Does crawlspa really crawl sites? Or is it just yet another "prerender-like" SaaS? Why should someone use your service instead of existing ones? What is your added-value compared for example to seo4ajax.com?
It doesnt crawl (although I will offer this soon) but it doesnt require entering any domains or sitemaps like the other options (easier to configure). You just submit your top level domain and let google do the crawling.
FYI, seo4ajax.com doesn't need any sitemap (but it generates it) and is very easy to configure. Actually, I still don't see where your service is better currently...
The crawler is a bit hands on. Crawlspa refreshes the cache in the background after each request. For sites with frequently updated content, having to recrawl may become a headache.
The crawler is just mandatory if you don't want to penalize the site with long response times or to prevent serving 5xx pages the first day you launch your Ajax site in production. BTW, be prepared for headaches, they are some surprises when dealing with search engines and their escaped_fragment implementation ;). Anyway, welcome on the SEO for Ajax SaaS providers (disclaimer: I'm one of the SEO4Ajax co-founder).
Cool, ill be interested in seeing what you start charging after the beta :) Good luck with it, its reassuring that im not the only one to have thought this to be a good idea.
If you are interested by the pricing you can have a look at prerender, brombone, getseojs, ajaxsnapshots or blitline. You'll see that it varies a lot.
Yep, I thought brombone had an interesting pricing model :) I wonder if they managed to get any signups.
