Time waits for no one—everything ages. 
This can be a good thing, such as with a fine bottle of wine, but age 
isn’t always so kind; if you let items like cars and teeth age without 
proper care or maintenance, they deteriorate and often stop working 
entirely.
This applies to online business material
 as well. There are still people who think you can just put business 
material online and expect it to remain accurate, relevant, and useful, 
but this isn’t the case. Like other aspects of business, such as 
advertising and product lines, online business material needs to be 
regularly updated if it’s going to help a business succeed.
It’s important to pay close attention to
 your SEO and its age. SEO has a shelf life, eventually becoming almost 
useless to your business. While you may not wish to do it, you have to 
be ready to refresh your SEO material so it continues to benefit you and
 your business.
Examine and Evaluate
Updating SEO means having to examine and
 evaluate content on a regular basis. By going through your online 
business results, you can get a feeling of where your SEO is weak and 
where to make the necessary changes.
