Finding the best keywords for websites is the most important aspect of search engine optimization and marketing.
If website owners' keyword selection does not include one of the most searched for keywords or keyword phrase, or has no relevancy to their websites, then any keyword optimisation work will be pointless; because it won’t result in targeted traffic.
It's possible to get a top ranked position - but if no one is searching for the website keywords, then it will all be in vain.
About 90% of the web population find what they want using internet search engines, using keywords or key phrases, so selecting the right ones for your website, is crucial. The results can be highly targeted visitors, and increased sales and profits for those websites with the highest rankings. But there's much more to search engine optimization:
So let's look at Keyword Optimization
Keyword optimisation is a 'catch-all' phrase combining extensive keyword research: choosing the right keywords and key phrases to accurately reflect the purpose of websites (keyword relevancy); finding the best keywords for their target markets; placing them correctly on web pages to ensure proper context with the targeted keywords; and ensuring acceptable keyword density to match each search engines’ criteria. This combination is just one of the elements of search engine marketing.
Successful online businesses use keyword optimization techniques to achieve high ranking on a search engine and capture website visitors

Search engine optimization also includes Site Refinements such as fixing structural problems, correcting html errors and creating tags. Meta Tags are important if you want to be found by the search engines, and these include your title, keywords and description for each page.

Choosing the Best Keywords and Key Phrases
Choosing the right keywords and key phrases is the backbone of a successful search engine optimization. Your website title, description, and meta tags are some of the areas that should be keyword intensive. Whilst the importance of meta tags is under debate, it is still wiser to add them, for those search engine's that use them to compile their listings.
So the first and most crucial step in a successful approach to the search engines is to identify the best list of keywords and short phrases for your site. Many times, multiple-word keyword phrases are more effective than single keywords
Use specific keywords that accurately reflect your site
Use keywords that reflect your location if you offer a location-specific product or service
The most popular keywords may not be the ones to use, and selecting specific keywords relating to your products and/or services will generate targeted traffic to your website, resulting in increased profits. People frequently misspell words when typing, and your selection should include those words also.
Site Relevancy to keyword queries on search engines
To have the most 'relevance' to a given search term, that term (keyword or key phrase) should be mentioned in several places on each page as well as in the meta tags. Your page will be ranked depending upon how a particular search engine measures your page 'relevancy'.
If you use keywords and phrases that are not related to your actual content, you will be banned by internet search engines
For each web page, your first paragraph is your description; keywords are concentrated within the first 200 words on the page, reading from top to bottom; and there must be a balance of keywords to text, or keyword density.

Keyword Density Analysis has a new Twist
In the past, the next step to improve search engine rankings would be to find the right balance of keywords to text, or keyword density. This is still a critical aspect of Search Engine Optimization, but as search engine technology develops, so their algorithms change to benefit their users, and provide the most relevant results.
Now the algorithms collect information on contextual words related to targeted keywords or phrases, as would be used for natural language flow in everyday use, when writing or speaking. This means that content must be created, organised and used in proper context with the selected keywords or phrases used to optimize your web pages.
It is still necessary to calculate the number of keywords, and frequency of keywords vs. the number of words on your page. For high ranking on a search engine, your keyword density must not be too high or too low, and each search engine uses different values when calculating this factor. It's also necessary to ensure your pages are not 'keyword stuffed' or fall into other search engine no-go areas.
Keyword density is a critical aspect of search engine optimization. Internet search engines ‘spider’ your web pages to measure the relevancy of keywords or key phrases to a given search term; calculate the number of keywords; and calculate the frequency of keywords vs. the number of words on your page (ratio). Along with the latest measure for natural language text.
For high ranking on a search engine, your keyword density ratio should be between 1% and 7%. Different weightings or values are applied by each search engine according to where keywords appear on the page (in headings, page title, body text, comments, etc).
