While optimizing a site for search engines like Google or Bing, caching plays an integral role. As it helps in improving that website speed which is basically a crucial ranking factor.
In this blog we are going to talk about what is caching. Moerover, what are its different types and what strategies we can apply to enhance your SEO by fixing your cache.
What is Caching?
The procedure of storing frequently accessed data temporarily in an area or storage area that’s faster to retrieve, such as a memory or a dedicated cache storage is known as CACHING. The process of content delivery to users speed up because caching enables websites to fetch the same data from one source.
The aim of the caching process is to decrease the server load and improve site’s loading and performance, making SEO efforts in action. Basically, caching happens on two sides: The client side (in the browser) and The server–side performance (in the web server).
How Caching Impacts SEO?
In Google’s Algorithm, website’s speed is an important ranking factor & caching directly makes an impact on site’s speed. The faster your site loads, there are more chances that your site can rank higher in search engines results pages(SERPs). Sites with faster loading speed are assumed to have lower bounce rates and higher engagement rate, which points positive signals to search engines that your site is actively engaging.
For instance, Users are more likely to stay on your site if you’re implementing caching strategies to reduce loading time by doing cache management. This is basically a win-win situation as users not only engage but also navigate through your site and ultimately convert.
Types of Caching Techniques
Different types of caching techniques can help you, take a look below to categorize them:
1. Browser Caching
Certain elements like images, CSS files or Javascript stored in a visitor’s browser for a specific time is called Browser Caching. When your audience revisit your site, minimizing the loading time your browser doesn’t need to reload those elements again. As for the SEO aspect, browser caching can be helpful for enhancing page speed and performance, basically for a revisited audience.
How to Implement Browser Caching: You can make modifications and Cache-Control header in your site’s server configuration file (like .htaccess for Apache servers) in order to implement browser caching. Some specifications like how long acids should be cashed, such as time of one week for images or for style sheets or one month for JavaScript elements.
2. Server-Side Caching
Server-side caching stores entire HTML pages or database queries in cache memory on the web server. This prevents the server from having to regenerate the page or execute database queries every time a user visits your site.
For SEO, server-side caching is critical for reducing server load, especially on high-traffic sites. By serving cached pages quickly, users receive a faster experience, and search engines can crawl and index your site more efficiently. Furthermore, it frees up server resources, allowing your site to scale better.
Types of Server-Side Caching:
- Page Caching: The whole HTML content of the page is stored in the server so that next time on the user’s request of the same page, it can be served directly from cache.
- Object Caching: Stores database query result in memory minimizing the need to retrieve data from the database each time a user makes a request.
- Opcode Caching: Caches compiled PHP scripts to avoid the overhead of recompiling code on each request.
3. Content Delivery Network (CDN) Caching
Multiple network servers strategically located all around the world to deliver content to their audience from their closest server is called Content Delivery Network (CDN). CDNs cache static assets and elements like images, videos or scripts on various servers to make sure faster and easy content delivery.
From the perspective of SEO, CDN caching plays an initial role in minimizing latency rate and enhancing loading time, particularly for global websites. Search engines like Google rewards fast websites so implementation of a CDN can provide better rankings and enhanced user experience.
What benefits CDNs can provide to SEO:
- RCDNced Latency: CDN minimizes the loading time of assets, improving page speed by just caching content on multiple servers.
- Better Uptime: CDN improves site’s reliability and credibility by serving content when your origin server experiences downtime.
4. Reverse Proxy Caching
Reverse proxy caching, a process of intercepting clients requests and caching the responses before sharing them to clients. Tools like Varnish and Nginx are used for reverse proxy caching.
Improved response time and enhanced user engagement can be done by reverse proxies cache content present in your network. This strategy is significantly useful for high traffic sites that generate shape people or dynamic content or rely heavily on databases.
SEO Benefits of Reverse Proxy Caching:
- Reduced Load on Origin Servers: After loading traffic to cached content, reverse proxy caching minimizes the strain on your site’s server and enables faster content delivery.
- Improved Site Performance: User experience can be enhanced by faster page loading, causing minimum bounce rates and better SEO performance.
5. Application Caching
Application caching stores data (such as API responses or computed results) in memory or in a cache store to avoid recalculating the same information repeatedly.
The websites that rely on complicated calculations or on dynamic content, Application caching is very useful for them. Initially minimize server loading and enhance website speed, which directly benefits your SEO efforts by improving performance and user engagement.
