Google Sandbox
In March 2004, Google allegedly introduced the Sandbox effect in an effort to prevent spam websites achieving a high ranking soon after launch.
The Google Sandbox filter is like a probationary period for a website which typically lasts up to 12 months. During this time, affected websites may perform badly in the Google organic search listings against competitive terms. During the period of the Google Sandbox, website trust metrics are assessed which then play a considerable part in determining the future ranking of the site after its release from the Sandbox.
One theory concerning the Google Sandbox is that it effectively extends the normal backlink ageing process, meaning that acquired backlinks offer reduced benefit for an extended period of time until the trustworthiness of any new website is established by Google.
More recently, some SEO experts dispute the existence of the Sandbox, preferring the theory that a new website has poor initial ranking purely due to a lack of trusted inbound links.
The effect of the Sandbox filter is to reduce the ranking of some new web domains, making it very difficult for them to compete in the Google search engine results (SERPS) even for slightly competitive keywords for periods of up to 12 months (maximum).
Whilst affected by the Google Sandbox effect, it may be possible for a website to rank for non competitive terms, so long tail keyword selection is advisable when SEO copywriting for new websites. Importantly, acquiring more "trusted backlinks" from established hub sites can help a new website escape the effects of the Sandbox filter earlier.
What Triggers the Sandbox Filter?
There is strong evidence that the Google Sandbox filter is triggered by unnatural link building activities and website over optimisation soon after launch or first Google indexing. Interestingly, the Sandbox seems to only affect English language websites and has never been known to effect .gov, .edu domains.
Excessive reciprocal link building and acquiring too many inbound links at the same time in an attempt to artificially raise the ranking of newly launched sites is the most common cause of triggering the Sandbox. Since new web domains often start with few links, it is easy for Google to spot irregularities in backlink acquisition rates and repetitive anchor text.
To try to avoid the Google Sandbox altogether, we recommend that new websites avoid too much reciprocal link building and instead concentrate on acquiring one way links from high Page Rank web directories, article submission sites and most importantly for Google ranking, authority hub sites of a similar theme. It is also important to avoid site wide links pointing to your site as these are often used by spammers and can have a negative ranking effect, since many site-wides are bought links.
Testing For The Google Sandbox
Websites which are heavily affected by the Google sandbox tend to demonstrate a large differential between their ranking for an allinanchor:<keyword> search or allintext:<keyword> search and the same keyword term in Google's regular organic SERPS. So, to test for the Sandbox effect, choose an appropriate keyword and check the ranking difference between allinanchor and the regular Google organic search results.
Websites affected by the Google Sandbox effect may rank well in Yahoo! and MSN as these search engines will give benefit for new backlinks much sooner. They're also much less picky about link quality and relevance than Google, so pretty much any inbound link will help Yahoo! and MSN website ranking.
In contrast, many links are discounted by Google from the outset due to reciprocation, lack of trust (of link source) or lack of thematic relevance. So, all of this taken into consideration, it is common for a Google Sandboxed website to rank between 300 - 500 for a certain keyword, whilst ranking top 10 in Yahoo! and MSN for the same term!
During the sandboxed period, Google scrutiny is focussed on link acquisition trends and website quality metrics, such as:-
- Backlink acquisition rate - the rate of acquiring links to your website from other sites / domains
- Quantity of backlinks - how many other websites on the World Wide Web link to your website
- Quality of backlinks - the number of low quality reciprocal links versus high quality one way links from authority sites and reputable directories like DMOZ.org
- Outbound linking from your website to bad neighbourhoods or link farms
- Significant levels of reciprocal linking with poor quality websites and websites of dissimilar, irrelevant theme
- Backlink anchor text variance data is assessed. Adding too many backlinks with the same anchor text can hurt Google ranking and trigger the Sandbox filter, particularly where webmaster collusion is obvious, such as where the links are all reciprocated. We recommend that you check backlink anchor text for variance using the excellent new SEO tool at http://www.webuildpages.com/neat-o/. SEOMoz have a similar tool available to their preimum members.
- Quality of website content - checking for spam, keyword stuffing or excessive keyword repetition
The greater Google trust your website acquires, the faster you will escape the Sandbox filter and see improved keyword ranking. Websites are typically released from the Sandbox en masse when Google is satisfied that they reasonably adhere to their quality guidelines and have built up sufficient trust.
There is some evidence that the Sandbox can be extended for websites which adopt poor SEO techniques and badly managed link building campaigns soon after launch. An over reliance on building large numbers of reciprocal links during first 12 months after website launch is equally ill advised, often leading to a massive drop in Google ranking.
Tips to Escape the Sandbox Early
Escaping the Google Sandbox early seems to be possible, and there is reasonable catalogued evidence that early release from the Google Sandbox filter can occur if sufficient quality one way links are acquired from authority websites - these are hub sites which are leaders in their particular field. This goes some way to explaining why websites relating (for example) to new movie releases never suffer the effects of the Google Sandbox filter as they acquire many quality links from the outset and don't need to adopt damaging artificial SEO practices to boost website ranking!
Rather than focussing too much on SEO for a new website, we strongly recommend that your initial efforts concentrate on building up your website as a unique information source with informative articles and topical news. This will really help your website to acquire a natural spread of one way links pointing to an important cross section of your internal pages as well as your homepage, helping to release you from the Google Sandbox.
Use all aspects of search engine optimization in moderation whilst a new website establishes itself. Keyword stuffed titles, Meta tags and excessive repetitive keyword usage in website content should be avoided as this can actively reduce the Google ranking of new domains, through triggering spam filters. When a website is new the threshold for spam filtering may be somewhat lower. KSL Consulting have noticed web pages with natural language text and inherently low keyword density can outperform keyword stuffed pages, at least in some part because they attract more natural links.
Since a Google Sandboxed website will have poor ranking against competitive keywords, it makes sense to optimise for less popular long tail keywords whilst in the Sandbox. For advice on choosing the best long tail keyword phrases using free SEO tools, read our long tail theory advice page.
