Not there yet, but has potential
My first impression? Well, weblium.com itself loaded in 13 seconds...not off to a good start lol! http://prntscr.com/o3gcx0 Also, the pricing is a hard sell for us, because right now we use namecheap hosting, free cloudflare cdn/ssl, and cloudflare registar for our clients which ends up being 1/2 the price for 3x the websites. But if the hosting is super reliable (with Google cloud hosting is), and EVERYTHING is truly included (I'm talking premium SEO, image optimization and resizing, speed, cdn, ssl, domain name, etc.), then this could work.
I really like their vision of becoming the quickest website builder, and an all-in-one solution. There is just so much to manage these days with wordpress and all the SEO necessities that I think people could really consider this as legit alternative.
However, for agencies to really get onboard, there needs to be improvement in the SEO tools something similar to what Yoast Premium does should be enough. There also needs to be something similar to what ShortPixel does for wordpress sites, where images are automatically resized and served by a cdn like cloudflare if they are serious about being the fastest and truely an all-in-one solution. Optimizing pictures takes far to long, especially the resizing part.
Certainly going to play around with it some more, and am going to hang onto this deal hoping that they will consider the above suggestions. After watching the webinar, and an interview with the founder, I feel a little more confident that they will deliver. Might be a good investment...
