Yes! Google announced that the ranking algorithm including your website page speed.
As the increasing of the mobile visitor nowadays (around 80% of mobile visitor base on one of my client), Google concern about the user experience when visitors click the search result. It was an understandable action that Google include page speed as a factor of SEO.
This is one of our clients for the case study. We added some of the technology for speed optimization and the Avg. loading time decrease from ~10s to within 2s.
We found the Average search ranking also decrease from 37 to 24 within one month.
However, all of us can make the site faster manually. That’s what Google doesn’t like it. The rate of affecting your SEO result is limited. You better work harder both Onsite and Offsite SEO setup.
Also, that is not an easy task to boost your page speed as you think. Both client and server-side problems, hosting configuration, AMP optimization and Minify design.
I have a list of to-do tasks that make your site faster
- Minify CSS / JS
- Reduce Redirect, even you use .htaccess or PHP redirect. which makes an extra loading on your server side.
- Leverage browser caching, which enhance page speed for repeated visitors
- Image compress, most of the time we received an image that larger than 2MB, we can compress to 100-300KB for the output. Also, we suggest the dimension not larger than 3000px for each side, which is good enough for the image quality load on your site.
- Using CDN and AMP technology
Finally, i suggest a useful testing link that can rate your website load time on Mobile. There are suggestions for optimization after test, easy to understand and super easy to use.
