I think for agencies as far as how we appear in organic search ourselves, we are definitely going to need to leverage all 3 of the solutions you talk about and agencies who haven't branded their products/services are going to have to do that and are going to have to also employ branding strategies. In addition, we have to optimize for other search ares like you say in your point #2 and we must look at optimizing existing content for voice search and answers/featured snippets like you say in point #3.
Earlier I touched on using ultimate guides to shift the awareness of the reader to facilitate a conversion. That’s a solid example. Your content can serve any number of goals including sales, lead generation, etc. You could even use it to warm up a cold audience before you expose them to a paid campaign. It can lower your ad costs and increase your click-through rates. The utility of content is endless. You decide.
Organic marketing, of course, is different from outbound or paid marketing. Outbound marketing seeks to place advertising and promotional content in front of people who are not looking for it. In our era of big data, the ability to target advertising has blurred the line between in and outbound marketing slightly. Paid marketing is good at generating traffic when it is needed. However, organic marketing will continue to provide leads over time without the need to continue to spend on advertising.
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.
