optimizing landing page including pictures

When I check freedom.com.tr with pingdom, the page size is 2.7MB: https://tools.pingdom.com/fpt/#!/bWYllo/https://www.freedom.com.tr/

Are you optimizing your images in a graphics program before uploading them, to reduce them to reasonable file sizes? Your theme (and even WordPress) may use that original file on the website, so if it’s huge, your page will be huge.

The Imsanity plugin can be used to optimize images you have already uploaded as well as ones you upload in the future.

Yes it can! I just used it heavily today on two sites. Great plugin (“Imsanity”). Good idea.

Thanks for hints and the plugin. yes I do optimize images before uploading. but I end up with a large first page. I think my hosting is also a major problem. Website that @vtxyzzy mentioned, says load time of my landing page is about 28 seconds and its size is 2.9 Mb. The freedom.com.tr has almost the same size but its load time is 4 seconds.
I think with this hosting and size, I am gonna loose so many impatient customers!
One of my big problem is that WordPress is using 800*640 image size in slideshow products on my homepage

If the page is too large in file size, you’re not optimizing the images enough, or else something else with a large file size is on the page.

Your images are all of a proper size, you just have a large number of them – over 60 images. Even with an average size of 30KB, you still have 1.8MB of images.

You also have a large number of JS (26) and CSS (24) files.

Every file requires a connection to your server which takes a bit of time. Even with a connection time of 0.3 seconds, you would still spend 15 seconds just connecting for these files.

You should try using a caching program that will minify those files and cache them.

thank you both you guys. Great tips.
dear vtxyzzy would you please say how I can minimize the number of Js and Css files? as far as I am concerned I didin’t add extra codes to the theme and it’s supposed to be a SEO friendly theme (enfold).
Is this maybe because of plugins?

by a caching program you mean some plugins like W3 Total?

Please note that I said ‘minify’, not ‘minimize’. ‘minify’ eliminates extra space and can usually combine multiple files into one.

Search the WP Plugin Directory for ‘minify’. And yes, W3 Total Cache is one caching plugin that should both ‘minify’ and cache your pages.

thank you all specially vtxyzzy
