Can someone please assess my Rover profile?

Welcome to Rover!
I pretty much second everything Walt said.
First thing's first, you have to get yourself higher in the search rankings (you were on page 15 when I searched for you, but maybe that's just me). You can do this a number of ways - confirm your availability all the time. Rover will ask you when you log in if you're available for a certain period of time. Click "confirm availability," and you're more likely to come up higher in search results. Respond to messages super fast (within an hour if you can). Archive messages quickly - messages in your "pending" folder mark you as unavailable for the requested dates, even though you're not booked. And you won't show up in search results for those dates. Make sure you choose a non-detrimental reason for archiving ("owner's plans changed" or "duplicate message"), otherwise I think it reflects poorly on you. Also, get as many badges as you possibly can. Take a pet first aid/CPR class so you can get that badge. I am pretty strapped for cash, but I would still pay a little extra for a pet sitter with official pet first aid/CPR training, and if two sitters were the same price, I'd go for the CPR certified one, hands down. Just a thought. Once you sit for someone, give 150% (especially when you're new) to make sure you get that 5-star review. Send pictures and updates every day, and know that if you don't send pictures during a stay, that's reflected on your profile afterwards (I'm not sure if it affects your search rankings).
Change your primary photo to a crystal clear headshot where you look your absolute best (the happiest, most professional version of yourself). That's the picture that shows in the search, which is why I suggest a close-up shot instead of a full body shot. Bonus if you have a great dog kissies picture.
Try to get a headline that either establishes that you are more professional than other sitters or you have something they don't. Don't look at mine. It's a work in progress, lol. My last one was "Jean & Ray's Canine Cottage," (we had a little house in the woods), and I had a facebook page that matched it in case someone googled me - I think appearing on multiple sites gives you more credibility, imho. The name and the facebook page were just to make us sound more like a business, instead of just some stranger on a website people just signed up on.
In a similar vein, try to make your profile sound more professional. You have a great start. Definitely drop the LOL and try to have a few short paragraphs where each paragraph has a theme (services you provide, history about your dog experience, what you most love about dog sitting, etc.) - think "short essay". Also, read through your profile a ... (more)
