Why SEO is important

While paid advertising, social media, and other online platforms can generate traffic to websites, the majority of online traffic is driven by search engines.

Organic search results cover more digital real estate, appear more credible to savvy searchers, and receive way more clicks than paid advertisements. For example, of all US searches, only ~2.8% of people click on paid advertisements.

In a nutshell: SEO has ~20X more traffic opportunity than PPC on both mobile and desktop.

SEO is also one of the only online marketing channels that, when set up correctly, can continue to pay dividends over time. If you provide a solid piece of content that deserves to rank for the right keywords, your traffic can snowball over time, whereas advertising needs continuous funding to send traffic to your site.

Search engines are getting smarter, but they still need our help.

Optimizing your site will help deliver better information to search engines so that your content can be properly indexed and displayed within search results.

Should I hire an SEO professional, consultant, or agency?

Depending on your bandwidth, willingness to learn, and the complexity of your website(s), you could perform some basic SEO yourself. Or, you might discover that you would prefer the help of an expert. Either way is okay!

If you end up looking for expert help, it's important to know that many agencies and consultants "provide SEO services," but can vary widely in quality. Knowing how to choose a good SEO company can save you a lot of time and money, as the wrong SEO techniques can actually harm your site more than they will help.

White hat vs black hat SEO

"White hat SEO" refers to SEO techniques, best practices, and strategies that abide by search engine rule, its primary focus to provide more value to people.

"Black hat SEO" refers to techniques and strategies that attempt to spam/fool search engines. While black hat SEO can work, it puts websites at tremendous risk of being penalized and/or de-indexed (removed from search results) and has ethical implications.

Penalized websites have bankrupted businesses. It's just another reason to be very careful when choosing an SEO expert or agency.

Search engines share similar goals with the SEO industry

Search engines want to help you succeed. In fact, Google even has a Search Engine Optimization Starter Guide, much like the Beginner’s Guide! They're also quite supportive of efforts by the SEO community. Digital marketing conferences — such as Unbounce, MNsearch, SearchLove, and Moz's own MozCon — regularly attract engineers and representatives from major search engines.

Google assists webmasters and SEOs through their Webmaster Central Help Forum and by hosting live office hour hangouts. (Bing, unfortunately, shut down their Webmaster Forums in 2014.)

While webmaster guidelines vary from search engine to search engine, the underlying principles stay the same: Don’t try to trick search engines. Instead, provide your visitors with a great online experience. To do that, follow search engine guidelines and fulfill user intent.
