Search engine friendly URLs

Human readable or search engine friendly URLs are the URLs that make sense to both humans and search engines because they explain the path to the particular page they point to.

A few advantages of search engine friendly URLS:

• Letting users know what the URL is about

• Keyword-rich URLs impact SEO (can improve your page rankings on search engines like Google).

• URLs are cleaner, meaningful and descriptive, for example, http://yourblog.com/search/product+name/ looks better than http://yourblog.com/?s=product+name

How to enable search engine friendly URLs?

By default this option is turned off, so here's how you can enable it.

Activate WordPress permalinks. Go to WP Admin → Settings → Permalinks and chose non default option.

Then download and install WordPress Sphinx Search plugin version 3.3 or higher from the WordPress plugin directory.

After installation is complete, go to Settings → Sphinx Search → Search settings (tab) and set "Enable friendly URLs" option to ON.

And many more...

• Sphinx in each widget component. All parts of the plugin now use Sphinx which means no more heavy MySQL full-text search queries. All works extremely fast.

• Improved top searches widget. Lots of new settings have been added to the top searches widget. You can now take more control over what things will be shown on different types of pages on your site.

Frequently Asked Questions

What is the WordPress Sphinx Search plugin?

The WordPress Sphinx Search plugin replaces WordPress’s default MySQL full-text search with Sphinx Search Server, which is especially useful when a WordPress site becomes very large. It indexes posts, pages, and comments, supports flexible search syntax, and includes sidebar widgets for related searches, top searches, and recent search terms.

How does the "freshness and relevance" search mode work?

This mode sorts results by relevance within time segments, so newer relevant posts rank higher than older ones. It prevents stale content from dominating search results — particularly useful for blogs and news sites where recency matters. The mode is enabled by default in version 3.0 and can be toggled in plugin settings.

How does the related search terms widget help SEO?

The widget analyzes page titles and displays relevant search phrases as internal links. These links help search engines discover more pages on your site and help visitors find related content. For example, on a product page, the widget shows the most relevant search terms that include the product name, creating natural internal linking patterns that improve crawlability.

Can I control which search terms appear in widgets?

Yes. Version 3.0 includes full search term management: approve or block individual terms, create blacklists to hide terms containing specific phrases, import your own promotional terms, and export all search data to spreadsheets. This gives you editorial control over what appears in top searches and related searches widgets.
