      Is there an advantage/disadvantage to adding an .html suffix to urls in a CMS like WordPress. Plugins exist to do it, but it seems better for the user to leave it off. What do search engines prefer?

        After I finished work, I will dig through my history and can hopefully deliver.

        Update: I spent 1 hour going through my browser history and I was not able to find it. Kinda freaks me out. Sorry.

          I would love to see the study if you can find the link later. I agree sometimes study results conflict with prior conceptions and I have been mistaken before, but those study results really sound counter intuitive.

            There are actually some studies that can be found on the internet that suggest that the CTR correlates with the extension shown on the SERP, namely .html is supposedly having a positive impact on the CTR of up to 200%.

            I was trying hard to find the website I read it on, but on the quick I couldn't find it. It contained a "study" on it with eyetracking and it made sense.

            I've personally never run a test on it, but I decided to add html to our documents by means of Mod Rewrite.

            As far as search engines are concerned, it does not matter at all. But overall, the visitor should be more important and seeing that it does not negatively impact rankings, it's worth a try.

              When possible, always remove the .html or any technology suffix such as .php, .htm, etc. A few reasons:

              • this information offers no value to users nor search engines

              • it needlessly increases the length of your URL

              • it offers hackers an additional piece of information about your web server files. You want to make the bad guys work as hard as possible

              • it helps a lot with SEO when you change technologies. There is good reason for .html pages to move to .php pages. When that change is made, all the pages on a site need to be 301'd. The entire process is a big waste of link juice for the entire site which could be avoided if the technology extension did not exist. While .html and .php pages are common today, next year .seo pages might be the popular extension.

                SEO - New URL structure

                Hi, Currently we have the following url structure for all pages, regardless of the hierarchy: domain.co.uk/page, such as domain/blog name. Can you, please confirm the following: 1. What is the benefit of organising the pages as a hierarchy, i.e. domain/features/feature-name or domain/industries/industry-name or domain/blog/blog name etc. 2. This will create too many 301s - what is Google's tolerance of redirects? Is it worth for us changing the url structure or would you only recommend to add breadcrumbs? Many thanks Katarina

                Google has deindexed a page it thinks is set to 'noindex', but is in fact still set to 'index'

                A page on our WordPress powered website has had an error message thrown up in GSC to say it is included in the sitemap but set to 'noindex'. The page has also been removed from Google's search results. Page is https://www.onlinemortgageadvisor.co.uk/bad-credit-mortgages/how-to-get-a-mortgage-with-bad-credit/ Looking at the page code, plus using Screaming Frog and Ahrefs crawlers, the page is very clearly still set to 'index'. The SEO plugin we use has not been changed to 'noindex' the page. I have asked for it to be reindexed via GSC but I'm concerned why Google thinks this page was asked to be noindexed. Can anyone help with this one? Has anyone seen this before, been hit with this recently, got any advice...?

                Word mentioned twice in URL? Bad for SEO?

                Is a URL like the one below going to hurt SEO for this page? /healthcare-solutions/healthcare-identity-solutions/laboratory-management.html I like the match the URL and H1s as close as possible but in this case it looks a bit funky. /healthcare-solutions/healthcare-identity-solutions/laboratory-management.html

                JavaScript page loader - SEO impact

                Hello all,
                I am working on a site that has a bizarre page load system. All pages get loaded trough the same Javascript snippet, for example: Changing the values in the form changes the page that is loaded. The most incredible thing is that, against my expectations, pages do get indexed by Google.
                My question is: "Does loading pages dynamically using JavaScript affect the overall SEO performance?" Why are pages getting indexed? Thank you for shedding light on this.
                Cheers
                Luca

                Javascript to manipulate Google's bounce rate and time on site?

                I was referred to this "awesome" solution to high bounce rates. It is suppose to "fix" bounce rates and lower them through this simple script.  When the bounce rate goes way down then rankings dramatically increase (interesting study but not my question). I don't know javascript but simply adding a script to the footer and watch everything fall into place seems a bit iffy to me. Can someone with experience in JS help me by explaining what this script does? I think it manipulates the reporting it does to GA but I'm not sure.  It was supposed to be placed in the footer of the page and then sit back and watch the dollars fly in. 🙂

                How much impact does bad html coding really have on SEO?

                My client has a site that we are trying to optimise. However the code is really pretty bad. There are 205 errors showing when W3C validating. The >title>, , <keywords> tags are appearing twice. There is truly excessive javascript. And everything has been put in tables.</keywords> How much do you think this is really impacting the opportunity to rank? There has been quite a bit of discussion recently along the lines of is on-page SEO impacting anymore. I just want to be sure before I recommend a whole heap of code changes that could cost her a lot - especially if the impact/return could be miniscule. Should it all be cleaned up? Many thanks

                Blocking URL's with specific parameters from Googlebot

                Hi, I've discovered that Googlebot's are voting on products listed on our website and as a result are creating negative ratings by placing votes from 1 to 5 for every product. The voting function is handled using Javascript, as shown below, and the script prevents multiple votes so most products end up with a vote of 1, which translates to "poor". How do I go about using robots.txt to block a URL with specific parameters only? I'm worried that I might end up blocking the whole product listing, which would result in de-listing from Google and the loss of many highly ranked pages. DON'T want to block: http://www.mysite.com/product.php?productid=1234 WANT to block: http://www.mysite.com/product.php?mode=vote&productid=1234&vote=2 Javacript button code: onclick="javascript: document.voteform.submit();" Thanks in advance for any advice given. Regards,
                Asim
