WordPress robots.txt Example

WordPress Robots.txt suggestions by YoastThe robots.txt file is a very powerful file if you’re working on a site’s SEO, but one that also has to be used with care. It allows you to deny search engines access to certain files and folders, but that’s very often not what you want to do. Over the years, especially Google changed a lot in how it crawls the web, so old best practices are no longer valid. This post explains what the new best practices are and why.

Google fully renders your site

No longer is Google the dumb little kid that just fetches your sites HTML and ignores your styling and JavaScript. It fetches everything and renders your pages completely. This means that when you deny Google access to your CSS or JavaScript files, it doesn’t like that at all. My recent post about Google Panda 4 shows an example of this.

This means that the old often heard best practice of having a robots.txt that blocks access to your wp-includes directory and our own old best practice of blocking your plugins directory are no longer valid. This is why, in WordPress 4.0, I to remove wp-includes/* from the default WordPress robots.txt.

Robots.txt denies links their value

Something else is very important to keep in mind. If you block a URL with your site’s robots.txt, search engines will not crawl those pages. This also means that they cannot distribute the link value pointing at those URLs. So if you have a section of your site that you’d rather not have showing in the search results, but does get a lot of links, don’t use the robots.txt file. Instead, use a robots meta tag with a value noindex, follow. This allows search engines to properly distribute the link value for those pages across your site.
