Search Engine Optimization (SEO) is one of those endeavors that is "10% inspiration and 90% perspiration". In other words, it involves a lot more hard work than rocket science. Achieving a high search engine ranking is a "simple" matter of getting quality websites that are related to yours, or in the same industry to link to yours, and even more importantly, putting a lot of original content on your site. The content should contain the right keywords for searches to find your website, and be readable by the search engine spiders. The free online search engine optimization tools below will help with these tasks.
This tool checks the search result pages (SERP) of the Google, Yahoo, and MSN search engines to show the ranking of your web site for a particular keyword or key phrase.
You can check the Google PageRank for a website using this tool. Enter a URL or a list of URLs and it will return the PageRank value for each one.
Google PageRank is a general measure of a website's popularity. It is primarily based on link popularity. Websites with a high PageRank value will tend to have more traffic and higher rankings in search engines (although this depends on many other factors also).
Enter a valid URL, and this tool will query all the major search engines (Google, Yahoo, MSN, and Teoma) and then return the number of websites that link to that URL. The numbers vary greatly from search engine to search engine because the figures shown represent the number of inbound links that are known to that search engine (which will vary based on the size of their database). Most of the search engines (Google especially) also apply various filters to the inbound links, therefore, some inbound links may not be counted.
A lot of content and links displayed on a web page are visible to the viewer but may not be visible to the search engine spiders. Such content includes Flash based content, content generated through JavaScript, or Java, content displayed as images, and other. Basically anything rendered on the client side such as by Java or Javascript may not visible to search engines.
Also, dynamically generated content may not be visible. This tool simulates a search engine spider by displaying the contents of a web page in exactly the way the spider would see it.
The Keyword Suggestion tool for Google will help you choose relevant and popular terms related to your selected key term. Enter a keyword or key phrase and this tool will return popular and terms used by websites in the same industry.
The relevancy of a key term is determined by counting the number of times a given term occurs in searches. Some terms may have a higher relevance than the term you entered because they appear more often in Google searches related to your term than your input term does. Depending on Internet traffic as well as the keyword/phrase, the query may take anywhere from 10 to 30 seconds to complete.
The Overture keyword suggestion tool will help you choose relevant and popular terms related to your selected keyword or key phrase. Enter a key term, and this tool will query information from the Overture database of searched terms and return a list of keyword suggestions, as well as the number of times that term has been searched for in the last month.
