In the changing world of earning placement on Google.com, Google has been fairly forthright in regards to what it now does not like and will actually penalize a website for doing. What is important to understand is that what Google does not now like was a mainstream SEO and commonly used tactic.
When you see a site that has things like this in the footer:
lemon lawyer Columbus Ohio, lemon lawyer Cleveland Ohio, lemon lawyer Akron Ohio, lemon lawyer Dayton Ohio, lemon lawyer Dublin Ohio, lemon lawyer Wabash Ohio, lemon lawyer Siteville Ohio, lemon lawyer Cincinnati Ohio, lemon lawyer Hamilton Ohio, lemon lawyer Arlington Ohio
AND each one of those phrases is linked to a page on that topic which has very little unique content other than a city location change in the content. You should know that Google has specifically said they DO NOT LIKE content or links formatted or used in this way.
Here is a site to review that is using this type of tactic as an illustration of what not to do.
Google is not penalizing for navigational links in your footer that look like this:

Here are a few sites that I have found that are really bending the rules on Google and may already be receiving a penalty for over optimization:
