Avoid Using Size Specifications On Graphics
Use any of the dozens of Web page design programs and you'll find that they
automatically include HEIGHT and WIDTH values for each graphic on a page.
The upside is that this lets the browser lay out the page faster but the
unspoken dark side is one that you want to be very cautious about: if you
drop in a new version of any graphics on your site once you've used these
specifications, you're forever locked into the size of the original graphic.
I constantly get bit by this and it's very annoying. The better solution;
give yourself complete freedom to design - and redesign - your site as you
wish by omitting the height and width specifications.
One Medium Size Graphic is Faster than a Dozen Separate
A bad tendency of new Web designers is to drop in lots of spot graphics
and to have a row of buttons as separate graphics. It makes design easy,
but slows down your page considerably; each graphic must be sent after a
new transfer negotiation between the client and the server. A larger
image-mapped graphic that encompasses all the small icons or buttons is
considerably faster, or, be a rebel, and consider using text-only tags.
All Online Adverts Should Include a Call to Action
The statistics are pretty well known; if you have a banner advert on the
Internet you're likely to see approximately 1.5% click-through (e.g, if
1000 people see your advert, only 15 of them will click on it to go to
your site). You can improve that considerably by remembering to 1. offer
them something compelling (a bargain is better than a fancy graphic),
and 2. have a call-to-action: somewhere on the banner make sure you
specify 'click here' or 'click me' or similar. It makes a surprising
difference. One final recommendation: a thin blue outline for the
advert reminds people that it's a button that can be clicked.
