While organic search may drive many times more traffic to your site than paid search, you can use this report to see the quality of traffic driven by each method. For example, if you look atSite Usage statistics, you may see that organic search delivers 20 to 30 times the number of visitors, but those visitors view only half as many pages and have twice the bounce rate. And when you look at Ecommerce statistics, you may see that visitors from paid search have a much higher rate of transactions, along with a higher average value per transaction, and a higher dollar value per visit. If you find that your visitors who arrive via paid search represent a significantly higher value customer, that may be an argument to invest more in paid search.

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.
Additionally, there are many situations where PPC (a component of SEM) makes more sense than SEO. For example, if you are first launching a site and you want immediate visibility, it is a good idea to create a PPC campaign because it takes less time than SEO, but it would be unwise to strictly work with PPC and not even touch search engine optimization.
In short, press request alerts are requests for sources of information from journalists. Let's say you're a journalist putting together an article on wearable technology for The Guardian. Perhaps you need a quote from an industry expert or some products that you can feature within your article? Well, all you need to do is send out a request to a press service and you can wait for someone to get back to you.

BrightEdge research supports that a blended approach is best for delivering high performing content. Not only will combining organic and paid search increase website traffic, but it will offer a bigger return on the investment. Take Retail, Technology and Hospitality industries, for example — organic and paid search combined make up more than two-thirds of their total revenue.
