Years ago someone turned me onto a cool website.
It was something called , www.DynamicDrive.Com -- I liked it. This is actually a very cool site. You can download navigation, drop downs, clocks, calendars and that sort of thing. I used it. I never thought much about it and my traffic was terrible... keep in mind that at the time I only had one website, which is insane.
So on one hand I got all of these cool sliding nav bars, drop downs and other catchy navigation schemes. But yet, Google cannot see them. If you are going to use these things.... and I do admit, I like the look of them. Make sure you do one simple thing.
This is really going to help your real estate seo on your websites.....
Duplicate the links on your page using HTML links. Web spiders travel through hyperlinks and will look at them and want to index them. You will see a lot of these links appear at the bottom of a lot of websites. This is a great way to stay visible.
Its life and death out there for a lot of us. This little bit of advice could save your business!
