Early versions of search algorithms relied on webmaster-provided information such as the keyword meta tag or index files in engines like ALIWEB. Meta tags provide a guide to each page's content. Using metadata to index pages was found to be less than reliable, however, because the webmaster's choice of keywords in the meta tag could potentially be an inaccurate representation of the site's actual content. Inaccurate, incomplete, and inconsistent data in meta tags could and did cause pages to rank for irrelevant searches.[10][dubious – discuss] Web content providers also manipulated some attributes within the HTML source of a page in an attempt to rank well in search engines.[11] By 1997, search engine designers recognized that webmasters were making efforts to rank well in their search engine, and that some webmasters were even manipulating their rankings in search results by stuffing pages with excessive or irrelevant keywords. Early search engines, such as Altavista and Infoseek, adjusted their algorithms to prevent webmasters from manipulating rankings.[12]
Keyword research tells you what topics people care about and, assuming you use the right SEO tool, how popular those topics actually are among your audience. The operative term here is topics -- by researching keywords that are getting a high volume of searches per month, you can identify and sort your content into topics that you want to create content on. Then, you can use these topics to dictate which keywords you look for and target.
In December 2009, Google announced it would be using the web search history of all its users in order to populate search results.[33] On June 8, 2010 a new web indexing system called Google Caffeine was announced. Designed to allow users to find news results, forum posts and other content much sooner after publishing than before, Google caffeine was a change to the way Google updated its index in order to make things show up quicker on Google than before. According to Carrie Grimes, the software engineer who announced Caffeine for Google, "Caffeine provides 50 percent fresher results for web searches than our last index..."[34] Google Instant, real-time-search, was introduced in late 2010 in an attempt to make search results more timely and relevant. Historically site administrators have spent months or even years optimizing a website to increase search rankings. With the growth in popularity of social media sites and blogs the leading engines made changes to their algorithms to allow fresh content to rank quickly within the search results.[35]
“Not only is the report beautiful, but it shows all of the pertinent information required for a SEO site audit, and then some. This report pointed out some metrics and server vulnerabilities that other audit companies (WooRank, SEO Powersuite, iBusines Promoter) just did not mention. The web interface for the reporting is great, simple and easy to use. Reports are saved in the portal for later use, which is also great. Overall, I think this product looks great and I plan to use it as the main bulk of my SEO auditing as a SEO consultant.”

Google will INDEX perhaps 1000s of characters in a title… but I don’t think anyone knows exactly how many characters or words Google will count AS a TITLE TAG when determining RELEVANCE OF A DOCUMENT for ranking purposes. It is a very hard thing to try to isolate accurately with all the testing and obfuscation Google uses to hide it’s ‘secret sauce’. I have had ranking success with longer titles – much longer titles. Google certainly reads ALL the words in your page title (unless you are spamming it silly, of course).
And you’ve got to diversify. Here’s a tongue-twister that’s absolutely true: diversity is a key word in the keyword world. You’re not going to stand out if you find yourself using all of the same keywords as your competitors. Not only should you try new keyword search tools and keep track of the results, but you should feel free to experiment based on your own research – who else uses your keywords? And how do you make yourself stand out? By providing great content that truly answers the questions your prospective customers are asking with their keyword searches.
