Big sites really are different. If you can gather your entire Web team into a conference room and explain the new way that we are all going to code our title tags, or if someone on your Web team knows by heart all the keywords that you buy, you don't have a big site. You may have a very successful business, but you are probably already running it well. Big Web sites, on the other hand, are quite a bit harder to run than small sites, especially for search marketing.
Organic search marketing is tough for big sites because there are so many different groups that all have to do the right thing to make it work. Your site might be organized in several different ways, but, regardless, it is divided up into groups, and that's what causes the problem. Depending on the size of your company, you might have all of these problems:
Getting all of these teams/organizations/technologies to work together is not easy, but it can be done. And that's the only path to organic search success.
Paid search in a big company isn't quite as difficult as organic, but it has its own problems. One of the biggest is intramural bidding wars. You may find that several of your product groups are bidding against each other for the #1 result. They are each trying to maximize their paid search sales, but the bottom line is that your company is paying more then is needed for each click.
Big sites have other problems as well, but the biggest problem is that when it's not working, it can be very hard to diagnose what's wrong. And if you do happen to figure out the cause, you need dozens of approvals and "exceptions to the process" to be able to fix it.
First, start with your site's goals (e-Commerce, offline sales, leads, or something else)—you do the same thing for a big site as for a small site. You must count when visitors reach the site's goal to justify the cost of search marketing.
You will need to devote one person (sometimes more for a very big site) to search marketing, so you'll need to show what value will be returned for that cost. That central person or central team will work closely with the rest of your far-flung Web team to teach them, persuade them, and force them (if necessary) to do what is required for search marketing to succeed.
Big sites must do all of the search marketing basics that small sites do, but there are key methods unique to big sites to make sure your whole organization does the right things:
The good news is, if you fix these nagging problems and get your entire extended Web team to follow the right practices, your big site will derive advantages from its well-known name (causing searchers to click on your page), your high-quality content (causing other sites to link to yours), and your larger marketing budget (allowing you broader and deeper paid search campaigns).
