      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.

                Spam URL'S in search results

                We built a new website for a client. When I do 'site:clientswebsite.com' in Google it shows some of the real, recently submitted pages. But it also shows many pages of spam url results, like this 'clientswebsite.com/gockumamaso/22753.htm' - all of which then go to the sites 404 page. They have page titles and meta descriptions in Chinese or Japanese too. Some of the urls are of real pages, and link to the correct page, despite having the same Chinese page titles and descriptions in the SERPS. When I went to remove all the spammy urls in Search Console (it only allowed me to temporarily hide them), a whole load of new ones popped up in the SERPS after a day or two. The site files itself are all fine, with no errors in the server logs. All the usual stuff...robots.txt, sitemap etc seems ok and the proper pages have all been requested for indexing and are slowly appearing.  The spammy ones continue though. What is going on and how can I fix it?

                Strange URL's for client's site

                We just picked up a new client and I've been doing some digging around on their site. They have quite the wide variety of URL's that make for a rather confusing experience. One of the milder examples is their "About" page. Normally I would expect something along the lines of: www.website.com/about I see: www.website.com/default.asp?Page=About I'm typically a graphic designer and know basically nothing about code, but I just assume this has something funky to do with how their website was constructed. I'm assuming this isn't particularly SEO friendly, but it doesn't seem too bad. Until I got to another section of their site. It's a section that logically should look like: www.website.com/training/public-seminars It's: www.website.com/default.asp?Page=MT&Area=Seminars&Sub=MRM Now that's nonsensical to me! Normally if a client has terrible URL's, I'd say let's do some redirects, but I guess I'm a little intimidated by these. Do the URL's have to be structured like this for some reason? Am I missing some important area of coding here? However, the most bizarre example is a link back to their website from yellowpages.com. Where normally I would expect it to lead to their homepage, I get this bizarre-looking thing: http://website1-px.rtrk.com/?utm_source=ReachLocal&utm_medium=PPC&utm_campaign=AssetManagement&reference_id=15&publisher=yellowpages&placement=ypwebsitemip&action_target=listing_website And as you browse through the site, that strange domain stays. For example the About page is now: http://website1-px.rtrk.com/default.asp?Page=About I would try to google this but I have no idea where to even start! What is going on with these links? Will we be able to fix them to something presentable without breaking their website?

                Domain prefix changed, will this impact SEO?

                Our web development team have changed our domain prefix from www to non www due to a server change. Our SSL certificate would not be recognised under www and would produce a substantial error message when visiting the secure parts of our website. To prevent issues with old links they have added a permanent 301 redirect from www. to non www. urls until our sitemap catches up. Would this impact our SEO efforts or would it have no impact as a redirect has been placed? Thanks

                SEO impact of the anatomy of URL subdirectory structure?

                I've been pushing hard to get our Americas site (DA 34) integrated with our higher domain authority (DA 51) international website. Currently our international website is setup in the following format... website.com/us-en/ website.com/fr-fr/ etc... The problem that I am facing is that I need my development framework installed in it's own directory. It cannot be at the root of the website (website.com) since that is where the other websites (us-en, fr-fr, etc.) are being generated from. Though we will have control of /us-en/ after the integration I cannot use that as the website main directory since the americas website is going to be designed for scalability (eventually adopting all regions and languages) so it cannot be region specific. What we're looking at is website.com/[base]/us-en. I'm afraid that if base has any length to it in terms of characters it is going to dilute the SEO value of whatever comes after it in the URL (website.com/[base]/us-en/store/product-name.html). Any recommendations?

                Should I noindex my blog's tag, category, and author pages

                Hi there, Is it a good idea to no index tag, category, and author pages on blogs? The tag pages sometimes have duplicate content.  And the category and author pages aren't really optimized for any search term. Just curious what others think. Thanks!

                Is it good practice to still pay for Best of the Web Directory (BOTW) and other similar one's you have to pay for?

                I know that paid for links are hit by Google, but in the past these directories were okay. What about now? Thank you.

                Correct linking to the /index of a site and subfolders: what's the best practice? link to: domain.com/ or domain.com/index.html ?

                Dear all, starting with my .htaccess file: RewriteEngine On
                RewriteCond %{HTTP_HOST} ^www.inlinear.com$ [NC]
                RewriteRule ^(.*)$ http://inlinear.com/$1 [R=301,L] RewriteCond %{THE_REQUEST} ^./index.html 
                RewriteRule ^(.)index.html$ http://inlinear.com/ [R=301,L] 1. I redirect all URL-requests with www. to the non www-version...
                2. all requests with "index.html" will be redirected to "domain.com/" My questions are: A) When linking from a page to my frontpage (home) the best practice is?: "http://domain.com/" the best and NOT: "http://domain.com/index.php" B) When linking to the index of a subfolder "http://domain.com/products/index.php" I should link also to: "http://domain.com/products/" and not put also the index.php..., right? C) When I define the canonical ULR, should I also define it just: "http://domain.com/products/" or in this case I should link to the definite file: "http://domain.com/products**/index.php**" Is A) B) the best practice? and C) ? Thanks for all replies! 🙂

                Are Collapsible DIV's SEO-Friendly?

                When I have a long article about a single topic with sub-topics I can make it user friendlier when I limit the text and hide text just showing the next headlines, by using expandable-collapsible div's. My doubt is if Google is really able to read onclick textlinks (with javaScript) or if it could be "seen" as hidden text? I think I read in the SEOmoz Users Guide, that all javaScript "manipulated" contend will not be crawled. So from SEOmoz's Point of View I should better make use of old school named anchors and a side-navigation to jump to the sub-topics? (I had a similar question in my post before, but I did not use the perfect terms to describe what I really wanted. Also my text is not too long (<1000 Words) that I should use pagination with rel="next" and rel="prev" attributes.) THANKS for every answer 🙂
