Good point,The thing with this client is they wanted to mitigate the risk of removing a large number of links so high quality link building was moved in early before keyword research. So it is on a case by case basis, but defiantly a good point for most new clients I work with who do not have pre-existing issues you want to do Keyword Research very early in the process.
At our agency, we work with sites of varying sizes, from very large to quite small, and recently, we have noticed a trend at the enterprise level. These sites aren’t relying as much on Google for traffic any more. Not only are they not relying on Google traffic, but also, the sites are getting less than 10 percent (or slightly more) of their organic traffic from the search giant.
This is a great piece of work for references, lots of info on this, Answer sites have become less and less popular, but the you can really build your name on these sites such as forums, if you are consistent in answering questions frequently. Out of the points you have mentioned, I relay enjoy the "Guest Blogging" point, as this is a win win situation, not just putting out content on other websites, but also welcoming guest on my own site, giving readers a change and a different style of article, as everyone is unique in their own way. I'm actually posting an interview tomorrow with a well known name in the guest blogging. Whichever point one choices from above, consistency is the key, there is no point doing it once, but it should be done on frequently, and over time with patience you will start to see the rewards.
Direct traffic is defined as visits with no referring website. When a visitor follows a link from one website to another, the site of origin is considered the referrer. These sites can be search engines, social media, blogs, or other websites that have links to other websites. Direct traffic categorizes visits that do not come from a referring URL.
