What you want here is a primary keyword and hopefully a set of related secondary keywords that share the searcher's intent. So the intent behind of all of these terms and phrases should be the same so that the same content can serve it. When you do that, we now have a primary and a secondary set of keywords that we can target in our optimization efforts.
In theory Google doesn't take note of descriptions. [And yet Google highlights keywords in descriptions.] But the greatest effect of a good description is click through rate, which is a ranking factor. So if your description is a good call to action and people click on it then Google will notice and (assuming people don't bounce from the site because the content is no good) your ranking should increase.
You’ll want to use email, blogging, and social media tactics to increase brand awareness, cultivate a strong online community, and retain customer loyalty. Consider sending personalized emails to past customers to impress or inspire them -- for instance, you might send discounts based off what they’ve previously purchased, wish them a happy birthday, or remind them of upcoming events.
There are many reasons explaining why advertisers choose the SEM strategy. First, creating a SEM account is easy and can build traffic quickly based on the degree of competition. The shopper who uses the search engine to find information tends to trust and focus on the links showed in the results pages. However, a large number of online sellers do not buy search engine optimization to obtain higher ranking lists of search results, but prefer paid links. A growing number of online publishers are allowing search engines such as Google to crawl content on their pages and place relevant ads on it.[17] From an online seller's point of view, this is an extension of the payment settlement and an additional incentive to invest in paid advertising projects. Therefore, it is virtually impossible for advertisers with limited budgets to maintain the highest rankings in the increasingly competitive search market.
On April 24, 2012 many started to see that Google has started to penalize companies that are buying links for the purpose of passing off the rank. The Google Update was called Penguin. Since then, there have been several different Penguin/Panda updates rolled out by Google. SEM has, however, nothing to do with link buying and focuses on organic SEO and PPC management. As of October 20, 2014 Google has released three official revisions of their Penguin Update.
SEO techniques can be classified into two broad categories: techniques that search engine companies recommend as part of good design ("white hat"), and those techniques of which search engines do not approve ("black hat"). The search engines attempt to minimize the effect of the latter, among them spamdexing. Industry commentators have classified these methods, and the practitioners who employ them, as either white hat SEO, or black hat SEO.[50] White hats tend to produce results that last a long time, whereas black hats anticipate that their sites may eventually be banned either temporarily or permanently once the search engines discover what they are doing.[51]
How Much of this Guide Should You Read? This guide is designed for you to read cover-to-cover. Each new guide builds upon the previous one. A core idea that we want to reinforce is that marketing should be evaluated holistically. What you need to do is this in terms of growth frameworks and systems as opposed to campaigns. Reading this guide from start to finish will help you connect the many moving parts of marketing to your big-picture goal, which is ROI.
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.
