What other mechanisms are possible to market a stakepool?
Here is a quick brainstorm.
You have to know your target group or at least try to reach your target group.
There are users who try to
If you try to reach users who want to maximize their staking return, your listed incentives are good. However, for small pools it will be challenging to be seen, as there are many large pools who already offer zero margin while providing a high block-minting probability. Personally, I believe that the differences between "normal" and "min-maxed" pools are too small to matter. All you do is try to take advantage of filters and search algorithms on certain pool comparison websites.
If you try to reach users who want to support the network by supporting smaller pools and increase decentralization, you just have to "be known". Overall I think that it is difficult to target this group of users specifically. Just try to be an option.
Your best bet is to have something that makes you special. If your pool supports a certain project, you could advertise your pool in this community. If you have a social media following, you can advertise there. You mentioned starting a podcast. To advertise your pool in your podcast, you have to advertise your podcast first. Some users try to support local pools specifically. Use this as an advantage to advertise your pool in a local Cardano community, for example a language specific Cardano subreddit.
The overall best way to get pledges is to become known (duh!). Participate in Cardano communities using a name like "XYZ Pool" and provide good content. Maybe you can use your answers to subtly drop the info that you operate a pool, for example when people ask how much it costs to operate a pool, or when they ask for certain pools in particular. Small events like giveaways are also a great opportunity for acceptable advertisement, as long you select an acceptable platform.
