The first one is pretty powerful and pretty awesome, which is investing in demand generation, rather than just demand serving, but demand generation for brand and branded product names. Why does this work? Well, because let's say, for example, I'm searching for SEO tools. What do I get? I get back a list of results from Google with a bunch of mostly articles saying these are the top SEO tools. In fact, Google has now made a little one box, card-style list result up at the top, the carousel that shows different brands of SEO tools. I don't think Moz is actually listed in there because I think they're pulling from the second or the third lists instead of the first one. Whatever the case, frustrating, hard to optimize for. Google could take away demand from it or click-through rate opportunity from it.
Awareness and Branding. Visibility is one thing and being top of the line is another. The more that people see you, the higher your chances of being remembered and that keeps awareness among potential customers. Same goes with branding. Once you start linking your business with certain terms and keywords which are deemed positive for you, its effect will most likely be beneficial for your business and can, later on, lead to a sale.
I agree with the point that a small or medium-sized business will have limits for budget and resources in generating brand search, but I wouldn't say that stops them from potentially producing huge growth there if they do something interesting/innovative etc. I can think of quite a few small to medium sized brands that have more name recognition than larger companies in their space. The challenge is that many of those brands are led by people who are very good at generating marketing and publicity - it's harder for small brands to be able to afford to pay for a top level consultant or agency.
Now, it is not that these sites are not interested in Google users. In fact, they have hired us to help them increase their share. However, they are getting so much traffic from sites like Facebook that it seems there is less urgency about attracting this traffic and less willingness to change the site to meet organic standards. Not long ago, sites would urgently and unquestioningly abide by Google’s standards to court that traffic.
