How do your site visitors know that - except for the 2 or 3 that come through from the directory each year?
I've regretted purchasing a directory listing as your directory description replaces your search engine results description. I submitted a wonderful and classy description only for it to be reduced from:
"Widgets UK, offering free nationwide advice for widgets and widgeting. Specialises in widget assistance in the widgeted section of the government."
"offers free nationwide advice."
by a very, very talented young directory editor.
Bravo! Now when I'm listed in the Yahoo search results I look like the badly written one WHEN I DIDN'T WRITE IT! Clickthrough's have never recovered from this bad description even though we have climbed three places to number four in our major keyphrase.
