New rules have come into effect across the EU that will provide greater transparency when buying goods online.
The new measures will also ensure compensation for victims of unfair commercial practices.
Among the new changes will be measures to prevent a person being commissioned to submit fake reviews of products bought online.
Tim Hayes from the European Commission office in Dublin says the rules around reviews are changing too.
"We have changed the rules in a number of specific areas for consumers," he outlined.
"One of which is the transparency of online market places so you know who exactly is selling to you if it is a business or a private individual.
"We have also introduced transparency (in) customer reviews so you can no longer introduce a 'fake' review about a product," he added.
