Changes with Google’s algorithm began last November 2003 with the Florida update, which is now considered as the most historic in the webmaster community. The Austin, Brady, Bourbon, and Jagger updates followed suit, and from then on, Google updated appeared monthly and now, it is carried over every three months.

With so many servers, it has been found that various results appear on the servings at any time within the quarter. BigDaddy, the most recent update made by Google, has its share of the blame. Thought of to be a 64-bit architecture, this update is considered to be a part of the algorithm that caused most pages to drop to the 100^th place or even worse, to the supplemental index.

BigDaddy’s algorithm falls on the four categoirs: canonical issues, duplicate contents, Sandbox, and supplemental page.

Canonical issues

These take place when the search engine thinks www.yourdomain.com, yourdomain.com, and yourdomain.com/index.html as not the same web sites. When this happens, the site is labeled to have duplicate content and it ends up being penalized. This is one issue that major search engines like Google is easy to deal with, though Google’s inability to address this issue hurts its reputation as being the world’s largest search engine.

Sandbox

Google implements time penalty on new links and sites because of it believes it is impossible to create 100,000 pages at an instant. Thus, some websites are considered sandbox for a time before they are eventually indexed in Google. With this, speculations arouse that there are only a few sets of competitive keywords are sandboxed. Today, the presence of sandbox is widely debated, though Google fails to confirm this.

Duplicate content

Duplicate contents stem from Black hat SEOs who duplicate contents of a website and considered it their own, thus, they are able to produce thousands of web pages at an instant.

Supplemental page

Supplemental page is also dubbed supplemental hell, according to web masters since this issue has been lurking for a long time now, only to be broken loose after a major shakeup in the web community last February.

As an SEO firm, we strive hard to avoid this problem and to continue coming up with ideal strategies fit for the standard of Google. It is being hoped that by next year, Google Caffeine would enable us to have strategies that will further improve the use of ethical SEO techniques.

As for the certain impact on SEO, you should consider focusing on the enhanced weight on domain authority because older sites are more prominent compared to the newer ones with the authoritative tag type pages, such as Technicolorati tag pages + Facebook tag pages, which allows the site to have more weight on the exact match domain names. Consideration should also be due with rich keyword domains improve slight bump and offer better understanding on the keywords.
