Those don't seem like examples anti-competitive practices in the search engine market. In fact they don't seem like anti-competitive practices at all. This first supposes that there's a meaningful "market" of "ads on Google", which is an unreasonably narrow scope of products to try to define as a market, and the second seems like a straightforward function of a search engine. If Google Search did something like refuse to return results if you searched for "Bing" or "Yandex", that would be an example of an anti-competitive practice in the search engine market, but when I test those searches the first results are the Bing and Yandex homepages.
