    We have a zend framework that is complex to program if you ask me, and since we have 20k+ pages that we need to get proper titles to and meta descriptions, i need to ask if we use Javascript to handle page titles (basically the previously programming team had NOT set page titles at all) and i need to get proper page titles from a h1 tag within the page.

    current course of action which we can easily implement is fetch page title from that h1 tag being used throughout all pages with the help of javascript, But this does makes it difficult for engines to actually read what's the page title? since its being fetched with javascript code that we have put in, though i had doubts, is anyone one of you have simiilar situation before? if yes i need some help!

    Update: I tried the JavaScript way and here is what it looks like http://islamicencyclopedia.org/public/index/hadith/id/1/book_id/106  i know the fact that google won't read JavaScript like the way we have done with the website, But i need help on "How we can work around this issue"  Knowing we don't have other options.

      Your welcome. Interesting question. My answer is that if the HTML TITLE is set with client side JavaScript then it's has little change of being picked up as the title by crawlers or Google. Let's say we alter the node element Title value with like this:

      In this case it will alter the value after the hard coded HTML title was send to the browser. It would need the crawler to load the document in full and read the HTML title value only after fully rendering it as if it where a human user. This is not likely.

      Then we could also try a document write to construct the HTML HEAD tag Title as a string to use for the browser as the title like this:

      Will not work as the title text is not actually altered after evaluation of the script line.

      This does not work because the title is not set but because it's not actually printed to the browser as a string. The source code for the title still looks like this in to any browser:

      As you can see the script does not print the result string of the evaluation to the browser but still sets the value of the document object model node HTML TITLE to the value it evaluates to.

      Try it for yourself with this dummy page I made just to be certain.
      http://www.googlewiki.nl/test/seojavascripttest2.html And this is the DOM info for this page http://www.googlewiki.nl/seo-checker/testanchor.php?url=http://www.googlewiki.nl/test/seojavascripttest2.html&anchor=test

      Or am I missing something here?

      Hope this helps.

        Google can read Javascript, but only certain types and implemetations. Is there a way you can set this swap out to happen on the database or server side? That might be the best way to get the live text readable, as most likely the javascript is being rendered and displayed after the initial crawl of the page. Even if it is a milisecond later, Google might not allow/catch it.

          Any javascript effor is invalid for SEO. Google doesn't read them.

          You can try to make it on PHP, it's not complex, search your an replace with meta desc=$var and <title>$var2 (and, also, </head>). Then you can set the meta desc and page title with a variable in your code, and then this effor effectively have SEO value, because when the search engine fetch the page they have title and desc.</p> <p>Maybe this is more work than JS form, but also it's better for SEO and web itself (The JS run takes time on client side).</p></title>

            Thank you Daniel for the input, Since the code is all messed up and i can't convince the Board to redo the site from scratch. i'll have to go with small tricks with title tags and descriptions to be set, with JavaScript as i just tried, it worked and it now does fetch all the titles and displays them on the browser title, without any significant change in the actual code except for the addition of JavaScript that i just tried.

            But i did a test run with Rich snippet testing tool to see what Google pulls in as preview for search results, and it didn't show anything, No title and No description .. alas! So i guess it does mean using JavaScript to fetch title & description won't help? I'm still not sure.

            So now the real question i have in mind; Does this Javascript technique that we just used, will it be of any good SEO wise or will have any value?

              Hi... I would not prefer a client side approach to this. If it's readable depends on the script itself. Although some JS fans will say this alright I would prefer to do this server side with php, or similar, and make a template that does this rewrite. It's not to hard. Or why not a batch run to modify all pages once to hardcode the correct title in the page? Have some scripts that can do this for you if you would like.

              Hope this helps.

                For FAQ Schema markup, do we need to include every FAQ that is on the page in the markup, or can we use only selected FAQs?

                The website FAQ page we are working on has more than 50 FAQs. FAQ Schema guidelines say the markup must be an exact match with the content. Does that mean all 50+ FAQs must be in the mark-up? Or does that mean the few FAQs we decided to put in the markup are an exact match?

                Would You Redirect a Page if the Parent Page was Redirected?

