Not every single ad will appear on every single search. This is because the ad auction takes a variety of factors into account when determining the placement of ads on the SERP, and because not every keyword has sufficient commercial intent to justify displaying ads next to results. However, the two main factors that Google evaluates as part of the ad auction process are your maximum bid and the Quality Score of your ads.
Writing blogs for your website not only helps with organic search engine optimization, but it provides valuable information for your potential customers and website visitors, among other things. Writing blogs about the industry you service will provide a place for you to insert your keywords plenty of times, while keeping the information relevant and helpful. On top of that, it makes your business look like an industry expert. A well-written blog makes you look more credible because of your level of expertise. Blogs that optimize for keywords will ideally be anywhere from 500 to 2,000 words, but not everyone has the time to crank out blogs that size every week. However, posting shorter blogs still provides value to your client base and potential customers.
Solid analysis on this tough topic Rand. It will definitely be interested to see what in-serp features Google continues to add to keep you on their site as opposed to clicking through to a website.

Google is currently been inundated with reconsideration requests from webmasters all over the world. On public holidays the Search Quality teams do not look at reconsideration requests. See below analysis. From my experience it can take anywhere from 15-30+ days for Google to respond to reconsideration requests; during peak periods it can even take longer.
Google claims their users click (organic) search results more often than ads, essentially rebutting the research cited above. A 2012 Google study found that 81% of ad impressions and 66% of ad clicks happen when there is no associated organic search result on the first page. Research has shown that searchers may have a bias against ads, unless the ads are relevant to the searcher's need or intent 
Optimise for your personas, not search engines. First and foremost, write your buyer personas so you know to whom you’re addressing your content. By creating quality educational content that resonates with you>r ideal buyers, you’ll naturally improve your SEO. This means tapping into the main issues of your personas and the keywords they use in search queries. Optimising for search engines alone is useless; all you’ll have is keyword-riddled nonsense.
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.

Although it may have changed slightly since BrightEdge published its report last year, the data still seem to hold true. Organic is simply better for delivering relevant traffic.
