Let me add, while I have support for recaptcha, I urge you to make the internet a better place and not use it. Try the Honeypot stack that comes with F6 forms. It’s much nicer and people have had good success with it.
Therein might lie part of the problem. Even after you manage to get your site indexed by Google (which apparently hasn’t happened yet - but is simple to do at the URL Doug provided just above), Google will almost certainly not make your site “quickly found” on the web. Why? Because the competition for the same keywords have been at it for a long time and it is in Google’s best interest to serve up the best websites. Those websites have a track record, and Google knows which sites generates clicks and which sites people then spend time on. Those are the sites that get promoted to the top of Search Engine Results Pages. Google will most likely not demote sites already at the top of the SERP for a newcomer, but if you’ve built a great site and you’ve followed the right SEO steps, Google will, over time raise your site in the results. But, at least in my experience, it will take time - four months to a year to really see great results. In the meantime, be sure to submit your site to Google, Bing, Yandex, Apple, get on Google My Business, Bing Places, Apple Maps Connect, get a Facebook page, and continue to hone your site.
In addition to what @dave and @joeworkman have mentioned, you need to keep in mind that SEO Helper is just a “helper”. It’s not going to get you to the top of SERPs (search engine results page) On its own.
Good, original, well-organized content is what gets you to the top, and Even that takes time.
If you need to be found fast, then you’ll need to think about it paid advertising like an AdWords campaign.
If it was as simple as buying any SEO tool to get you to the top then all your competitors would have already done it.
If you want to submit your site to search engines manually then yes you need one, but RapidWeaver produces one for you (unless you’ve turned it off in advanced settings. It’s called sitemap.xml in the root directory.
