By relying so much on factors such as keyword density which were exclusively within a webmaster's control, early search engines suffered from abuse and ranking manipulation. To provide better results to their users, search engines had to adapt to ensure their results pages showed the most relevant search results, rather than unrelated pages stuffed with numerous keywords by unscrupulous webmasters. This meant moving away from heavy reliance on term density to a more holistic process for scoring semantic signals. Since the success and popularity of a search engine is determined by its ability to produce the most relevant results to any given search, poor quality or irrelevant search results could lead users to find other search sources. Search engines responded by developing more complex ranking algorithms, taking into account additional factors that were more difficult for webmasters to manipulate. In 2005, an annual conference, AIRWeb, Adversarial Information Retrieval on the Web was created to bring together practitioners and researchers concerned with search engine optimization and related topics.
In order to quickly identify the correct content and websites that will meet their needs almost all users will use a search engine such as Google. Typing a query into a search engine will generate a set of results that are a combination of paid and organic search listings. The user can then choose the most relevant link from these results or search again if the results are not helpful.
While there isn’t much you can do about how long your website has been around, it’s important to note this factor if you ever want a new website for your business. It’s more beneficial to keep an old domain and redesign the layout than it is to start from scratch. A page’s authority isn’t always the same as the whole domain’s authority, but they’re determined in the same way. New web pages on an old domain will still have the domain authority to back it up, but their page authority will start out at 1.
Everyone wants to rank for those broad two or three word key phrases because they tend to have high search volumes. The problem with these broad key phrases is they are highly competitive. So competitive that you may not stand a chance of ranking for them unless you devote months of your time to it. Instead of spending your time going after something that may not even be attainable, go after the low-hanging fruit of long-tail key phrases.
Well, yes and no. Sure, you can get hit with an algorithm change or penalty that destroys all your traffic. However, if you have good people who know what they are doing, this is not likely to happen, and if it does, it is easy (in most cases) to get your visits back. Panda and Penguin are another story, but if you get hit by those it is typically not accidental.
