Starting small will also help you devise a repeatable process that can then be applied across a wider range of search terms as your list grows over time. If you really want to go pro, keyword management tools like Moz Keyword Explorer or SEM Rush’s Keyword Magic Tool can help you streamline this entire process and will allow you to create lists that include hundreds of keywords. 
3. Mapping keywords to the right landing pages. One way to insure you get the best results from your keyword campaigns is to make sure there is very high relevance between the keywords you use and the associated landing pages. This is a very important principle. What happens when you click on an organic listing or a PPC add from a SERP (search engine results page) and the content has little to zero keywords on that page that you used to search on? Right, you bolt and head back and click on another link. Make sure your landing pages are optimized to handle your keyword traffic to make them relevant.
What is the main messaging of their marketing materials? What common customer problems or goals do they often refer to? Let’s say you’re a pet sitter going through a rival business’ brochure. There is a huge difference between a brochure emphasizing frequent real-time online updates, and another brochure emphasizing pet pampering and grooming. The group of clients who are attracted by frequent real-time online updates are often focused on the safety and welfare of their pets, while those looking for more pampering and grooming services are focused on comfort and appearance.
"My favorite part about voice search is just how clear the intent is in the query. For example, if I typed in 'hotels in the Bahamas', you’d have no idea whether I was looking for a romantic getaway, a singles trip or a family vacation.

Both geo-fencing and geo-targeting can be done on mobile, tablet, computer, or even gaming devices with internet access.  When it comes to deciding which is best for your marketing, think of who your target customer is. If you are interested in advertising to a population of all ages and all interests, geo-fencing is perfect for you.

This section serves as a summary and analysis for all of the research you've done so far. You'll review all the aspects of your competition's business and determine whether they are strengths or weaknesses. List their strengths and advantages under "Strengths" in the worksheet.

Then how can someone afford to pay $54.20 per click if it does not generate profit? The answer is simple: they are spending that money to build a brand and they are not focused on the profitability on that individual click; they are focused on profitability over time and they most likely have a budget assigned to building that brand.
