Worked Example
Example: a site can be opened at four addresses – http, https, with and without www. Adding a 301 redirect in .htaccess sends every version to https://www.yoursite.com, so search engines see one preferred URL instead of four duplicates.
Quick Reference Table
| Status code | Meaning | SEO effect |
|---|---|---|
| 200 | OK – page loaded | Indexable |
| 301 | Moved permanently | Passes ranking signals |
| 302 | Moved temporarily | Original URL kept |
| 404 | Not found | Remove or redirect |
| 500 | Server error | Fix quickly |
Glossary of Key Terms
- Sitemap
- An XML file listing the URLs you want search engines to crawl.
- 301 redirect
- A permanent redirect that passes ranking signals to the new URL.
- Minification
- Removing unnecessary characters from code to reduce size.
- HTTP headers
- Information a server sends with every response, such as status and caching.
- Core Web Vitals
- Google's page experience metrics for loading, interactivity and visual stability.
Best Practices
Back up files before editing .htaccess or templates, test changes on a staging site, submit your sitemap in Google Search Console and re-check speed and headers after every major update.
How It Works Behind the Scenes
Depending on the tool, it either processes the code or details you provide, or connects to the URL you enter and reads the public response from that server. The output is then formatted into ready-to-use code or a clear report.
