The Three Principles Of Image Optimization

Written by George Peirson

Are you losing visitors to your web site due to slow page load times? Is your site being penalized becauserepparttar images on your site are too large? Are you able to capture your visitor’s attention inrepparttar 145098 first 10-15 seconds that they are on your site?

All of these problems can be caused by an improperly optimized web page. In other words,repparttar 145099 page loads too slowly and your visitor leaves before you have had a chance to hook them.

Optimizing a page for quick load times can be broken down into 3 broad categories:repparttar 145100 basic coding ofrepparttar 145101 page, scripts that are used onrepparttar 145102 page, and images. Of these three, images that are too large can haverepparttar 145103 most significant impact on load times and therefore haverepparttar 145104 greatest potential for improved page loading times if properly optimized.

A brief primer on image types

There are many image formats in common use on web sites,repparttar 145105 three most popular being GIF, JPEG, and to a lesser extent Flash content. We will be limiting our discussion to GIF and JPEG images, with a specific focus on still images.

Each of these image formats has their strengths and weaknesses. GIF or Graphics Interchange Format was developed by CompuServe beforerepparttar 145106 Internet boom as a way to share images onrepparttar 145107 CompuServe service. Due to limitations with screen resolutions and color depths atrepparttar 145108 time, GIF images were limited to showing up to 256 colors, more colors were imitated by Dithering, a process of foolingrepparttar 145109 eye into seeing one color by using 2 or more sets of color dots spaced too closely forrepparttar 145110 eye to distinguish separately.

Imagine a chessboard with black and white squares. When viewed closely we can distinctly seerepparttar 145111 individual squares, but if we back off far enough we will no longer be able to discernrepparttar 145112 individual squares and instead we will see one large grey square,repparttar 145113 black and white squares merging together in our eyes to form one solid color. This isrepparttar 145114 concept behind dithering.

The JPEG file format onrepparttar 145115 other hand is a newer format that can handle millions of colors easily. The initial drawback to JPEG images is that they do contain many more colors, and each color requires some coding for display, makingrepparttar 145116 file size larger.

Speeding up image load times

The main idea behind making an image load faster is to makerepparttar 145117 file size smaller. This can be accomplished in two ways, you can either makerepparttar 145118 dimensions ofrepparttar 145119 image smaller, or decreaserepparttar 145120 amount of coding that is required to displayrepparttar 145121 image.

The easiest way to reduce an images file size is to reducerepparttar 145122 image’s physical dimensions. In other words,repparttar 145123 smallerrepparttar 145124 image,repparttar 145125 smallerrepparttar 145126 file size. Imagine an image that is a square 80 pixels by 80 pixels. The number of pixels contained inrepparttar 145127 image is 80x80 or 6400 individual pixels. If we reducerepparttar 145128 image size by one half to 40 pixels by 40 pixels we then have 40x40 or 1600 pixels. So reducingrepparttar 145129 image size in half reducesrepparttar 145130 file size to one fourth ofrepparttar 145131 original.

Getting The Most From Traffic Exchanges

Written by Brian Pratt

If you are a new to web site promotion or an experienced campaigner, you should include Traffic Exchanges as part of your marketing plan.

When you join a Traffic Exchange you agree to surf other peoples pages and in return, they will surf yours.

Traffic exchanges have been around for a while now, withrepparttar largest ones numbering subscribers inrepparttar 145097 tens of thousands. So submitting your webpage to a Traffic Exchange will potentially give it exposure to a large number of people.

There are basically two types of exchanges, manual surf and auto surf. Withrepparttar 145098 manual surf exchange you click through websites. The Autosurf site presents pages to you automatically withoutrepparttar 145099 need to click.

Some ofrepparttar 145100 advantages of Traffic Exchanges are as follows:

1. A cheap and often free method of sending traffic to your website. This can help with your page rank

2. The traffic you generate arrives almost instantly

3. Some exchanges allowrepparttar 145101 surfer to choose an ad which is associated with pages they view. This is a good way of testing your copy before you spend money placing it inrepparttar 145102 outside world.

4. Most traffic exchanges allow you to build a down line by referring others to them. You usually get credit for their activity, and over time your traffic becomes almost solely generated byrepparttar 145103 efforts of others.

5. You will be exposed to a lot of products and services you wouldn’t normally see, which means you will have a better appreciation of your market and you will pick up some good ideas about promoting your product.

There are some downsides too:

The people surfing these programs are mainly interested in promoting their own page – not looking at yours. This means that you will need to generate a lot more hits for each sale.

When you start out you can spend long hours generating traffic from your own surfing.

Here are some suggestions for gettingrepparttar 145104 most out of Traffic Exchanges:
