Current web design changes in Google search engine result pages, and more specifically the color used for the background of sponsored ad results, are both interesting and ingenious. The ongoing changes to Google’s home page design are more than a whim for entertainment value, and deserve closer study from a web design and marketing perspective.

The screenshot below taken on 30 Sep 2008 as placed in the background of this collage is being compared to another taken today and almost 2 years later on 3 Sep 2010, and displayed towards the front. You have to be impressed with the web design colors and Google ingenuity as they experiment with the layout of search results year after year. Some web design and layout changes are subtle and hardly noticed yet could have a dramatic impact on effectiveness generating revenue.

Search results appear near the center and down the entire length of the page. Sponsored results are the first 1 to 3 listings and people pay for those slots based on key words or phrases whenever a person clicks and follows those links. The rest of the search results are organic meaning they are selected naturally according to Google algorithms to represent the best and most relevant in importance. Sponsored results have a contrasting color for the background while the natural results match the white on the rest of the page.

The illustration displays 3 graphics in the collage: 2008 search results for “custom cms web designers”, 2010 search results for the same phrase “custom cms web designers”, and a small color chart of the hex codes for the 3 colors used in the page background. Why the phrase: custom cms web designers? That phrase summarizes my job description in 4 words, stats tracking confirms Google sends me traffic for that phrase, and I happened to have that 2 year old screenshot saved to allow this comparison.

In the 2008 results the sponsored ads (A) have a #FFFADD background which is obviously high contrast in a medium shade of yellow (B) compared to the rest of the page #FFFFFF white background (C). The 2010 sponsored ads have a #FBF0FA very light pink background (D) which may appear almost white depending on the viewing angle of your pc monitor. Let’s consider how a near white background of sponsored ads could affect user behavior.

The top natural search results (E) after sponsored ads happen to be my website at #1 and #2 worldwide both years for custom cms web designers. Comparing 2008 to 2010 and from personal experience, I tend to skip past the paid sponsor ads to the first natural results because those get listed based on merit and relevance. On my pc the 2008 background contrast is very obvious yet on the 2010 results the sponsored and natural results all appear to blend in with the overall white background which may make it difficult to tell if there’s 1, 2, or 3 paid sponsor ads.

The “pink” became apparent as my lcd monitor was tilted back and reached approximately 40 degrees, and then very apparent at 45 degrees. Maybe it’s just me, but I keep my monitor angle closer to 15 degrees. If it looks white on your screen use the tilt test to see the actual pink, yet use care you don’t break anything! Notice the contrast of the yellow becomes even more obvious when tilting the monitor, as well.

Google revenue from sponsored ads doesn’t come from simply listing advertisers at the top of search pages. Ad revenue is generated when visitors actually click through to the advertiser’s website. Will the current background color of sponsored ads affect traffic to your website if listed in the top 10 of natural results? It may. If you know seo and your page titles and descriptions are more interesting than paid ads, it may not matter.

Regardless, the ongoing testing of color and layout of their results pages is a fine example of web design colors and Google ingenuity. They could be getting more clicks and revenue from their experiment, yet I wouldn’t be surprised if the background color of Google sponsored ad results changed again, soon, or often.

Footnote: For those skeptics who wonder about my advice for online success with your custom cms web design, note that the #2 result worldwide in 2010 above is the blog post published yesterday revealing the web design secret to online success: add original quality related content often. The concept obviously worked for me. One day after it was published that blog post is #2 worldwide on Google page one for a phrase very important to my core business!
