How to set up internal linking with subcategories?

[wplodge]

I'm building a new website and am setting up internal link structure with subcategories and hoping to do so with best Seo practices in mind.  When linking to a subcategory's main page, would I make the internal link  www.xxx.com/fishing/ or www.xxx.com/fishing/index.html or does it matter?  I'm just trying to avoid duplicate content I guess, if Google saw each page as a separate page.  Any other cautions when using subdirectories in my navigation?

First thing you need to do is determine which is your preferred URL (probably www.site.com/fishing/). Once you have that, the key to good linking is consistency (using the same, preferred URL for any given page you're linking to & also using descriptive, naturally-occurring anchor text that's relevant to the page's content).

The fact that your site has other versions of the page (/fishing/ and /fishing/index.html) means that you probably need to implement a solution to prevent dup content issues - either 301 redirect all variations to the preferred URL or implement rel=canonical tags to tell search bots which is the preferred URL to include in its index.

I hope this helps!

Hello,

Duplicate content is usually pretty simple to deal with see Sheena's response.

I would recommend at this point in design looking at the URL structure not primary as trying to avoid a negative, rather how to incorporate the most positives. That is how can you get the most SEO value out of the url's. Since you're at the point where you can make these changes, then now is the time to evaluate how you want your site to appear to the users and search engines.

Here are 2 Good, nay VERY GOOD post on Moz to help with this process.

I hope this is helpful,

It seems like you are actually asking 2 questions in one. Let's approach them both separately.

Should you include index.html or not in your structure? Personally, I think the cleanest URL structure works the best. Get rid of any URL parameters that do not offer any benefit. Cleaner URLs not only look better, but are easier to read and share. Who really wants to share DOMAIN.com/fishing.index.html vs DOMAIN.com/fishing. It may seem petty, but in the grander scheme of things it will just work better. If you do this in one area of your site, keep it consistant through the whole site

As to making sure that Google only indexes one version, this can be done through the URL parameter redirects on your server. You can create rules where the URL automatically strips out any additional URL items, and redirects to the proper version. Once you create your sitemap, make sure to only include the versions of your URL you want indexed. One thing I have found in my entire SEO career is this: The easier and clearer you paint a picture for Google about your site, the better your results will be.
