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. 
Apart from the above mentioned factors, analyzing your competitors’ social strategy, the industry your business falls into, and individual social platforms will also help you in deciding the right social strategy. For instance, last year Facebook reduced the exposure of organic content, so for exponential results on Facebook a brand must go for paid ads.
Webmasters and content providers began optimizing websites for search engines in the mid-1990s, as the first search engines were cataloging the early Web. Initially, all webmasters needed only to submit the address of a page, or URL, to the various engines which would send a "spider" to "crawl" that page, extract links to other pages from it, and return information found on the page to be indexed.[5] The process involves a search engine spider downloading a page and storing it on the search engine's own server. A second program, known as an indexer, extracts information about the page, such as the words it contains, where they are located, and any weight for specific words, as well as all links the page contains. All of this information is then placed into a scheduler for crawling at a later date.
And then if that isn’t enough, what I’ve seen work well is provide some incentives. Have a social contest, a social engagement contest, where people can like content for an opportunity to win say $100 gift certificate, something small scale like that. I myself have been part of these sort of contests before for a number of organizations and see it really amplify the engagement, it gets it in front of your employees’ eyes and thinking about it. And then the beautiful part is after the contest is done, the habit’s built oftentimes. And you’ll notice those same people that were engaging initially for the contest continue to engage with your content and help amplify your message.

Search engine optimization (SEO) campaigns generate organic traffic. The goal of SEO is to improve website ranking for relevant keywords. You want your website to show up on the first page of organic search results – ‘organic’ refers to the middle section of results you see in search engines – for what you’re selling, and you’d probably be considered super human if you did that without organic SEO.

Website owners recognized the value of a high ranking and visibility in search engine results,[6] creating an opportunity for both white hat and black hat SEO practitioners. According to industry analyst Danny Sullivan, the phrase "search engine optimization" probably came into use in 1997. Sullivan credits Bruce Clay as one of the first people to popularize the term.[7] On May 2, 2007,[8] Jason Gambert attempted to trademark the term SEO by convincing the Trademark Office in Arizona[9] that SEO is a "process" involving manipulation of keywords and not a "marketing service."
With organic search, you don’t have to outspend your competitors to outrank them. Your competitors can’t recreate the content experience that you use to drive organic traffic.  This one is major. PPC is easy to replicate and reverse engineer. Many spy tools allow you to dissect paid campaigns to see what’s working and what’s not. You can get insight into what ad creatives generate the most clicks.

Regarding Link Detox, links it diagnoses as Toxic are generally fine as they're either not indexed by Google or have malware/viruses/etc., but I recommend a manual review of any diagnosed as Suspicious. I used it recently to get started cleaning up our backlinks and some legit sites and blogs were under Suspicious simply because they didn't have many links pointing to them.

Using the insight from the Data Cube can serve your blog content creation process in two ways. To begin, you will be able to create posts that align themselves well with what people seek online. This will increase the traffic to your page and help you to boost engagement. Secondly, since you are maintaining a steady stream of high-value posts that are tailored to the interests of your target audience, you will have a far easier time building consistent readership and encouraging people to move through the sales funnel.

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.
Search engines reward you when sites link to yours – they assume that your site must be valuable and you’ll rank higher in search results. And the higher the “rank” of the sites that link to you, the more they count in your own ranking. You want links from popular industry authorities, recognized directories, and reputable companies and organizations.
The monthly volume of searches entered on keywords can be found with a few different methods. If you have a Google AdWords account, you can use Keyword Planner for this step. If you don’t, there are a few free sites out there that will give you similar numbers. Obviously, if a keyword has higher monthly searches you’ll want to keep it in mind. However, that also might mean that it has a higher keyword difficulty, and fiercer competition.
Having large groups of content that all revolve around the same topic will build more relevance around keywords that you're trying to rank for within these topics, and it makes it much easier for Google to associate your content with specific topics. Not only that, but it makes it much easier to interlink between your content, pushing more internal links through your website.
Organic is different. Matching keywords to user intent means you may be present in many searches. The user may find you consistently, and once they get to your site, they are more likely to stay. Organic users are still your best long-term customers. In my experience, they have lower bounce rates and more pages visited, and they are more likely to return.
