Delivering search friendly java script-powered websites (Google io 18 summary)
- 1. Delivering search-friendly JavaScript- powered websites (Google IO 18 summary)
- 3. Create Search Friendly Content 1. Make sure your URL is crawlable - use robots.txt 2. Utilize canonical tag - Tag the source document as canonical 3. Keep the URL clean and unique - Don’t list session information 4. Provide Google with a sitemap - Googlebot has a link to crawl 5. Use history API - no more hashbang (#!) tag 6. Anchor tag and HREF attributes your links - Googlebot won’t recognize it otherwise
- 4. What we know about Googlebot rendering 1. Googlebot uses the Chrome 41 browser for rendering 2. Rendering of JavaScript Websites in Search is deferred 3. Two-phase indexing - First indexing- before the rendering process is complete - Second indexing - after final render - The second indexing doesn't check for canonical tag - The indexability, metadata, canonical tags and HTTP codes of your web pages could be affected.
- 5. There are four types of rendering 1. Client side rendering - Rendering happens on the browser of users or on a search engine. 2. Server side rendering - Rendering happens at your server. 3. Hybrid rendering (the long-term recommendation) - Pre-rendered HTML is sent to users and search engine. Then, the server adds JavaScript on top of that. 4. Dynamic rendering (the policy change) - This method sends client side rendered contents to users while search engines got server side rendered content. - This works in the way that your site dynamically detects whether its a search engine crawler request.
- 7. Tools for implementing hybrid rendering
- 8. You need dynamic rendering if... 1. You have a large and constantly updated website. 2. You rely on a lot of modern JavaScript functionality. 3. Your site has social media or chat application that needs access to your content. You don’t need dynamic rendering if... 1. Googlebot can index your page properly.
- 9. Has Googlebot indexed my website correctly? 1. Fetch as Google on Google Search Console. 2. Run a mobile friendly test. 3. Check the developer console. 4. Run the rich result test.
- 10. Some good news for the future... 1. Rendering will be moved closer to crawling and indexing. 2. Googlebot will be using a more modern browser.
