I'm doing a crawl analysis for a website and finding all these duplicate URLs with "null" being added to them and have no clue what could be causing this.
-
Does anyone know what could be causing this? Our dev team thinks it's caused by mobile pages they created a while ago but it is adding 1000's of additional URLs to the crawl report and being indexed by Google. They don't see it as a priority but I believe these could be very harmful to our site.
examples from URL string:
uruguay-argentina-chilenullnull/days
rainforests-volcanoes-wildlifenullnull/reviews
of-eastern-europenullnullnullnull/hotels -
Hi there,
This looks to be something to do with a URL generator that is dynamically creating URLs based on certain categories being present.
The downside being that those categories look to have been removed, hence the 'null' values being passed through.
I would push this back to your developers as a serious issue, there could be a large amount of duplication occurring if you're not careful.
All the best,
Sean

Making a website menu + structure + hierarchies + kw research
When making a new website structure I assume we all think about SEO but at the same time as we can't forget UX.

Moving servers which means moving ip address but using the same URL. Would it harm the website's SEO?
Hello everyone, The server (in-house) which we use to host our website is a bit old. We are using CDN77 for our static content. What if I move all our website to the CDN service? meaning I use their storage capability and just have our url point to the IP address they provide. Would that hurt our rankings?

Looking to remove SSL because it is causing very slow website download speeds. Does WP have a plugin that redirects SSL urls to non SSL urls?
After some extended debate with our web development team we are considering dropping the SSL from our website because it is adding almost 2 additional seconds to our download speeds. We know there is a SEO boost from having a SSL but we believe the extended download speeds maybe outweighing the benefit. However we are concerned about the SEO implications of having no method possible of redirect SSL to non SSL webpages. Does anybody know of a Wordpress Plugin that can force redirect SSL urls to non SSL urls?

E-Commerce Website Architecture - Cannibalization between Product Categories and Blog Categories?
Hi, I have an e-commerce site that sells laptops. My main landing pages and category pages are as follows:
Web Design | | BeytzNet
"Toshiba Laptops", "Samsung Laptops", etc. We also run a WP blog with industry news.
The posts are divided into categories which are basically as our landing pages.
The posts themselves usually link to the appropriate e-commerce landing page.
For example: a post about a new Samsung Laptop which is categorized in the blog under "Samsung Laptops" will naturally link somewhere inside to the "samsung laptops" ecommerce landing page. Is that good or do the categories on the blog cannibalize my more important e-commerce section landing pages? Thanks0 -

The use of foreign characters and capital letters in URL's?
Hello all, We have 4 language domains for our website, and a number of our Spanish landing pages are written using Spanish characters - most notably: ñ and ó. We have done our research around the web and realised that many of the top competitors for keywords such as Diseño Web (web design) and Aplicaión iPhone (iphone application) DO NOT use these special chacracters in their URL structure. Here is an example of our URL's EX: http://www.twago.es/expert/Diseño-Web/Diseño-Web However when I simply copy paste a URL that contains a special character it is automatically translated and encoded. EX: http://www.twago.es/expert/Aplicación-iPhone/Aplicación-iPhone (When written out long had it appears: http://www.twago.es/expert/Aplicación-iPhone/Aplicación-iPhone My first question is, seeing how the overwhelming majority of website URL's DO NOT contain special characters (and even for Spanish/German characters these are simply written using the standard English latin alphabet) is there a negative effect on our SEO rankings/efforts because we are using special characters? When we write anchor text for backlinks to these pages we USE the special characteristics in the anchor text (so does most other competitors). Does the anchor text have to exactly I know most webbrowsers can understand the special characters, especially when returning search results to users that either type the special characters within their search query (or not). But we seem to think that if we were doing the right thing, then why does everyone else do it differently? My second question is the same, but focusing on the use of Capital letters in our URL structure. NOTE: When we do a broken link check with some link tools (such as xenu) the URL's that contain the special characters in Spanish are marked as "broken". Is this a related issue? Any help anyone could give us would be greatly appreciated! Thanks, David from twago
