Whether auto top up or manual top up, auto bidding or manual bidding it makes no difference kung ang products niyo same brand or products ng kapwa seller niyo - price war kayo pag ganyan (just think of it, sampu kayo o bente same products, same brands, lahat kayo naka sponsored discov or affiliate, naka fsm, vouchers, lahat na, sa pricing kayo magkakatalo at kung same price, sa reviews naman or customer service or outside platform marketing. Auto bidding - malaki cpc pero mas mataas chance ng traffic, pag manual bidding yes pwede mo ibaba cpc mo pero talo ka sa visibility kasi bidding yan. Mga best advice, increase variety - more different products or brands the better, be an exclusive distributor of a certain brand or product (plus points if you're a lazmall seller), make your own products/own brand, find your niche, then saka mag focus sa sponsored solutions and all other seller tools na meron.
