This news has been issued in the Search Engine Journal by Roger Montti. According to the Montti, google has not told exactly how much amount of ads credit will be transferred to the ads account of small businesses.
Note that, this offer is only for those small businesses who were already running google ads from the past year to promote their products or services.
Hence, this offer is not eligible for small businesses who will open new google ads account.
Google has taken this step, to help out small businesses that are adversely affected by the corona virus pandemic.
I strongly believe that a small business needs to step up its business strategy and increase its investment in digital marketing to sustain their business in the pandemic.
