WordPress is indeed a helpful CMS for beginners, but if you want the website to be optimized as per Google's standards, you should consider hiring a freelancer/ developer who can sort out these things for you. There are several WordPress plugins which affect the website's speed and browsing experience. So I'll recommend you to get it fixed by an experienced developer.

You can minify the JavaScript and CSS errors by using CSS minify plugin. And for optimizing the image reduce the size and use Lazyload plugin.

Thanks guys

. I'll check out those plugins. I wish the Page Speed Insights tool would just tell me simple solutions like that instead of leaving me scratching my head.

Where do you hire a website developer, if I needed to go that route later on? Elance?

Yah, It is normal. But If you minify your html, css, js and resize your web images with lower size then your webpage loading speed will be rise.

Basically, you need to minify HTML, CSS and Javascript. Here is a good article on it: How to improve your website's page speed?

Lots of use of the javascript causes the page load speed error, there are ways you can reduce that make your code working, try to code less for speed optimization.

You need to reduce HTML, CSS and Javascript, Jquery.

System startup packed too many applications,spyware,slow network performance,badly fragment hard drive,hardware problems,poor security software steal your system resources.

This means that you have one or more scripts that must be evaluated before the page can be rendered due to the position of the scripts in the page. There are various ways to avoid this, but perhaps the easiest of them all is to move all the script tags to the bottom of the page, just before the </BODY> tag.

Generally speaking you can help reduce response time by serving less requests / making the server work less. So you could offload static assets to a CDN, for starters. Also make sure you have a caching plugin in Wordpress to serve static pages and also PHP caching such as APC depending on the version of PHP in use.

In the virtual host of the website make sure that you have rules to maximise the caching of the static assets, so that they do not have to be downloaded for each page view after the first one. For this to work well, you must make sure that the URLs for the static assets change when their content changes. So you would add a version number or something to the filenames.

If you don't change JavaScript/CSS often, you can find several "minifiers" or compressors online.

You can use ImageOptim for example to optimise file size of your images with little to no loss in visual quality.

This requires a plugin in Wordpress since the HTML is generated dynamically. Usually caching plugins can also do this.

This depends on the overall design I think