                Hi everyone! Let's use this as an example URL: https://www.example.com/marvel/avengers/hulk/ We have done a 301 redirect for the "Avengers" page to another page on the site. Sibling pages of the "Hulk" page live off "marvel" now (ex: /marvel/thor/ and /marvel/iron-man/). Is there any benefit in doing a 301 for the "Hulk" page to live at /marvel/hulk/ like it's sibling pages? Is there any harm long-term in leaving the "Hulk" page under a permanently redirected page? Thank you! Matt

                Should I apply Canonical Links from my Landing Pages to Core Website Pages?

                I am working on an SEO project for the website: https://wave.com.au/ There are some core website pages, which we want to target for organic traffic, like this one: https://wave.com.au/doctors/medical-specialties/anaesthetist-jobs/ Then we have basically have another version that is set up as a landing page and used for CPC campaigns. https://wave.com.au/anaesthetists/ Essentially, my question is should I apply canonical links from the landing page versions to the core website pages (especially if I know they are only utilising them for CPC campaigns) so as to push link equity/juice across? Here is the GA data from January 1 - April 30, 2019 (Behavior > Site Content > All Pages😞

                If a page ranks in the wrong country and is redirected, does that problem pass to the new page?

                Hi guys, I'm having a weird problem: A new multilingual site was launched about 2 months ago. It has correct hreflang tags and Geo targetting in GSC for every language version. We redirected some relevant pages (with good PA) from another website of our client's. It turned out that the pages were not ranking in the correct country markets (for example, the en-gb page ranking in the USA). The pages from our site seem to have the same problem. Do you think they inherited it due to the redirects? Is it possible that Google will sort things out over some time, given the fact that the new pages have correct hreflangs? Is there stuff we could do to help ranking in the correct country markets?

                Company Name in Home Page Title? If and Where?

                My guess is you want to do the  {title} | {company name} format as I would suspect Google gives slightly more weight to the words at the beginning of the title?   (This is assuming your company name isn't a generic word or you are specifically trying to rank your home page for your company name when it isn't ranking well already) But what about cases where you have like 5 or 6 keywords that are really important and used in the title gives you like 50 characters and your company name pushed it up to like 65 increasing the chance Google will use some other source to list the name of your home page in the search results? Obviously one can experiment, but wondering what the general consensus is - long keyword title, or longer title with company name?  The company name can be included in the meta description and the domain name of the url displayed also gives the indication to the company.  But maybe the algo "respects" long itles that have company name more than ones without as then it looks more like a keyword stuffing title?  So many factors to consider.  Yes - on page SEO isn't just about the title, but for this thread I'm just talking home page title.

                What are best page titles for sub-domain pages?

                Hi Moz communtity, Let's say a website has multiple sub-domains with hundreds and thousands of pages. Generally we will be mentioning "primary keyword & "brand name" on every page of website. Can we do same on all pages of sub-domains to increase the authority of website for this primary keyword in Google? Or it gonna end up as negative impact if Google consider as duplicate content being mentioned same keyword and brand name on every page even on website and all pages of sub domains? Thanks

                Is it a problem to use a 301 redirect to a 404 error page, instead of serving directly a 404 page?

                We are building URLs dynamically with apache rewrite.
                When we detect that an URL is matching some valid patterns, we serve a script which then may detect that the combination of parameters in the URL does not exist. If this happens we produce a 301 redirect to another URL which serves a 404 error page, So my doubt is the following: Do I have to worry about not serving directly an 404, but redirecting (301) to a 404 page? Will this lead to the erroneous original URL staying longer in the google index than if I would serve directly a 404? Some context. It is a site with about 200.000 web pages and we have currently 90.000 404 errors reported in webmaster tools (even though only 600 detected last month).

                Can too many "noindex" pages compared to "index" pages be a problem?

                Hello, I have a question for you: our website virtualsheetmusic.com includes thousands of product pages, and due to Panda penalties in the past, we have no-indexed most of the product pages hoping in a sort of recovery (not yet seen though!). So, currently we have about 4,000 "index" page compared to about 80,000 "noindex" pages. Now, we plan to add additional 100,000 new product pages from a new publisher to offer our customers more music choice, and these new pages will still be marked as "noindex, follow". At the end of the integration process, we will end up having something like 180,000 "noindex, follow" pages compared to about 4,000 "index, follow" pages. Here is my question: can this huge discrepancy between 180,000 "noindex" pages and 4,000 "index" pages be a problem? Can this kind of scenario have or cause any negative effect on our current natural SEs profile? or is this something that doesn't actually matter? Any thoughts on this issue are very welcome. Thank you! Fabrizio
