Whenever setting up an Adwords campaign, I use the following method:
- Ad Targeting - be extremely granular, research where your target market is by geographical location, what device they would be using/or your website is optimised for, the time of day and most importantly your keywords. This is by far the most important part of setting up your campaign, make sure you're not targeting too broad keywords, either go for phrase match type or exact match type. This will lower your click throughs but most likely increase your conversions and not demolish your budget.
- Ad copy - make compelling ads, take time to write clear, concise and clickable copy, if using image ads, hire an amazing HTML5 banner designer to create you some interactive banners. Get all the popular sizes, 300x250, 728x90, 468x60 and 160x600.
- Optimize Landing Pages - don't send users to your home page. 99% of the time people clicking adverts want to see a quick overview of your company or what you have to offer. if they like the look of you they will click through to your home page and check you out further. Make sure your landing pages are mobile friendly, lightweight and easy on the eye.
- Monitor the campaign - After launch watch things carefully, monitor your ad spend, remove keywords that are unrelated, tweak, tweak, tweak until perfect.
If all else fails, hire a reputable PPC manager to do things for you (but they are hard to come by in my experience).
I could go in to this further but my fingers are beginning to ache... Other than using Adwords, I'd suggest also looking at Bing (cheaper), Coin Traffic and even approaching website owners directly to see if you can purchase space on their site.
You can now officially scrap this comment, as Google has said they will ban crypto ads in June this year, maybe time to start looking at Bing, unless they follow suit, which could be likely. I guess it depends how much they moola!
