Yireo – Search Engine Page Cache

You can increase the loading speed of your Magento webshop using Yireo Search Engine Page Cache extension. Search engines and some other sites use web crawling or spidering to update their web content or indexes of your web content. Using your sitemap the crawlers are informed wich pages they have to visit and when to return to that page. This can result in a heavy load on your server when they visit and generate these pages. Blocking search engines to your site to prevent heavy load is out of the question. Using Yireo Search Engine Page Cache the search engines are allowed to crawl your site while preventing high load of the server at the same time. Read on to learn how you can accomplish this ideal situation.

Search engines just read fast content 

When a search engine crawls your website it will follow your provided sitemap and follows the web links on every page it’s allowed to follow. They don’t add a product to a cart nor will it add a product to a wish list. Search engines don’t mind the functionality of your website. They just visits your website to read your content. 

Since search engines don’t care much about dynamic content you should provide them with content as quick as possible. Which means…. provide them with a page from cache if available. And that’s where Yireo Search Engine Page Cache comes in handy. According to their website this extension allows full-page caching only for search engines. 

Using this extension the search bots get served with cached pages if available. Plain HTML output directly from cache. A positive side-effect is that these pages are loaded very fast resulting in a positive impact on your SEO-ranking. Search engines tend to like fast websites.

  • Bing does support the crawl delay in your robots.txt and on top of that you can set a time interval inside Bing Webmaster (Configure my site >> Crawl Control).
