I Need Some Advice Before I Start Using Google Ads

Focus on conversion tracking first, then work on targeting and keywords once you know your data is accurate.

The best advice for beginners: build an extensive negative keyword list before spending your first dollar. Don't jump straight into Broad Match or automated Performance Max campaigns; Google will burn your budget on irrelevant search terms. Start with Exact and Phrase match, collect conversion data for at least 2-3 weeks, and only then let the smart bidding algorithms take over.

You should start with the basics and understand your keywords, targeting, and conversion tracking first if once tracking is set up correctly then focus on improving your ads and budget based on the data.

I think you should start with the basics like conversion tracking and keyword targeting and once the data is clear it becomes easier to optimize the campaign.
