Trucos para aumentar la Velocidad en SEO

La velocidad de carga de la página web es un factor muy importante a la hora de lograr un buen posicionamiento.

Si tu página web es un WordPress, te recomiendo el plugin NitroPack, que ha sido la solución más fácil y efectiva para mejorar este factor en mi sitio web.

Si no es un WordPress, hay algunas modificaciones sencillas que puedes hacer en el fichero .htaccess, ubicado en la raíz del servidor para activar la caché y mejorar la velocidad:

# BEGIN WP Rocket v3.2.2
# Use UTF-8 encoding for anything served text/plain or text/html
AddDefaultCharset UTF-8
# Force UTF-8 for a number of file formats
<IfModule mod_mime.c>
AddCharset UTF-8 .atom .css .js .json .rss .vtt .xml
</IfModule>

# FileETag None is not enough for every server.
<IfModule mod_headers.c>
Header unset ETag
</IfModule>

# Since we’re sending far-future expires, we don’t need ETags for static content.
# developer.yahoo.com/performance/rules.html#etags
FileETag None
