Understanding Redirects and Canonical Tags in SEO: A Complex Case
Hi everyone, nothing serious here, i'm just playing around doing my experiments 🙂
Technical SEO | | chueneke
but if any1 of you guys understand this chaos and what was the issue here, i'd appreciate if you try to explain it to me. I had a page "Linkaufbau" on my website at https://chriseo.de/linkaufbau. My .htaccess file contains only basic SEO stuff: # removed ".html" using htaccess RewriteCond %{THE_REQUEST} ^GET\ (.*)\.html\ HTTP RewriteRule (.*)\.html$ $1 [R=301,L] # internally added .html if necessary RewriteCond %{REQUEST_FILENAME}.html -f RewriteCond %{REQUEST_URI} !/$ RewriteRule (.*) $1\.html [L] # removed "index" from directory index pages RewriteRule (.*)/index$ $1/ [R=301,L] # removed trailing "/" if not a directory RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} /$ RewriteRule (.*)/ $1 [R=301,L] # Here’s the first redirect: RedirectPermanent /index / My first three questions: Why do I need this rule? Why must this rule be at the top? Why isn't this handled by mod_rewrite? Now to the interesting part: I moved the Linkaufbau page to the SEO folder: https://chriseo.de/seo/linkaufbau and set up the redirect accordingly: RedirectPermanent /linkaufbau /seo/linkaufbau.html I deleted the old /linkaufbau page. I requested indexing for /seo/linkaufbau in the Google Search Console. Once the page was indexed, I set a canonical to the old URL: <link rel="canonical" href="https://chriseo.de/linkaufbau"> Then I resubmitted the sitemap and requested indexing for /seo/linkaufbau again, even though it was already indexed. Due to the canonical tag, the page quickly disappeared. I then requested indexing for /linkaufbau and /linkaufbau.html in GSC (the old, deleted page). After two days, both URLs were back in the serps:: https://chriseo.de/linkaufbau https://chriseo.de/linkaufbau.html this is the new page /seo/linkaufbau

242d5bfd-af7c-4bed-9887-c12a29837d77-grafik.png Both URLs are now in the search results and all rankings are significantly better than before for keywords like: organic linkbuilding linkaufbau kosten linkaufbau service natürlicher linkaufbau hochwertiger linkaufbau organische backlinks linkaufbau strategie linkaufbau agentur Interestingly, both URLs (with and without .html) redirect to the new URL https://chriseo.de/seo/linkaufbau, which in turn has a canonical pointing to https://chriseo.de/linkaufbau (without .html). In the SERPs, when https://chriseo.de/linkaufbau is shown, my new, updated snippet is displayed. When /linkaufbau.html is shown, it displays the old, deleted page that had already disappeared from the index. I have now removed the canonical tag. I don't fully understand the process of what happened and why. If anyone has any ideas, I would be very grateful. Best regards,

Is it a good idea to use the rel canonical tag to refer to the original source?
Sometimes we place our blog post also on a external site. In this case this post is duplicated. Via the post we link to the original source but is it also possible to use the rel canonical tag on the external site? For example: The original blogpost is published on http://www.original.com/post The same blogpost is published on http:///www.duplicate.com/post. In this case is it wise to put a rel canonical on http://www.duplicate.com/post like this: ? What do you think? Thanks for help! Robert

Title tag code
Hi, I have a couple of websites where I can't define the title tag (CMS does not support it) on a few default pages. On these pages "the system" just uses the primary/main title tag (from the frontpage) and my programming skills (as if I have any...!) have not been able to make a html code or something to override the main title tag on these specific pages. Does this make sense at all and can anyone give me a hint, a code to try out or something? Problem is that I now have 3 pages with the same title tag which in terms of SEO isn't too good, so to say... Thanks in advance. Jan

Local SEO best practices for multiple locations
When dealing with local search for a business with multiple locations, I've always created an individual page for each location. Aside from the address and business name being in there, I also like to make sure the title tag and other important markup features the state/city/suburb, or, in the case of hyper-local, hyper-competitive markets, information more specific than that. It's worked very well so far. But, the one thing you can always count on with Local is that the game keeps changing. So I'd like to hear what you think... How do you deal with multiple locations these days? Has Google (and others, of course) advanced far enough to not mess things up if you put multiple locations on the same page? (Do I hear snickers? Be nice now) How does Schema.org fit in to your tactics in this area, if at all? Cheers (Edit: dear SEOmoz, stop eating my line breaks)

Canonical URLs and screen scraping
So a little question here. I was looking into a module to help implement canonical URLs on a certain CMS and I came a cross a snarky comment about relative vs. absolute URLs being used. This person was insistent that relative URLs are fine and absolute URLs are only for people who don't know what they are doing. My question is, if using relative URLs, doesn't it make it easier to have your content scraped? After all, if you do get your content scraped at least it would point back to your site if using absolute URLs, right? Am I missing something or is my thinking OK on this? Any feedback is much appreciated!

Did I implement the Canonical Correctly?
Hello, I am trying for the first time to implement a canonical redirect on a page and would really appreciate it if someone could tell me if this was done correctly. I am trying to do a canonical redirect: -from http://www.diamondtours.com/default.aspx -to http://www.diamondtours.com/ As you will see in the source code of the default.aspx page, the line of code written is: <link rel="canonical" href="http://www.diamondtours.com" /> Is this correct? Any guidance is greatly appreciated. Jeffrey Ferraro
