If I spend more on Google ads will I definitely get more leads?
Spending a certain amount doesn't guarantee you a certain amount of conversions. There are other variables at play here, including the quality of your ad and the skill of your sales team. Keep in mind that Google Ads just brings the consumer to your website. It's up to you to make sure that your ad is bringing in good, qualified leads and that your sales team is following up promptly and converting them when they reach you.
