A web designer at Cre8asite Forums has an interesting predicament. She has a client who has a local store and a headquarters both located in two different states. Would it be bad to put two addresses in the footer of the website? Could it negatively affect organic and local rankings where it previously helped?
Nobody knows for sure. One member suggests that you should not put two addresses in the footer but the other address should be posted somewhere, like on the Contact Us page.
Or you can use Google Trends to see which location is more popular. Ultimately, the visitors come first.
But moderator EGOL says that this is a good question to experiment upon.
You have a chance to do a great experiment here.... run analytics to see what search queries come in for the current state, then tally the google rankings for those queries, and then run rankings for matching queries for the new state.... upload the new footer and see what happens to the ranks.
This reminds me of adding your address to Google's Local Business Center, which can also help.
