Optimise your graphics
Server-based compression software can optimise graphics on-the-fly, but good web designers like to reduce their GIF and JPEG files to optimal sizes before loading them onto the server.
Of course, JPEG files are already compressed, while the new JPEG standard -- JPEG2000 -- has been developed specifically to offer better compression based on the use of wavelet technology.
First generation JPEG files, however, can actually be halved in size without any noticeable loss of image quality. Often you can compress photographic based JPEG images in ratios of 10:1 or even 25:1 with very little loss of image quality. Screeshots and graphics tend to suffer more from compression.
Painting programs, such as Paint Shop Pro from Jasc Software or Adobe PhotoShop, have compression built-in, enabling you to see side-by-side comparisons of compressed and uncompressed images. Using this method it is easy to guess what level of compression will be acceptable -- which is one advantage of compressing images manually instead of relying on server-based systems. It is also very time-consuming if you are dealing with many images, unless you treat them in batch mode.
Also, try using different formats for different types of Graphics, e.g. jpeg or png24 for pictures, gif or PNG8 for buttons and sigs
Minimize the HEAD
Browsers interact with servers in discrete-sized packets. By minimizing the size of your page's HEAD, you can speed your content's initial display. The HEAD must be parsed before the rest of the page is rendered.
Conditional META Tags
To make the search engine spiders happy, while saving space for browsers visiting your site, you can use conditional SSI META tags.
Note if the server detects a "Mozilla" browser (Netscape, IE, or Opera in default mode) it displays no META tags, otherwise it does. Sharp-eyed readers will also note that these meta tags are too long. Try and limit yourself to 200 characters for meta tags.PHP Code:<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<HTML>
<HEAD>
<TITLE>x10Hosting Forums</TITLE>
<!--#if expr="$HTTP_USER_AGENT = /^Mozilla/" --><!--#else -->
<META Name="keywords" Content="authoring web development web

<META Name="description" Content="blablablabalbal">
<!--#endif -->

</HEAD>
Line Length
Browsers seem to like lines of 255 characters or less. Also, some HTML e-mail programs raise an overflow virus warning flag if your lines are too long, so it's best to stick with 200 characters or less for your META tags, and 255 for lines of HTML code.
There's no need to use commas to separate keywords, just use spaces as search engines ignore the commas.
There's lots of other stuff, too. Dreamweaver will optimise it for you, go to Commands > Optimise, and it will remove unnecessary tags.
