A website is considered search engine friendly if it is optimized for search engines to easily crawl, index, and understand its content. This can be achieved by implementing a number of on-page and off-page SEO techniques, such as:
- Using relevant and unique title tags, meta descriptions, and header tags.
- Creating high-quality, keyword-rich content.
- Using alt tags to describe images.
- Creating a sitemap and submitting it to search engines.
- Creating a robots.txt file to control which pages or sections of the site should not be crawled.
- Building high-quality inbound links to the website.
- Making sure the website has a clean, easy-to-use structure and navigation.
- Optimizing the website's URL.
- Making sure the website is mobile-friendly.
Implementing these techniques can help search engines understand what a website is about, which can in turn help it rank higher in search engine results pages (SERPs).
