Google's search options were designed to allow users to refine their searches. That means users will use these to weed out irrelevant results and better find what they're looking for.

It also means that there is a whole new set of guidelines that search engine marketers will need to think about...or does it? Perhaps it's just the same guidelines, only emphasized to the user more now, thereby making it more important than ever for marketers and web site owners to consider them.

I asked a few search engine marketing experts if they think the options will affect SEO. Here are a few responses I got: Bill Slawski of SEO By the Sea says: "Web Options have the potential to impact SEO by offering a much wider range of ways to find information. Whether or not they will may have to do with whether or not searchers will take the time to click on the 'show options' link, and explore the many new ways that they can find what they may be looking for."

Lee Odden of Top Rank Online Marketing says: "Yes! But it doesn't change the SEO advice we give: fresh content, digital asset SEO..."

"From what I am seeing, the 'search engine optimization' industry is actually turning back around to what it used to be: good old fashioned website marketing," says WebProNews Blog Partner Bill Hartzer, commenting on an SEOmoz post.

"It's not only 'optimizing a website' and 'getting links.' SEO is involving more nowadays: you have to get your site in front of real people and real traffic," he continues. "It's also about using social media marketing techniques, as well. If you're successful in social media you'll be successful in search. If you can get lots of real people to a site then you'll be successful in SEO."

In other words, it's all about optimizing for people. That's all the search engines have ever wanted, and that's all the searchers have ever wanted out of content - to be able to find what they're looking for. It's easier said than done, but all you have to do is help them find you.

To be clear, these are just theories. To the best of my knowledge, there is no concrete answer for how to get ranked in any of these sections. We are after all talking about ranking on Google. I feel like these strategies will only increase your chances of getting found with each option though. It comes down to providing what people are looking for. Search options from Google should be applauded and embraced, because as a content provider and/or a business, you also have more options with regards to which Google results your content will be found in.

Also, keep in mind that paid listings still appear in the results for these options. The same paid listings appear regardless of which option is selected however. And don't forget that users have the ability to use multiple options at the same time. For example, reviews can be listed from most recent to oldest.
