Organic search is extremely important for online retailers, as many studies suggest it drives around 50% of website traffic. When it comes to search engine optimization for eCommerce, marketers get obsessive about testing all methods available to them to try and achieve higher rankings. The logic is very simple: higher positions on SERPs automatically result in higher impressions and a significantly better click-through rate. More people visiting your store should ultimately translate into better conversions and higher revenues.  
In 2007, Google announced a campaign against paid links that transfer PageRank.[29] On June 15, 2009, Google disclosed that they had taken measures to mitigate the effects of PageRank sculpting by use of the nofollow attribute on links. Matt Cutts, a well-known software engineer at Google, announced that Google Bot would no longer treat nofollowed links in the same way, to prevent SEO service providers from using nofollow for PageRank sculpting.[30] As a result of this change the usage of nofollow led to evaporation of PageRank. In order to avoid the above, SEO engineers developed alternative techniques that replace nofollowed tags with obfuscated Javascript and thus permit PageRank sculpting. Additionally several solutions have been suggested that include the usage of iframes, Flash and Javascript.[31]
Your strategy defines your audience, your platform, your content, and even how you measure success. For example, if you sell a product for a young demographic, you may decide that Instagram is the best place to build your brand by using a series of witty pictures with a strong call to action to make a purchase. Alternatively, you may decide to extend the reach of your brand by attempting to break into a new market, such as building a rapport with women, who comprise a large proportion of Pinterest users. Micro-blogging may be an ideal way to give busy business people the bite-sized content they need on their morning commute, while infographics provide visual punch to make a point instantly.
One of the reasons for a traffic drop can also be due to your site losing links. You may be seeing a direct loss of that referral traffic, but there could also be indirect effects. When your site loses inbound links, it tells Google that your site isn't as authoritative anymore, which leads to lower search rankings that in turn lead to traffic drops (because fewer people are finding your site if it's not ranked as highly and more).
Improved Ads and Visual Products. PPC Ads are simply Advertisements. With this, they have full control on what they would like their clients to see first-hand. Contact Number, Location, Services, and Pricing are some of the details that they can easily display to clients. Apart from that, images are now readily available so that clients will be able to get a preview of what they are browsing or buying (for selling sites).
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.
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.
