Its not even about the bite being good, just that some shore spots are too weed choked to fish in summer, and covered in ice in winter, LOL.
Technique? Same tech applies to shore as in a boat. Most boaters make the same mistake shore bound anglers do, just in a mirror image. Don't just chuck out ion the open water because you can. Sell the bait off as a vulnerable, easy to get meal. Know where the best ambush points are, the routes the bait use to move, and what's going on.
Example: Its early summer, and I'm froggin' my nooner pond. I'm seeing some blowups behind my frog, in open water. Weird, looks like they're missing. Then I see it happen in close. A blue gill that was following the frog's skirt legs just got munched..... Off to the truck for swimbait rod and a Hard Gill floater, and toss on open areas near weeds. Catch a few nice bass on a day where nothing was going on with the frog.
