I have had been writing a series for beginners about configuring W3 Total Cache WordPress plugin to speed up WordPress based sites.
Here is the link to Configuring W3 Total Cache
A quote from my first article
Two reasons to start:
- User Experience. If your site loads faster, your visitors stay happy, your conversions increase, extended number of page views compliment the engagement as well as the increased revenue in case of RPM based ads.
- Search Engine Experience. Sites that load quickly are ranked higher by all search engines. Google has especially mentioned that if your site is optimized and scaled to load faster, then you can expect high SERP rankings.
