Welcome to the Q&A Forum

Really easy, just: s. It probably will already be visible in the parameters found by GWT itself.

When I got started with blogging, I would select the keywords that I would naturally search. Now, you can do the same with bit more data. When you type-in the keywords in Google Search, make a pick based on the suggested keywords. Then create article based on that. This will get you started. Then track your analytics data and refine your keyword list based on keywords that drive traffic.

I checked my webmaster, and it said that I didn't have to do anything with url parameters. Should I still try to fix it?

The Moz SEO guide is a good start. Also, I'd run the Moz tools on your website, and use our Help Hub at http://moz.com/help/pro to help you understand the results you're getting and how to help fix up your website. Do feel free to ask specific questions in Q&A, too!

Hi Taimoor, I'm a little bit confused by 'too many links' - which report are you looking at? Is it an on-page report? If you're talking about excessive internal links then whilst this won't harm the page, but you may find you have issues getting all of the pages on your indexed (if the excessive internal linking is a deliberate information architecture decision and the only way the search engine robots can crawl and index the pages on your site). If you're talking about excessive external links then your page may be considered spammy by the search engines (particularly if those links are not pointing to high quality/trustworthy sites). I hope this helps, Hannah
