BRUSSELS, Dec 11 (Reuters) - More than 20 price

comparison websites across Europe on Wednesday criticised

Google's proposed changes to its search results, saying they

still fail to comply with EU tech rules and urged regulators to

impose charges against the Alphabet unit.

Google has been discussing with the comparison sites,

hotels, airlines, restaurants and retailers for more than a year

now on how to comply with the Digital Markets Act (DMA), which

prohibits it from favouring its products and services on its

platform.

Last month, it announced its latest proposal, which includes

expanded and equally formatted units to allow users to choose

between comparison sites and supplier websites.

It may also bring back its old "ten blue links" format from

years ago as an alternative if it can't agree with its rivals.

This format is now being tested in Germany, Belgium and Estonia.

The price comparison websites, which include Germany's

Idealo and billiger.de, France's Le Guide, PriceRunner, Kelkoo

and kieskeurig.nl and trovaprezzi.it, said Google has not

listened to their feedback.

"Google has simply, repeatedly, ignored this feedback, and

instead continued to iterate on the same non-compliant solution

for months," they said in an open letter.

"If Google has not taken feedback into account after more

than 100 events, it can only mean one thing: Google is wilfully

not complying with the DMA."

When asked for comment, Google referred to its Nov. 26 blog

post where it pointed to the many changes it had made over the

past year to comply with the DMA and find a solution.

The websites called on the European Commission to act

against Google.

"The Commission has opened proceedings against Google for

non-compliance. It must proceed with such proceedings, issue

preliminary findings, and impose fines on Google, including

periodic penalty payments, to force Google to finally listen and

comply," they said.
