agent&nbsp;rules without needing server admin skills.&nbsp;<\/p>\n\n\n\n<p>You can edit&nbsp;.htaccess&nbsp;using:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Bluehost File Manager&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>FTP access&nbsp;<\/li>\n<\/ul>\n\n\n\n<p>This is a practical way to apply&nbsp;apache&nbsp;htaccess&nbsp;block rules quickly. It also helps you deny user agent access to known bad bots. If&nbsp;your goal is to block bad&nbsp;bots&nbsp;htaccess&nbsp;style,&nbsp;Shared&nbsp;hosting&nbsp;gives you a simple path.&nbsp;<\/p>\n\n\n\n<svg version=\"1.1\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" viewBox=\"0 0 1001 300\"> \n\n  <image width=\"1001\" height=\"300\" xlink:href=\"https:\/\/www.bluehost.com\/blog\/wp-content\/uploads\/2025\/03\/Shared-Hosting.png\"><\/image> <a xlink:href=\"https:\/\/www.bluehost.com\/web-hosting \"> \n\n    <rect x=\"86\" y=\"203\" fill=\"#fff\" opacity=\"0\" width=\"128\" height=\"63\"><\/rect> \n\n  <\/a> \n\n<\/svg> \n\n\n\n<p>&nbsp;<br>Still, Shared hosting has limits.

It gives you more control and more dedicated resources. It is a stronger fit if you deal with frequent scraping or spikes. It is also helpful if you want deeper server tuning beyond basic&nbsp;.htaccess.&nbsp;<\/p>\n\n\n\n<p>With VPS Hosting, you can still use&nbsp;htaccess&nbsp;block&nbsp;user agent&nbsp;rules. But you also gain options like:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>More detailed server logging&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Advanced&nbsp;firewall&nbsp;rules&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Tighter performance tuning&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Better handling of high traffic&nbsp;<\/li>\n<\/ul>\n\n\n\n<svg version=\"1.1\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" viewBox=\"0 0 1001 300\"> \n<image width=\"1001\" height=\"300\" xlink:href=\"https:\/\/www.bluehost.com\/blog\/wp-content\/uploads\/2025\/03\/VPS-Hosting-1.png\"><\/image> <a xlink:href=\"https:\/\/www.bluehost.com\/vps-hosting\"> \n<rect x=\"82\" y=\"201\" fill=\"#fff\" opacity=\"0\" width=\"173\" height=\"63\"><\/rect> \n<\/a> \n<\/svg> \n\n\n\n<p>&nbsp;<br>If you often&nbsp;need to block scrapers with&nbsp;htaccess, VPS makes it easier to manage the impact. It gives more room to scale. It also reduces the risk of one bot wave slowing everything down.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-sitelock-nbsp-security-as-an-upsell-for-automated-protection-nbsp\"><strong>SiteLock&nbsp;security as an upsell for automated protection<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Some users want a&nbsp;<a href=\"https:\/\/www.bluehost.com\/blog\/protect-your-website-with-sitelock\/\">automated website security solution<\/a>. They do not want to watch logs or keep updating rules. For them, Bluehost add-ons like&nbsp;SiteLock&nbsp;can be a strong upsell.&nbsp;<\/p>\n\n\n\n<p>SiteLock&nbsp;can help with:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Malware scanning&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Vulnerability checks&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Automated alerts&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>General website protection features&nbsp;<\/li>\n<\/ul>\n\n\n\n<p>It complements&nbsp;.htaccess&nbsp;rules well. You&nbsp;can still use&nbsp;htaccess&nbsp;block user agent&nbsp;to filter obvious bad traffic. Then&nbsp;SiteLock&nbsp;can add automated monitoring&nbsp;on top. This combo is useful if you want to&nbsp;deny user agent access&nbsp;while also getting broader, ongoing protection.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-when-to-contact-bluehost-support-nbsp\"><strong>When to contact Bluehost support?<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Contact support if&nbsp;you:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>See a 500 error after editing&nbsp;.htaccess&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Cannot find the file or save changes&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Suspect a major attack or abnormal traffic spike&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Need help with advanced server settings on VPS&nbsp;<\/li>\n<\/ul>\n\n\n\n<p>Support can help you restore a backup fast.

It cuts scraping, reduces server&nbsp;load&nbsp;and keeps your site faster for real users. Start small, use&nbsp;logs&nbsp;and&nbsp;add&nbsp;htaccess&nbsp;block user agent rules only for agents you trust are harmful.&nbsp;&nbsp;<\/p>\n\n\n\n<p>Test each rule and avoid blocking legitimate search engine bots. If you&nbsp;host on&nbsp;Bluehost,&nbsp;<a href=\"https:\/\/www.bluehost.com\/web-hosting\">Shared Hosting<\/a>&nbsp;is a simple starting point with&nbsp;.htaccess&nbsp;access, while&nbsp;<a href=\"https:\/\/www.bluehost.com\/vps-hosting\">VPS Hosting<\/a>&nbsp;offers more control for advanced needs.
