In some contexts, the term SEM is used exclusively to mean pay per click advertising,[2] particularly in the commercial advertising and marketing communities which have a vested interest in this narrow definition. Such usage excludes the wider search marketing community that is engaged in other forms of SEM such as search engine optimization and search retargeting.
The piece on generating demand for branded queries rather than just product-based ones is particularly interesting here. It sounds as though it'll be more important than ever to have a strong brand in order to succeed (rather than just having a well-optimized site -- and ideally, having the strategic, technical, and creative sides all working together cohesively). Perhaps it's possible that brand exposure through things like answer boxes can still deliver some value too, even if it's difficult to measure, and CTRs are diminished? 

Search engine marketing is the practice of marketing a business using paid advertisements that appear on search engine results pages (or SERPs). Advertisers bid on keywords that users of services such as Google and Bing might enter when looking for certain products or services, which gives the advertiser the opportunity for their ads to appear alongside results for those search queries.
Now in your reconsideration request make sure you are honest and tell Google everything that the prior agency was up too. Be sure to include all Excel information of removed links and say you are going to make an ongoing effort to remove everything negative. It is common knowledge that Google may not accept your first reconsideration request, so it may take a few times.
In order to optimize your SEO results, it’s important to measure the impact of your efforts on web site traffic and lead/sales generation. Google Webmaster Tools can give you important insight into how your site is functioning and identify potential errors you should correct. An analytics tool such as Google’s Universal Analytics is helpful for measuring changes in search traffic as well as tracking visitors interactions with your web site that are a direct result of SEO. Marketing automation tools and call tracking tools can help you tie leads and sales back to SEO.

Audience insight.  The better you know your customers’ pain points, the more tailored your offers will be. The more you’re connected with how they feel, the more succinct and impactful your messaging will be. I can’t think of one aspect of marketing that isn’t strengthened by that depth of audience research.What does organic traffic have to do with it?  When you dissect your traffic, here’s what happens.
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.
