For SEO, the content should be strictly focused on the topic and centered on the relevant Keywords. Search engines crawl the relevancy of the page based on the keywords. Do not assume that they just see the keywords alone. They are smart enough to evaluate the significance of the keyword with regard to the entire content. Spamming with keywords will never work, in fact it will have a negative impact on the content, ie you will no longer be noticed by search engines. It is crucial to research and be creative to find and use keywords especially in the online world because it dictate whether you attract browsers or buyers, information seekers or product and service seekers, and finally, keywords even help to determine how many visitors you receive from search engines.
Before writing the content a careful analysis of the competitor with respect to the content and keywords is vital. Also there is no point in writing a large content with unnecessary explanation. Users will get attracted to quality content and also in the very first paragraph itself you need to provide the summary of the article by following the journalistic norm ie, the content should be in an inverted pyramid style including 5 W’s(WHAT , WHO, WHY WHICH, WHEN, WHERE and 1H (HOW).
Title is the first thing that a potential visitor will find in search results. Keywords should begin with the title in order to woo the search engine and also the users. Also important is the Meta description which induces whether or not you get the click and it should be limited to 165 characters so that the full description will be visible in search results. A keyword density more than 5.5% will be considered as keyword stuffing, and certainly irritates Google. Keywords alone cannot take your site on the top slot on a search result page but using the right keywords plays a great role in getting search engine traffic.
Your site can be accessed only through the relevant keywords and without them it is invisible to everyone whatsoever, useful and informative they may be. A professional copywriter will always learn the competition for the product or service and hence use appropriate keywords at the right places with accurate headings. The keywords should be proportionate and equally disseminated throughout the content.
