2018 Google Mobile First Index - Speed up Apache & Web for SEO
- 1. Google Mobile First Index Speed up your web / Apache / SEO Emirodgar / https://emirodgar.com - @emirodgar
- 2. Optimize Apache http web server & web
- 3. Check Apache active modules We need access through SSH in order to execute linux commands Check Apache active modules with: ● apache2ctl -M If not activated, we need to turn on expires and headers: ● a2enmod expires ● a2enmod headers After that, we need to restart the server ● service apache2 restart
- 4. Apache .htaccess file Now we need to edit .htaccess file which is located at the root of our site (base www dir). If it doesn’t exist, we can create it through FTP. After that we just need to add some lines in order to speed up our site. We are going to active: ● Cache-control ● GZIP Compression ● Keep alive ● Etag
- 5. .htaccess set cache-control <IfModule mod_expires.c> ExpiresActive On ExpiresByType image/jpg "access 1 year" ExpiresByType image/jpeg "access 1 year" ExpiresByType image/gif "access 1 year" ExpiresByType image/png "access 1 year" ExpiresByType text/css "access 1 month" ExpiresByType text/js "access 1 month" ExpiresByType text/html "access 1 day" ExpiresByType application/pdf "access 1 month" ExpiresByType text/x-javascript "access 1 month" ExpiresByType image/x-icon "access 1 year" ExpiresDefault "access plus 1 month" </IfModule>
- 6. .htaccess set Etag Etag helps to use cache memory in a more efficient way. It works like a digital print, it only changes when a file has changed. FileETag MTime Size

- 15. Compress and optimize HTML
- 16. Compress CSS
- 17. Select CSS used Make sure you only include in your page the CSS styles you are actually using in the site. CSS Used is a Chrome plugin that will select the CSS you need (export & create a new final file). Firefox has similar plugins with the same functionality.
- 19. Compress images We can use one of the several tools we have online: ● https://kraken.io/web-interface ● http://optimizilla.com ● https://compressor.io ● https://tinypng.com
- 20. Use a cookieless subdomain as CDN Let’s create our own CDN (Content Delivery Network). You can also use some service as Cloudflare (free and paid plans available). ● Create a subdomain of your own domain or use another domain ● Load static files as CSS, JS and images from this new access Learn more about cookie free domains.
- 21. Use a cookieless subdomain as CDN - Analytics If your are using Google Analytics, make sure you are not generating cookies on the CDN subdomain. For that, set cookie_domain to none.
- 22. Install modpagespeed You can also install mod_pagespeed in your server. Once installed, learn how to configure it. cd /tmp wget https://dl-ssl.google.com/dl/linux/direct/mod-pagespeed-stable_current_amd64.deb dpkg -i mod-pagespeed-stable_current_amd64.deb
