I. IMAGE RESOLUTION PROBLEMS
All images should have a resolution of 72 dpi for web and email (or 150 dpi for digital publication). Sometimes, you may have an image that is 72 dpi, but is fuzzy or "pixelated." This is most likely because the image has been made larger, without accounting for the resolution. Remember, you can make an image smaller without affecting its resolution, but you cannot make an image bigger and maintain the same quality.
II. SIZE PROBLEMS
1. Incorrect size. Double-check the specs to make sure that the size of your ad is exactly the size it's supposed to be! For all ads, set the document size to the ad's actual size, rather than floating the ad on an 8.5 x 11 pasteboard.
2. Do not include bleeds. Bleeds do not exist in the online world. There is no need to include them in your file.
III. COLOR
RGB is the only acceptable color spectrum for electronic ads. Make sure your document setting is set to RGB and not CMYK. Likewise, if you are using a pre-made Swatch Palette, be sure to convert those swatches to RGB.
