They need 3 devices with 3 starting price points:
$400, $700 and $1000
Make sure they all have a similar design focus and direction behind them. You can add a bigger screen and an extra camera to the $1000 one, and maybe a bit bigger of a battery. Have the $700 be the best of both worlds. $400 could have a similar screen and SoC, but have a sturdy, polymer body.
Also, make it state of the art for when the phone comes out. The thing is, Samsung releases their new phones with the latest Snapdragon SoC around March/April, but it takes Google until Oct/Nov for them to pick up on this kind of power. Not only that, Google is usually behind other Android providers in terms of RAM offered, storage options and colors. Outside of a couple more features from one Pixel to the next and software updates being supported, they do nothing to truly show if and why you should upgrade to their new phones.
On top of this, they basically don't market their fucking hardware division much at all. The most I see Pixel or anything of the sort are with Verizon commercials.
The Pixel line reminds me of the several iterations and simultaneous messaging apps that Google creates. They may do something, but their is a feel of confusion and a lack of marketing and explanation basically harms them in the end. Google bought HTC, a hardware company, and has barely, if at all, put them to use. At this point, I kind of hope Google skips the Pixel 5 and does something entirely new to go against Samsung or something in Spring 2021.
So, Google, this is what could really help you:
1. Three devices with 3 different starting price points that allow many more people to jump to your products.
2. Actually market your fucking phone and stop making phone carrier (like Verizon) timed exclusive deals.
3. Release your devices earlier in the year, especially if they are meant to go up against something like the Galaxy phones and OnePlus devices. Being late to the party basically makes people who already have a Galaxy or OnePlus device go, "Why should I get basically the same phone again 6 months after I bought this one?"
4. Along with the products, please provide a much wider array of storage limits and colors. If need be, provide more RAM for the more expensive phones, but give these phones more RAM (8GB for the $400, 12GB for $700 and 16GB for $1000, something like that).
5. Please, for the love of fuck, keep front facing speakers.
End rant.
PS - I love my Pixel 3.
