I am wondering if it is worth hiring someone to look over it for like 1-2 hours just to make sure a didn't leave out something that will crush the whole thing.
There are a number of elements that determine whether or not it's worthwhile to hire someone to examine your Google Ads campaign for one to two hours, but here's my analysis based on the information you've provided:
Motives for thinking about hiring someone
Limited experience: If you're not familiar with Google AdWords or haven't managed sophisticated campaigns before, getting a fast evaluation from a qualified expert will help you spot potential problems and areas that need work.
Complexity of the campaign: Having a professional review your setup helps guarantee that everything is adjusted for effective performance, especially if your campaign includes several ad groups, targeting options, and bidding techniques.
Peace of mind: If you've committed a lot of time and money to your campaign, hiring someone for a one-time assessment can provide important assurance that it's headed in the correct direction.
Considerations prior to hiring:
How confident are you? A review may not be required if you are satisfied with the way your campaign is set up and have done extensive study on best practices.
Budget: One-time sessions can be pricey, so consider your financial limits as well as the possible benefits before making a decision.
Here is a suggestion:
Rather than a broad evaluation lasting one to two hours, you may tailor the consultation to address particular areas that raise questions or concerns for you. This might be your landing page optimization, ad copy, bidding strategy, or targeting strategy. You can optimize the value of your session and obtain more focused input by limiting the scope.
The choice of whether or not to hire someone is ultimately yours. Weigh the aforementioned variables while taking your budget and unique needs into account. Recall that, in the long term, investing even a small amount on professional guidance may save you problems, money, and time.
