Are you using Wordpress? If so there are a number of plugins meant to help you deal with that.

1. Reduce the size of your site as much as possible. This is usually due to large images.

2. Beyond this, it depends if your site is static or dynamic and if dynamic, what sort of processes are happening when the page is requested. This could be optimizing queries and other backend code.

3. Make sure your site is gzipped.

4. Use some form of caching.

5. Finally, get off shared hosting and onto a proper vps.

If only you can specify more information on your question then it will be possible to provide a good answer, what we can do now is give general options.

1 easy way is to compress the images on the site, you can use Google Pagespeed to check your website, they normally provide a downloadable zip file with what they think are optimized files and these will include images that have been compressed by pagespeed. Just replace them with the images on site and you would have solved one problem.

Try using Autoptimize Plugin if you're using Wordpress, works great for reducing html size e.t.c.

Try to use the least amount of plugins as possible. Minimize the amount of scripts being called & minify those scripts as well.

Caching is a must - how to do it, depends on what platform (if any) you are using. If WordPress, we generally recommend WP Supercache over other plugins, as it simply works, and has little to no issues down the road.

You want to optimize your images as well - compressing them is always good. A great online tool for doing that is https://tinypng.com/

Another thing that many overlook, especially with WordPress is these so called "Security" plugins - they tend to add a gazillion rules to the htaccess, many of which are already controlled at the server level. Each line that has to be processed means it'll be processed before the site is loaded. Proper ordering of the rules & also as little rules as possible is important as well.

Is it possible for you to provide more information about your site?

1- Combine and minify your css
2- Combine and minify your javascript
3- Place your jQuery call in the footer so it loads last
4- Optimize images for the web

Forget all the plugins they just make things worse (mostly). Check your site's loading speed here: SEO Tools, Software and Articles - SEO Site Checkup | SeoSiteCheckup.com

They give you some pretty decent starting points with explanation.

If you are using a WordPress powered website or any database driven or dynamic website... cache is what it is all about, delivering static content when needed and most importantly the way you store that content.

This all boils down to your server configuration, then how you have your chosen website platform, i.e. WordPress or custom platform or simple HTML site and how it stores cached content.

There is no faster way to deliver content than from your server memory, memcache is the way to go... then using a code cache such as OPCache, etc.

Then in the case of WP you would want to use a cache plugin that uses memcache, such as WP-FFPC plugin, recommended... by me.. and a lot of others, simple, uses memcached/memcache and is compatible with NginX, another great way to speed up your sites.

People say WordPress sites are slow, I say they have poorly tuned hosting service, even shared can run a WP site if properly configured... right now we run all of our Tuned Hosting websites on our Tuned Hosting Shared Platform, just to show how fast it is.

This is on our 1st gen platform, next gen will be semi-private distributed data center cloud with 4 data centers in the US... even faster.

So really speed is all about configuration of your webserver, and how you choose to serve content with your site using the tools your server has enabled. So the first step is getting a host that has properly tuned and optimized hosting with:

CentOS/cPanel Latest release
PHP 5.5
NginX/Apache config proxy webserver
Memcache
OPCache
etc.

Then you actually need to use the tools by hooking in your site to them... BTW, caching plugins which cache to disk... DONT ever use, personally they have slowed down more sites than I've seen them speed up... lol.

We ONLY use WP-FFPC to serve our cached content currently.... pulling less than 1 second loads from China, .5 from Germany, .2 from New York to our Chicago Data Center, with no CDN up or other acceleration, purely response from our 1Gbps port server on a 160Gbps network with DDOS protection etc...

Even without image optimization and a bunch of other time consuming tasks... our sites run that fast... check it out and see for yourself.
