Here's some keyword research data that might help you.
Recently, while reviewing collected keyword data, we noticed a large occurrence of the keyword phrase "yellow gold" for December 2011. For the past 10 years, jewelers have told us that white gold jewelry is much more popular choice than yellow gold. Regular keyword research and traffic monitoring seems to agree with what we are told.
That is, until now.
So what are your latest sales figures for white gold vs. yellow gold? Have you noticed?
According to Google Insights for Search, the phrase "yellow gold" is steadily on the rise every year since 2004. Take a look for yourself at this link: http://bit.ly/yellowgold
Eight tall spikes stand out on the graph, which correspond to the last 8 holiday seasons. But that's not what we want you to notice. Instead, take a close look at the level of interest between each spike and you will see it's been rising steadily every year. 2011 is most noticeable.
Now take a look at what's happening with "white gold" over the past 8 years: http://bit.ly/trackwhitegold
That Google Insights for Search graph shows a steady decline in search interest for the last 8 years. Even the spikes during the holiday seasons are lower than that of yellow gold.
Now, don't restock your entire store based on this search data. Instead you should start adding pages to your website that target these phrases of interest:
14k yellow gold
Yellow gold earrings
Yellow gold jewelry
Yellow gold ring
Yellow gold rings
Once you add some content to your site, just sit back and wait for the emails, phone calls, or walk in customers asking specifically for yellow gold. Use your own business experience to judge when the real flip from white to yellow will take place.
Hopefully this is a good advanced warning for our readers. It looks like the trends are about to equalize, then turn back toward yellow gold popularity. Even if this doesn't take place in 2012, there's no harm in adding some yellow gold content to your website now. Obviously someone is searching for it and you might make some extra unexpected cash.
Please let us know in the future if this advice works out for you.
