Marketing/PR Assistance for Swimwear Brand

I have a swimwear company and have previously received the majority of my traffic from SEO. I rank very highly for a lot of keywords. However as we are now approaching Summer I really need some assistance with Marketing/PR to get more traffic to my site and reach new customers. My traffic has slowed down recently and I need to increase this again.

I gift influencers on social media to increase brand exposure but I would like to build on this and other forms of Marketing/PR. I would like to work with someone who has experience in this field and can help assist me reach a bigger audience and drive sales over the next few months. Possible ideas include facebook ads (I am trying this currently but struggle to know if I am optimising it currently including Shoelace), google ads and other forms of PR plus a more sophisticated gifting/paid instagram post approach with influencers/celebrities
