What's your product tagline?

I went to your FAQ and I found something great - "send mail merge right from your Gmail inbox", I would add something that will set it apart like "The fastest way to send personalized mail merge email from Gmail", or something along that line. Hope this helps :)

It blew my mind, seriously, loved it :)

Straightforward, but requires a bit of work. Help is the pain you solve, best is a matter of taste. I would try to find something that sets you apart, there's a lot of competition in your vertical, and having a killer magnetic slogan matters. Try something along the lines of "Beuty Product Search Engine", or something else that stands out, and A/B it of course. Hope this helps :)

Straightforward, but requires a bit of work. I would A/B test it against "Know what's happening on your website at all times". Although the "website is down, or malfunctioning" is pretty self-explanatory, it's basically "almost the same thing" It's not, but, I think you can find something better, hope this helps :)

I understand from your slogan that it's an onboarding product, but I don't understand how it's different, what specific pain it solves, you might want to try and A/B it against "We onboard customers successfully with X", hope this helps :)

I didn't understand what your product does from the slogan, I had to log into your website to understand what you do, I'd A/B it with something more explanatory, hope this helps :)

It might be a bit long, try to A/B it with, "Design logos with AI", or something along that line. Not that your slogan is a problem, just shorter.

Straightforward, it's a winner :)

Loved "Drag and drop your video to see your GPS track" :D It's a winner.

The PayPal, PYPL and Pydist game is tricky, to avoid misunderstanding, try not to focus on the negative of your competitor, i.e. privacy. Instead, focus on the pain you solve. Something along the line of "Mirror PyPl & Keep your python packages private" , or something along that line.

I would play around with Chat-style Form, especially since you're addressing a co-coding audience. Maybe something along the lines of "Create Chat Forms (Hybrids?), Without Coding Skills (try to avoid the word "no" in a slogan).

Is time a pain your users have? I dunno, I would try to A/B test against "Track your gym workout, Progress More". Hope this helps :)

Straightforward, loved it. I would A/B test Curated with either "Resource" or "Collection" etc. Hope this helps :)

Specific and targeted - loved it!

My 2cents, hobby is a "nice to have" activity, and you want your product to solve a pain. I haven't seen the product, if you can't provide a link I'll be able to dive deeper.

Seems straightforward, you can't go wrong with this :D

It's pretty clear, although I'll try to dive a bit deeper, for instance, "Get More RSVPs By Tracking & Interacting with Your Invitees", or something along that line.

From your slogan, I understand that your product is related to team collaboration, but what I didn't understand is how, and how can I use it. After I checked your website, I got a better understanding of what's the product about, but I'd recommend to A/B it, with a clear cut message that might differentiate the product from the competition. For a well-established product like Slack, it might have worked, my 2 cents, hope it helps.

Clear, and addresses the target audience, not an easy slogan, and I think you cracked it.

Straightforward, loved it, I can't add anything. Or maybe one thing, if GS already has these functions, add the word "Better" or something along that line before.

Straightforward, you solve the "time-consumption" issue your potential users have with landing pages. You nailed it :)

It's more difficult with services, win more clients is def a pain, but I'd also try to A/B test "Stand out" (corny, yet effective), or even get bold and go for "Designing Client Success By Creating Memorable Brands", or something along that line. Hope this helps :)
