If we follow the example of a dog, you may find that the key phrase “adopt a dog” will bring more visitors because there is a special section on its web site where you give this advice for anyone wanting information about adopting a dog. This page is not of interest to current dog owners, but the possible potential owners of a dog, perhaps not much in number but is your target audience and the overall effect of attracting this niche may be better to attract anyone who is interested in dogs in general. Using its monthly statistics you can check how many click through surveys were conducted and what the words used, carefully consider the unique hits that are most relevant to the topic or content of your web site.

Keyword Density
After you choose the keywords that describe your site and are supposedly of interest to their visitors, the next step is to make your web site “to be rich in keywords and have a good density for your keywords target. The density of keywords is a common measure of how relevant a page.

Generally, the idea is that the higher the keyword density of greater relevance on the outcome of research in relation to the page. The recommended density is 3-7% for the major two or three keywords and 1-2% for minor keywords.

Try using the Checker Keyword Density in determining the density of keywords on your web site.

Although there are no strict rules, try to optimize for a reasonable number of keywords – between 5 and 10 is OK. If you try to optimize for a list of 300 words you’ll soon see that only you can not have a good density of keywords as well as some keywords appear in text as being an artificial, looking a likely intentional filling using keywords.

And what’s worse, there are severe penalties for such action (including prohibition of indexation in Search Engines).

The fact of trying to add a large number of keywords in an attempt to force some kind of indexing is considered an unethical practice Systems Search and good professionals who work with web optimization.

The keywords in Special Places
Keywords are very important as not only quantity but quality as well – egg the existence of keywords in the page title, headings, the first paragraphs – this type of strategy counts more than having many words Key in the body of the page. The reason is that the URL (and especially the domain name), file names and directory names, page title, and headings for the separate sections are more important than normal text content of a page and therefore, all equal if you have the same keyword density as its competitors but has keywords in URLs will boost your ranking significantly, especially with Yahoo.

Keywords in URLs and Filenames
The domain name and full URL of a site tell much about it. The presumption is that if your site is a subject or about dogs, you will have “dog” and “dogs”, or “puppy” as part of its domain name. For example, if your site is mainly about adopting dogs, it’s much better to name your web site as “adopt-cao.net” than “health-animal.org” for example, because in the first case you have two words important key in the URL, while the second one you have no more than one keyword, and lower potential.

When conducting research to get domain names, with relevance to keywords not greedy. Initially, if we observe from the point of view of SEO could be better to have 5 keywords in the URL, but imagine how it could be long and difficult to remember a long URL and with many words.

So, it is necessary to strike a balance between being able to associate keywords in the URL and usability with respect to the web site, where three or more words in the URL can be a little too much. You probably will not be able to have on their own with several interesting suggestions. Immediately, even if you can think of some good domain names, you will need to verify that they are not already registered.

Keywords in Page Titles
The page title is another special place because the content of <title> tag is usually displayed in most search engines (including Google). While it is not authorized by the HTML specification to write something on the label <title> (ie can be omitted but the title bar of the search engine will read “Untitled Document” or similar) for SEO purposes you may not want to leave the tag <title> without description, but instead you should describe the correct title for your page.

Unlike URLs, with the titles of pages you can use a more objective description of the title. If we follow the example of dog, Tag <title> the homepage for the web site http://adote-um-cao.net can include something like: <title> Adopt a Dog – Save a Life and Bring Joy to Your Home </ title>, <title> Everything You Need to Know About Adopting a Dog </ title> or even longer.
Keywords in Headings

Usually headers in separate paragraphs and sub-topics of a literary point of view may be pointless to have a header after every other paragraph, but from the standpoint of SEO is extremely good to have as many headers as possible on a page, especially if there keywords in them.

There is no technical limit of length for the content of the HTML “tags” <h1>, <h2>, <h3> … <hn> the use of tags but common sense says that headers too long may affect the readability of the page. Then, as with URLs, you need to be wise with the length headers. Another issue you need to consider is how the header appears. If you use ‘Heading’ 1 (<h1>) usually this is the larger font size and in this case it is recommendable to have less than 7-8 words in the header and the text should probably be spread among two or three lines, which would not be very good and is good and you can avoid it -

General rules
Make sure your main page is full of keywords. It has a higher chance of being indexed than your other pages, and it will be the only page indexed by some engines.

Some engines rank a page high if it has at least 100 words, so make that your minimum. Directories include pages based on the quality of their content, so make sure your pages aren’t simply lists of keywords.

Key concepts
When creating your pages’ content, keep the following four concepts in mind: Keyword prominence, proximity, density and frequency.

Keyword Prominence
The best place to place keywords in the text is at the top of each page, preferably the main page. The closer your keywords are to the start of the page or the start of a sentence, the better. This concept is known as “keyword prominence.” You’ll frequently see it used to describe search engines’ algorithms.

Some engines also say the bottom of the page should contain keywords as well.

Beware! Search engines view pages differently than people do. Here’s an example:

Keyword density as an optimization unit.

