Section 1: Basic Definition
Some basic definitions to start with and please excuse me if it is too simple for an explanation. I will be keeping it purely on organic searches.
People use different phrases to search for a concept, or a product, or a service. These phrases are known as keyphrases. Each keyphrase will contain one or more keyword.
In my opinion keyphrases are like products and all that applies to product management or product marketing applies to keyphrase management and keyphrase marketing, if not direct then certainly in an indirect way. Previously I once had explained the AIM matrix for keyphrases which is a BCG matrix analysis for keyphrase (but lost the original version with server change but still the www has a few copies, you can search for it on web or feel free to contact me).
Section 2: Attributes of a keyphrase
A keyword has many attributes which can be broadly categorized into following attributes:-
Let's take it one by one for indepth understanding
The total number of times a keyphrase is searched across different search engines during a given length of time. For this you can use different online tools. I do not want to give links over here. Search google and you will get it or try [webmasterworld.com...] .
Not each keyphrase is of same relevancy. Some are very directly targeted and not. If I take an example for click fraud company, then "PPC fraud click detection" is more relevant that the keyphrase "Search Engine Marketing" or "SEM". Some searching for SEM may be interested in PPC campagin and thus click farud service but the relevancy factor is low. This highly depends on the product and services offered or rather targeted. This is somehow variably constant as probability of a frequently significant change is very low. You can define a value (e.g. percentage points) to reflect the relevancy.
Note: According to Some experts we can introduce a weighted popularity attribute which is a combination of overall market and relevancy.
No. of searches X relevancy = weighted popularity (will help you find the terms which will best reach the desired audience)
This can be further divided into three points:-
Using these search techniques we can develop an estimated figure for competition. You can come up with an algo here.
* (total backlinks 1,950,000) [search.yahoo.com]
* (these many are internal links from Slashdot.org itself 16,400) [search.yahoo.com]
All these link calculation will give you only an approximate estimate of the overall strength of the top players.
A targeted landing page for each keyphrase (atleast for the major one) is a good practice. Since
f (ranking) = a1 x f (onpage) + a2 x f (offpage) ,
Where f (ranking) = function for Ranking,
f (onpage) = function calculating onpage factor value,
f (offpage) = function calculating offpage factor value and
a1 and a2 are approx weights.
For major keyphrase f (offpage) plays major role as f (onpage) can’t be improved beyond a limit. If you have different landing pages for different search engine (for any reason) then you may face a problem in strengning your position for a high competitive keyphrase.
Section 3: Phases of Keyphrase marketing
There are different phases for keyphrase marketing. I have tried to categorize it into three broader ones, which are:-
Let's study them one by one
The first phase is to discover the keyphrases. As we have explained under "Overall market or popularity", you can use the online tools to discover potential keywords. You can also use Google adwords for keyword discovery. A tracking system can play a very major role in discovering some potential but rare keyphrases like "How to get a mortgage in texas?" You can have a high conversion ratio for such crucial sentences. Tools like google analytics can help in redesigning the landing page for a better conversion ratio.
In order to rank good in search engines you need to invest time into each major keyphrase to bring more traffic and links to the target page. A good analysis can help you with the investment phase. Follow the steps for an investment phase:-
* Step 1: Make a 3x3 matrix with weighted popularity and competition as displayed with high, medium and low columns and rows.
* Step 2: Now fill in the kephrases inside the cells. If your business operates more profitably in Texas compared to California then Texas mortgage has more weighted popularity for your business. Similarly "Well Fargo home mortgage" is very competitive keyphrase but may not be relevant for you. You should start from (high weighted popularity, low competition) and go towards (low weighted popularity, high competition). You can choose a clockwise or anti-clockwise approach to cover cells.
Keep checking the ROI for the keyphrases , sometimes the real data shows a little different graph than our expectations. A tracking system can help you calculate the ROI and redefine your strategies. A consistent feedback and ROI calculation is a must as the market varies so does the competition and the ranking.
I wrote this article when the world was more inclined towards SEO. And this is just an overview, if I get time I will write the marketing aspect of keyphrases with respect to user experiences.
Hope it helps

The total number of times a keyphrase is searched across different search engines during a given length of time
One could read it both ways
As is (the more the better)
or the reverse if (as is) then I will be lost in an ocean of sameness!
This concept is the toughest one to interpret as the result might tell you to stay away from the mass and optimize for the rest or?…
ROI do you mean return on investment if so how could you give a Dollar value to the result or ROI has another signification, alien to me!
Please enlighten me, thanks

Now say for a big keyphrase you might need 10000 links and that makes it $50,000 investment. But if you rank good you can easily get 10,000 odd visitor every month with a conversation ratio of 25%. That makes it 2500 customer every month. Then the profit game starts. Now getting 10000 links will take much time, say one year.
On the other hand there is a small keyword which needs just 100 links giving you 20 converstion every month with an investment of $500 and which can be achieved in a month or two.
In other words these weird calculations will help you decide an optimize investment plan. You can calculate various ROIs. I advice to concentrate on smaller ones first. 70% investment for small keywords and 30% for bigger one every month. After one year you can redefine the strategy based on the progress.
do you agree with following or whats your thought on below
the most generic keywords are the most widely searched, but also the most competitive, and sometimes bring no relevant or partially interested visitor resulting in low conversion rates with high paid keyword. Generally, phrases that most accurately describe specific qualities of a site yield the highest ROI
Question 1: The most generic keywords are the most widely searched.
Answer 1: Yes, most of the times. I have seen exceptions as well in some of the cases.
Question 2: but also the most competitive.
Answer 2: has to be, no doubt about it.
Question 3:and sometimes bring no relevant or partially interested visitor resulting in low conversion rates with high paid keyword.
Answer 3: The catch is with the word "sometimes". Yes it happens sometimes not always. If you are talking about PPC ads then I will have to explain in a different way. I have kept it purely on organic searches.
Question 4:Generally, phrases that most accurately describe specific qualities of a site yield the highest ROI
Answer 4: It gives you a better conversation ratio, even close to 30% sometimes. I calculated ROI on the basis of [(Total visitor * conversion %) / Investment]. General keyphrase gives you more visitor with less conversation ratio, close to 3% sometimes. But remember 4% of 1000 > 30% of 100 :). With respect to organic search there can be variations.

Here high paid keyword does not make sense as it refers to PPC. The conversion ratio will be low but you can count those vistor for other areas like adsense, you can keep checking with your tracking tool and provide them something they want.
What I generally do
I try to put one link (as generic as possible) targetting such visitor if they grow in number. And then optimize the page pointed by the link to increase my revenue.
