Welcome to the Q&A Forum

In addition to above tools, try http://www.seoprofiler.com (there is a free subscription option). then go to Organic Keyword Spy. You can find keywords that your competitors rank for as well as your website rank for. I found so many new keywords that I didn't know my client's site is ranking for (and have a change to rank better).

Hello,

I have found that from an HTML  (not xml) sitemap of a website, a page has been listed twice. Is it okay or will it be considered duplicate content?

Both the links use same anchor text, but different urls that redirect to another (final) page. I thought ideal way is to use final page in sitemap (and in all internal linking), not the intermediate pages. Am I right?

I would give it a week+. They have to review the changes.
