Google sandbox

What does the sandbox theory claim?

According to reports, the theory dates back to around 2004. Site owners noticed that new domains ranked poorly for weeks or months despite solid SEO work, and explained it with a probation period. The durations quoted online range from a few weeks to a year, and none of them has a primary source.

Google has pushed back on the idea. In 2018, John Mueller said Google does not have a traditional sandbox but has a number of algorithms that might look similar, as quoted by Ahrefs. Google’s overview of its ranking systems lists no filter for young domains.

Why do new sites rank slowly anyway?

Several ordinary causes can produce the same pattern:

• Google first has to find, crawl and index the new pages.
• A new domain has few backlinks, while established competitors have many.
• Competitive queries already have many strong results.

The SEO Starter Guide adds that changes to a site can take effect within a few hours or take several months.

Not the Privacy Sandbox

The Privacy Sandbox is a set of Google technologies for advertising without third-party identifiers, mainly in Chrome. It has nothing to do with search rankings. Search results for the term often mix both topics.

Example

A new site is indexed within a week and ranks first for its brand name. For product terms it appears on page four after three months. Whether a sandbox, missing links or strong competition is the cause cannot be decided from the outside.

FAQ

Is the Google sandbox real? Google has not documented it. Slow starts for new domains are common, but a dedicated filter is not proven.

How long does it last? No reliable figure exists. Numbers online are experience values from individual SEOs.
