The primary goal is to write content to see that keyphrases are virtually undetectable when read by someone with no knowledge of SEO. One vital step in making this happen is to carefully research and select your keyphrases.

Common Mistake by Every Webmaster:

Many site owners and newbie copywriters make mistakes like replacing every single instance of a generic key term with one of their chosen keyphrases. Doing this in moderation is certainly acceptable, but frequently copywriters get carried away with tragic results.

Example:

Spanish Villas For Rent If you are looking for Spanish villas vacations, search our site for the best deals in Spanish villas. No other Spanish villas site has the selection of premium Spanish villas with the most sought after locations that we have. View some of our Spanish villas pictures or take virtual tours of our Spanish villas today.

Tips to relieve yourself from the mystery of keyword density
1. DON’T use keyphrases to describe your own products or services. Instead, use them to describe what your product or service is not, or what it is similar to or what it is better than.

Example:
Any keyphrase that begins with the word “cheap.” “Cheap insurance,” “cheap sunglasses,” “cheap software” – the list is endless. It’s simply not a good idea to call your own product cheap. Yes, It is true that people are looking for cheap things, but that is because they don’t want to pay a lot. When THEY call your product cheap, it is in relation to price.

But When YOU call your own product or service cheap, it degrades the product or service’s perceived value.

Instead, let others know that your product is NOT cheap. For example:

Unlike cheap travel insurance offered by other underwriters, our policies have provided long-standing, publicly held companies with a history of exceptional customer service. You get affordable coverage and peace of mind.

The phrase is highly relevant to the page, you get to attract lots of visitors, and the copy is set to convince them that “cheap insurance” isn’t what they really wanted after all.

3. Position yourself against your product to show how you are better.

Example: Instead of using “web design for small business” for which you will target the keyphrases like small business, You can target keyphrases like “small business owners” or “small business startups“.

4. Breaking your long keyphrases into a sentence.

Example: for a keyword like “Texas Hill Country real estate”

There is no more beautiful place than the Texas Hill Country. Real estate listings in this area are filled with stunning homes that.

sounds like a very natural sentence.

SEO copywriting should be looked as an art rather than an assembly line task, your content will sound more natural, will convert better and will help prevent further additions to the already overcrowded collection of tortured copy everywhere!

Keyphrase based indexing by search engine spiders – A data-pull model
Researching content from Internet

It just seems like a meaningless exercise in just re-hashing information that’s already available on the web thereby lowering the overall value of your content/article.

But I guess it is still a good practice as Internet is good to use as a starter, so you know which areas you need to research. It is important to ensure that some of your research is either your first-hand research or research using off-line (newspapers, books, magazines).

The net is best seen as a starting point full of hints and tips rather than an actual authority on facts.

The best way to confirm something is true is to go as close to the original source as possible, which may be offline or online. Just go as close as you can to the origin of a story.

Here is an example of how content can come in Authority websites though its not always the case.

“I have a reference phrase that cannot be found any other place on the WWW; however it appeared on a wikipedia after my webpage went online

“Anybody” may change/edit most wikipedia pages at any time.
Should they choose, even injecting false materials?
Unless the person returns that created the text at wikipedia an updates, the incorrect material gets spidered and indexed.”

We all see things differently, and we all describe things differently.

There is rehashing and then there is my interpretation of what I read elsewhere.

The two are not the same.
