From the use of plug-ins on your site – blog, depends very much. Many people unfortunately underestimate the importance of good plugins for WordPress. A site with good humor plugins can quickly and accurately indexed by search engines. With the help of plugins you can customize your site as you want. I for example, went through hundreds! plug-ins, read dozens of web pages, while a list of mandatory plugins, which should be on my site.
You can use these plugins on your site, you can use other plugins, but most importantly in the use of plug-ins – not overdo it. If you use too many plug-ins, the site will be slow work. Continuing to be a big load on the server, and can even be such that your site is often down. So it makes sense to turn off unused plugins. And your WordPress site will work quickly as the wind.
