If you often have a blog walk, I know you always see the 125x125 ad banner. Why 125x125? are another ad format to bored, or a little ad like 125x125 format can catch the eye like a flee to the lamp. this market behavior always seems unpredictable, but maybe i have a few answer!
So where is 125x125 ad power in market exactly? the first is design, you only have a few design with this ad, but if your design really catch the eye. there a big chance. and use some creativity, think outside the box don't think inside just because the this ad shape a box.
Many of sites charge high amounts for a little 125 x 125 ad that is placed in non premium areas of the website. Thus, the ads do not really get the attention they deserve. If you are looking to advertise on these websites because of branding purposes, these 125 x 125 ads might work, but if you are looking for ads that convert these won't unless you get really creative with them.
The ad placed up in left sidebar is ad by entrecard social network (I will tell you later) getting creative they were able to increase their ad's click through rate by 1000%. This shows that ads can be effective if advertisers get creative, but the majority of advertisers just don't spend enough time creating creative ads.
I'd love to hear other people's thoughts on these types of ads, does anybody else have any experience with them that they would like to share? I would also be curious to know how often these ads are clicked on, and / or if they have any measurable branding related benefits.