Keyword density is a correlation of quantity of all words on your page with quantity of keywords. Keyword density is usually expressed in percents. For instance if you have 100 words and seven of them are keywords – your page’s keyword density is 7%. Keyword density is always measured per-page, never per site, because search engines consider a page to be the smallest independent unit.

What keyword density is allowed by search engines?

All search engines have a lot of criteria to measure a web page. Keyword density is one of them and it is one of appreciable ones. Search engine algorithms are complicated mathematical measures and each search engine has it’s own – that is why allowed keyword density can vary for different search engines. If you are targeting one search engine – you can try to find out it’s allowed keyword density and keep it. If you target two or more – keep minimal keyword density allowed by one of them.
What are actually keywords and how search engines find out what are keywords on my page?

We know that keywords are search terms we seek, but a search engine doesn’t knows what keywords have you actually installed in your web page, unless you list them in META keywords tag (however, it is more like that the majority of search engines ignore this tag). So how do I count keyword density. Count the maximum repeating words! Even if your site is about apples, but there are more “garden” words – search engine will count maximal quantity of similar words. This means that you have a total of 100 words, 10 of which are “apple” and 30 of them are ��garden”, you can get penalized for �€œgarden” word. Note that articles, pronouns and other keyword-neutral words are not counted as keywords. The most convenient way to get full keyword analysis of your page is to use appropriate software. There are a lot of free and pay keyword analysis tools online.

There are another significant notion in counting keyword density of a page – keyword phrase. You know that some keywords consist of two words – product names, geographical names, etc. Search engine algorithm is also looking keyword phrases, which are defined by finding repeating keyword phrases. Clear? I hope so.

How do I count up right keyword density?

It is a unique way of research for each webmasters. Yes, there are some commonly known recommendations, but during last two years I���ve heard more than hundred numbers of “right” keyword density. Create a couple of page with different keyword density and optimize ‘em in the same way (this doesn’t means creating a couple of identical pages with different keyword density, because you will trigger duplicate content filter doing so) and see the results. Sometimes it takes many time to find out the right value. Some of my sites are under 10% limit, some have no more than 5% – you will find your best quantity soon, trust me. However, there are some variables which can influence allowed keyword density – position of keywords. I believe that keywords in H1 are considered heavy, just as keywords in links text, keywords in “bold” tag and those, which are placed close to the beginning of the document. That is why there is no definite quantity of keyword density.

1. Idea and planning
2. Choosing keywords
3. Writing texts for site
4. Stuffing text with keywords
5. Compose site and put it to web
6. Check site (includes checking of all levels of site – HTML coding, scripting, accessibility, site navigation, optimization, checking for broken links, grammar and spell check, keyword density check, etc.)

Writing texts for a site I don’t care keywords density and keywords during this first step, because it’s easier and quicker to write a text right from your head than to refer to keywords list each time you have to write them. After writing a text I insert keywords and keyword phrases. The third step is keyword density analysis performed with help of software. I usually keep keyword density under 5-10% depending on their similarity, position and frequency (as I have already mentioned in previous part of this article, “keyword frequency” is a term we use to describe intensity of keyword usage, e.g. how many times per day does this keyword being searched by surfers).

After installing keywords and checking keyword density I check the text once again reading it several times aloud to appraise sounding, ease of reading and simplicity of comprehension. Keeping keyword density under 5-10% is important because of two reasons – to avoid getting filtered for keyword overstuffing and for simplicity of perception. Some webmasters put keywords just where they want them to put or where keywords will give some meaning. Neglecting perception simplicity and ease of reading you scare of potential buyers! Vary keywords, find synonyms, check your text ten times before posting it to your website. So the rules are:

1. Keep your texts comprehensive and easy-to-read.
2. Don’t compose keyword phrases to the detriment of understanding.
3. Don’t overstuff your text with keywords.
4. Keep keywords in logically correct phrases and sentences.

Let’s take a closer overview of the fifth point. You can often find pages containing lines of meaningless keywords anywhere on the page, but not in text. This is the way how webmasters who don’t want to spend some time inserting these keywords in text do. It is a very rough mistake, because Google is actively using linguistic analysis filters. As far as they find such meaningless line(s) of keywords, page gets filtered out. Moreover, it corrupts appearance of page and scares customers. Keep your whole site cute if you want to do good marketing.

Understand what actually keyword stuffing is.

We have already talked about average allowed percentage of keyword density, but it is important that you understand that this quantity means equal distribution of keywords through all parts of your page. If you put all your keywords in one single place, or nearly this can also neglect all your attempts of creating a good page. For instance (already mentioned), you shouldn’t put more than three keywords in title, more than 3 keywords in META description, and accurately distribute the rest of keywords along your text.

Summary.

Everything mentioned in this article is my own experience for as long as 5 years dealing with SEO. I just want you to understand importance of linguistic approach to site building. I have even hired a linguist to check, correct texts and give me tips in his field. I’ve hired him, because I’m not a native speaker and I doubt my grammar and spelling – you can see this from this article (it hasn’t been checked by my assistant).I must say I’m very satisfied with results – writing good texts, attractive descriptions and reviews I have increased my sales up to 20-25%. That is why I give much importance to the language.
