come here to increase my knowledge
Sure. I will increase your knowledge. The sun is shining more on Google Ads.
So, instead of presenting old wine in a new bottle, why not present new wine in a new bottle ?
In other words, why not also become a "Google Ads expert" ? That way, you can easily make your hay while the sun is still shining. So, instead of "I am a link building expert. We have worked with many clients", if you make it "I am a Google Ads expert. We have worked with many clients", it will make lots of fish to come into your net and many of such fish will be fat and juicy, so your leverage would be more, as there are always suckers born every minute, don't worry, you will achieve your mission very easily by being a "Google Ads expert".
Wish you success ... Cheers !!!
