Types of Site Changes That Can Affect SEO

Organizations make many changes that they do not think will affect SEO, but they have a big impact on it. Here are some examples:

• Content areas/features/options added to the site (this could be anything from a new blog
  to a new categorization system).
• Changing the domain of your site. This can have a significant impact, and you should
  document when the switchover was made.
• Modifications to URL structures. Changes to URLs on your site will likely impact your
  rankings, so record any and all changes.
• Implementing a new CMS. This is a big one, with a very big impact. If you must change
  your CMS, make sure you do a thorough analysis of the SEO shortcomings of the new
  CMS versus the old one, and make sure you track the timing and the impact.
• New partnerships that either send links or require them (meaning your site is earning new
  links or linking out to new places).
• Changes to navigation/menu systems (moving links around on pages, creating new link
  systems, etc.).
• Any redirects, either to or from the site.
• Upticks in usage/traffic and the source (e.g., if you get mentioned in the press and receive
  an influx of traffic from it).

When you track these items, you can create an accurate storyline to help correlate causes with effects. If, for example, you’ve observed a spike in traffic from Yahoo! that started four to five days after you switched from menu links in the footer to the header, it is a likely indicator of a causal relationship.

Without such documentation it could be months before you notice the surge--and there would be no way to trace it back to the responsible modification. Your design team might later choose to switch back to footer links, your traffic may fall, and no record would exist to help you understand why. Without the lessons of history, you are doomed to repeat the same mistakes.
