Google has denied that it has made significant modifications to the 'farmer' update it applied to its search engine marketing algorithms last week.
The firm told Search Engine Land's Danny Sullivan that it had not made any large-scale alterations to the code in response to claims that legitimate websites had been caught up in its attempt to filter out spam.
It also denied there had been any manual adjustments, following the case of Cult of Mac, which originally disappeared from the listing in the wake of the update, only to be restored a few days later.
However, the company did encourage those who believe they have been unfairly demoted in its search results to file a report though its Webmaster forum.
"Sites that believe they have been adversely impacted by the change should be sure to extensively evaluate their site quality. In particular, it's important to note that low quality pages on one part of a site can impact the overall ranking of that site," Google added in a statement.
According to the company, the changes to the algorithm, which are intended to reduce low-quality content in search results, will affect around 12 per cent of queries performed on the site.
