How long will it take since installing the plugin to get my siteto first page?

I don’t think you can get an answer to that. The plugin can help with SEO, but there’s no way of knowing when, if ever, your website will be on the first page of Google.

It’s wrong to think that this plugin will get you to page one of Google.

Using this plugin is about the ONLY thing you can directly do yourself to get ranked higher, but it’s only useful for telling Google what to find on your page. It’s up to Google to determine if you have the credibility to be on page one and they use hundreds of factors to determine that.

If you want to get to page one then you need to think about how to get people to link to you as an authority on your subject.

You may want to check my free training I did on this here about SEO:

@meshmarketer, in future if you are to link to SEO resources could you link to the official ones from the search engines? It may indeed be better to just forward the guy onto Google’s forums: https://groups.google.com/forum/

Another thing, how to get something like this under your link?

What I mean are those links under first main link, subpages.
