In addition to Lynns point it would be worth discounting these URL parameters in Google webmaster tools and bing in order to avoid any possible duplicate content issues, rather than leaving it to them to work out which will also avoid the case Lynn mentions for organic search (A case we also expoerienced with a client!)

When a site links to another it passes that site some of its authority and SEO benefit. Only links that are 'follow' will do this, a nofollow link will not. These values are set by the site owner, often on blogs etc all links are set to nofollow to avoid comment spam where people are trying to get links to their site.

If your comments and links are relevant and add value to an article by all means comment and drop a link, you will be able to check if they are no follow or not to. This post by Rand, although not written to answer this specific question, is useful to illustrate the difference between these links and their relationship in passing link juice.

A higher domain authority site as a rule of thumb is generally better yes, but there are other important factors involved that Google will take into account, then there are considerations about having a link in the comments section as opposed to elsewhere on a page. Again i recommend a read through this post by Rand, Not all links are created equal.

The two articles above should help familiarise yourself with the nuances of link building and the more advanced issues, but if you would like a simple yes no answer then yes, leaving a link in the comments section of a article that is a follow link, can help your SEO. But use this tactic as one part of a balanced link building strategy.

Its often a case of logistics in updating a site to be responsive design, the only way the same URL can serve dynamic content to mobile and desktop devices. Previously many sites have had to create alternate mobile sites.

So while responsive is now the recomended approach, many sites still use subdomains or directorys. This useful post also casts light on when these multiple methods are most suitable. When Responsive Design is not an option.

Hope this helps.

Ok, well you can set canonical tags in Yoast. Without seeing you site set up or the offending pages i am hesitant to give more detailed advice. Best of luck.

Ok, well in wordress you can access the HTML by going to Appearance>editor and you will see the options on the right hand side. However do you use any SEO plugins such as Yoast?

The canonical tag is a Meta tag in the head section of your page HTML, If you have access to this you just need to go in and remove that line of code. If you do not you will need to tell your webdeveloper which pages these appear on so that they can go in and remove them.

The following link is to Googles guidelines on the use of the canonical tag.

If you would like more specific guidance if you pop down an example URL myself or someone else will be able to take a look for you.

Hope this helps.

I forgot to include, keywords do not need to be exclusive to an individual page, they can be targeted on multiple pages, but having the specific landing page will likely be the most effective area on the site for concentrated on-page SEO tactics.

I would also agree with Baldea and David here, be careful not to Keyword stuff the Home page.

You can include your desired terms within elements of the page if they are relevant / to help the home page rank for those terms, but a product specific page is always going to give you the most scope to target all page elements effectively.

The Page title is only one element, SEOmoz's on page optimisation tool should be useful for you in working out how effectively you are targeting the phrase and what trade-offs are available to you.

Thats great thanks very much for your help Martjin. Would have got back to you sooner but was testing it out, just needed to put a .* and added a .* to the end to to deal with our multitude of URL paramaters. Happily watching the data roll on in now.

Hi,

Would really appreciate some help with this. I have been experimenting with RegEx to achieve this but as I’ve never used it before am currently failing miserably.

We have conversion pages i need to set goals for that are formatted as below:

https://www.domain.co.uk//Application_Form/(S(ewhbqp5cki0mppuzukunkqno))/enterCardDetails.aspx

I need to remove the (s(xxx)) section from the URL as rather than one pages i currently have thousands of unique URL's. What’s catching me out is that as it’s not a URL parameter I can’t discount and as half way through can’t just do head matches etc to /entercarddetails

Help would be much appreciated.

Thanks.
