      I found a little difficult for me to do a canonical tag in my PHP.

      On-Page Report Card

      We check to make sure that IF you use canonical URL tags, it points to the right page. If the canonical tag points to a different URL, engines will not count this page as the reference resource and thus, it won't have an opportunity to rank. If you've not made this page the rel=canonical target, change the reference to this URL. NOTE: For pages not employing canonical URL tags, this factor does not apply.

      I don't know how to tidy my PHP

      Any suggestion.

        Thanks Shane,

        That was very simple and to the point.  I am doing SEO on a php site where there's a header and a footer and I didin't know how to add the canoical tag to the header correctly and the On page.  Thanks again.

          Is this a CMS, or are you trying to make the canonical only impact certain pages or conditions? The canonical tag is just an HTML tag, in the header. It doesn't really need special code, unless the target of the canonical has to be created dynamically. Unfortunately, then the solution depends entirely on your implementation (it's not one-sized-fits-all across all PHP sites).

          If you could describe the structure of the site a bit (example URLs and how they're created) without revealing the site, that could help us pin it down.

            Hi,

            In my site, I use a php expression - as such -

            header.php -

            On page -

            $canonical = "http://www.domain.com";

            Here is a recent Blog Post if the above code does not help

              What could cause Google to not honor canonical URLs?

              I have a strange situation on a website, when I do a Google query of site:example.com all the top indexed results appear to be queries that users can perform on the website. So any random term the user searches for on the website for some reason is causing the search result page to get indexed - like example.com/search/query/random-keywords However, the search results page has a canonical tag on it that points to example.com/search, but that doesn't seem to be doing anything. Any thoughts or ideas why this could be happening?

              Trailing slash URLs and canonical links

              Hi, I've seen a fair amount of topics speaking about the difference between domain names ending with or without trailing slashes, the impact on crawlers and how it behaves with canonical links.
              However, it sticks to domain names only.
              What about subfolders and pages then? How does it behaves with those? Say I've a site structured like this:
              https://www.domain.com
              https://www.domain.com/page1 And for each of my pages, I've an automatic canonical link ending with a slash.
              Eg. rel="canonical" href="https://www.domain.com/page1/" /> for the above page. SEM Rush flags this as a canonical error. But is it exactly?
              Are all my canonical links wrong because of that slash? And as subsidiary question, both domain.com/page1 and domain.com/page1/ are accessible. Is it this a mistake or it doesn't make any difference (I've read that those are considered different pages)? Thanks!
              G

              Exact Match Domain & Title Tag / URL

              I currently own an exact match domain for my keyword.  I have it set up with multiple pages and also a blog.   The home page essentially serves as a hub and contains links to all the pages and the blog. My targeted keyword is on its own page and I made the title tag the same as my keyword. As an example the URL for my targeted post looks like this: benefitsofrunningshoes.com/benefits-of-running-shoes I have solid, non-spammy content and clean whitehat earned backlinks directing to that specific page. My concern right now is that the URL looks kinda spammy.  The website has been live for about a week and the home page ranks well enough but my targeted page is no where to be found.  (it does show up if I manually search via search command "site:benefitsofrunningshoes.com"). I'm wondering if it is acceptable to use the exact keyword in title tag / page url if it is also in the domain as an EMD? Should I change the title tag and leave the URL in?  Or should I completely change the title tag and URL and 301 redirect to the new page?  I appreciate any help!

              Isnt it better to have headlines in H1 and H2 tags instead of p tags?

              I am working with a simple site http://http://lightsigns.com/Uniko_Manufacturing_Limited.html They seek more SEO traffic. However, the two big headlines that read "Wholesale Supply to the Sign and Display Industries" which is on line 241 and 242 of the source code, its in a p tag, i.e. <p <span class="webkit-html-tag">style</p <span>="padding-top: 0pt; " class="paragraph_style_1">Wholesale Supply to the and <p <span class="webkit-html-tag">style</p <span>="padding-bottom: 0pt; " class="paragraph_style_1">Sign and Display Industries Likewise, the product titles are in p tags, also. For example, on the Slide-in Light Box product page, http://lightsigns.com/Slide_In_light_box.html , I have done keyword research and no one is using the words slide in light box.Plus, it is also a p tag, ie. line 43 reads style="padding-bottom: 0pt; padding-top: 0pt; " class="paragraph_style">Slide-in Light Box If I suggest that they make an H2 tag with SEO-optimized keywords such as Display Light Box - Slide-In LIght Box, would this indeed help SEO? In summary, is it correct to say that H1 and H2 tags are stronger signals to the search bots of what the page is about?

              The Mysterious Case of Pagination, Canonical Tags

              Hey guys, My head explodes when I think of this problem. So I will leave it to you guys to find a solution... My root domain (xxx.com) runs on WordPress platform. I use Yoast SEO plugin. The next page of root domain -- page/2/ -- has been canonicalized to the same page -- page/2/ points to page/2/ for example. The page/2/ and remaining pages also have this rel tags: I have also added "noindex,follow" to page/2/ and further -- Yoast does this automatically. Note: Yoast plugin also adds canonical to page/2/...page/3/ automatically. Same is the case with category pages and tag pages. Oh, and the author pages too -- they all have self-canonicalization, rel prev & rel next tags, and have been "noindex, followed." Problem: Am I doing this the way it should be done? I asked a Google Webmaster employee on rel next and prev tags, and this is what she said: "We do not recommend noindexing later pages, nor rel="canonical"izing everything to the first page." (My bad, last year I was canonicalizing pages to first page). One of the popular blog, a competitor, uses none of these tags. Yet they rank higher. Others following this format have been hit with every kind of Google algorithm I could think of. I want to leave it to Google to decide what's better, but then again, Yoast SEO plugin rules my blog -- okay, let's say I am a bad coder. Any help, suggestions, and thoughts are highly appreciated. 🙂 Update 1: Paginated pages -- including category pages and tag pages -- have unique snippets; no full-length posts. Thought I'd make that clear.

              Special characters in URL

              Hi There, We're in the process of changing our URL structure to be more SEO friendly. Right now I'm struggling to find a good way to handle slashes that are part of a targeted keyword. For example, if I have a product page and my product title is "1/2 ct Diamond Earrings in 14K Gold" which of the following URLs is the right way to go if I'm targeting the product title as the search keyword? example.com/jewelry/1-2-ct-diamond-earrings-in-14k-gold example.com/jewelry/12-ct-diamond-earrings-in-14k-gold example.com/jewelry/1_2-ct-diamond-earrings-in-14k-gold example.com/jewelry/1%2F2-ct-diamond-earrings-in-14k-gold Thanks!

              Old URL redirect to New URL

              Alright I did something dumb a year a go and I'm still paying for it. I changed my hyphenated URL to the non-hyphenated version when I redesigned my website. I say it was dumb because I lost most of my link juice even though I did 301 redirects (via the htaccess file) for almost all of the pages I could find in Google's index. Here's my problem. My new site took a huge hit in traffic (down 60%) when I made the change and even though I've done thousands of redirects my old site is still showing up in the SERPS and send much if not most of my traffic. I don't want to take the old site down in fear it will kill all of my traffic. What should I do? Is there a better method I should explore then 301 redirects? Could the other site be affecting my current rank since it's still there? (FYI...both sites are built on the WP platform). Any help or ideas are greatly appreciated. Thank you! Joe
