As I keep saying any content that people are searching for worldwide will help your site seo that in turns give your site authority and that will help your local search.
what are people searching for? adwords will tell you that. below are some post names on one of my blogs, these are real keywords that people search for. to get traffic you need to provide content that matches these type of keywords. you cant know what people in your local area search for, but google never suggests "carpet cleaning town" apart from london or other big city putting all your eggs in the towns names means that your missing out all the many that are being used.
Marketing is about meeting a need and you have tools that tell you what that need is. adwords is the tool for finding out what people are searching for, why do you think google is withholding keywords in searches? because information is worth money, and giving that information to the SEO industry does not help google.
On the subject of needs just look at any carpet cleaning product range, again a list of answers to problems that people have. content about these problems will also help. prochem does not make all those products for fun. just think about this for a moment please,
products are our tools but if you dont have the jobs for those tools your never going to use them. In turn people have say a red wine spillage or urine spot. what are they going to search for? Most carpet cleaners site are very narrow in their message.
SEO is not always about the direct effect it has on your site but the indirect. worldwide search is the indirect way to help local in markets like ours. with keywords you have silos that are related words so carpet cleaning is sub to carpet and all the words below that are what google tells you in adwords. Its our group of keywords. google need to know what relates to what and this is how it does it. why? for ranking the site

I love the term"buying customers" its does not really mater how much or little selling or marketing you do its about the cost of each customer or prospect. below are my real costs
