          Hi,

          I'm currently working with a developer who is trying to tell me that validation errors and warnings are of little to no importance in a website's SERP.

          In the past, whenever I've had a site that was experiencing problems ranking for a keyword terms, this was one of the first places we'd look.

          Is this still a relatively important component in getting a site to rank?

            Absolutely! I will dig into this tonight and give you my honest feedback. Something I did notice that I would make a top priority is the load time of the page/site.

            Upon opening the page, I noticed it took a quite a bit to load. After running through Pingdom & Page Speed Insights (links below), I'd make the load time fixes a top priority for your developer.

            Pingdom Test Results

            Google Page Speed Insights

            I would jump all over these first and foremost but I will look through the html errors tonight and get back to you!

              Bryan,

              I'm going to give you an example of one of the site pages after I run it through W3C validator. Would you mind having a look at it and telling me how highly I should prioritize fixing these issues?

              http://validator.w3.org/check?uri=http%3A%2F%2Fwww.lawtonmd.com%2Fprocedures%2Fbreasts%2Faugmentation&charset=%28detect+automatically%29&doctype=Inline&group=0

              The developer I'm working with on this site is telling me that these issues are a very low priority, but as I'm seeing throughout the threads, his lack of interest in repairing these issues is of some concern to me.

                  What Egol said is quite true...this has been debated for years....but those of us who don't care about the validations rank our own or our clients sites quite nicely.

                  Oh sidebar - you'd be so surprised to learn what kind of HUGE well known sites won't validate either....

                      Indeed! I'd be more concerned as a developer that there are glitches even if it won't affect SEO. Bad business

                        I would worry more about Google guidelines and best practices rather than wasting time on W3C validation.

                          A developer who tells you "W3C validation isn't important" is like a house builder telling you "Those small cracks in the walls are nothing to worry about"

                            I will totally agree with EGOL's idea. If the website speed time is fine you don't really have to go for all the non important code ethics and everything.

                              Seconding EGOL's statement, for the most part.

                              Years ago, The Matt Cutts stated W3C valid code wasn't a ranking factor. There's been a bit of debate over the years, but there still isn't much evidence to support W3C validation itself as a ranking factor. So it's something you probably can put on the back burner for more pressing concerns.

                              Honestly, sometimes errors are flagged simply because a comment or two are a little wonky. But that won't really inhibit how competitive a site is. If the site has 'quite a few' errors and warnings, that could potentially decrease site speed. Site speed is a ranking factor.

                              I suppose my best answer is; "No, it's not a ranking factor itself. Though there's some potential for poor coding to harm something that is a ranking factor."

                                It depends who you ask.

                                If you ask one of the W3C evangelists they will tell you that you will never get good rankings without it and that google will penalize your website and not allow it to be seen in certain countries.

                                If you ask people who really know about this stuff they will tell you that if your site renders well in most browsers you will do fine in search.

                                  Hello

                                  While there are good reasons to validate your code, it does not directly affect your rankings. Matt Cutts talks about this in a video: https://www.youtube.com/watch?v=FPBACTS-tyg

                                  Validation does give insight into your development needs and will help you to improve user experience. However broken code won't take away from good content and that is primarily what search engines are looking for.

                                    Hey luckybluebox!

                                    IMO, this is rather important aspect of proper development and we make sure every site we work on is W3C compliant. These are typically easy fixes and should always be cleaned up.

                                    Check out this youtube video from Google Webmasters channel. They say it is NOT a ranking factor but I would always suggest keeping things tidy 😃

                                    Hope this helps you out!!! https://www.youtube.com/watch?v=2XlKn6I9rSc

                                        Do you think profanity in the content can harm a site's rankings?

                                        In my early 20's I authored an ebook that provides men with natural ways to improve their ahem... "bedroom performance". I'm now in my mid 30s, and while it's not such an enthralling topic, the thing makes me 80 or so bucks a day on good days, and it actually works. I update the blog from time to time and build links to it on occasion from good sources. I've carried my SEO knowledge to a more "reputable" business, but this project is still interesting to me, because it's fully mine. I am more interested in getting it to rank and convert than anything, but following the same techniques that are working to grow the other business, this one continues to tank. Disavow bad links, prune thin content.. no difference. However, one thing I just noticed now are my search queries in the reports. When I first started blogging on this, I was real loose with my tongue, and spoke quite frankly (and dirty to various degrees). I'm much more refined and professional in how I write now. However, the queries I'm ranking for... a lot of d words, c words (in the sex sense)... sounds almost pornographic. Think Google may be seeing this, and putting me lower in rankings or in some sort of lower level category because of it? Heard anything about google penalizing for profanity? I guess in this time of authority and trust, that can hurt both of those... but I wonder if anyone's heard any actual confirmation of this or has any experience with this? Thanks!

                                        Are Meta-descriptions important for blogs?

                                        I am tasked with optimizing an existing sites SEO. I have added meta's to all the menu pages, however they have blog section with over 700 posts. How important are meta descriptions when it comes to a websites blog? Do I need to take the time to go through 700+ blog posts and create unique meta descriptions for each one?

                                        Log-in page ranking instead of homepage due to high traffic on login page! How to avoid?

                                        Hi all, Our log-in page is ranking in SERP instead of homepage and some times both pages rank for the primary keyword we targeted. We have even dropped. I am looking for a solution for this. Three points here to consider is: Our log-in page is the most visited page and landing page on the website. Even there is the primary keyword in this page or not; same scenario continues Log-in page is the first link bots touch when they crawling any page of our website as log-in page is linked on top navigation menu If we move login page to sub-domain, will it works? I am worrying that we loose so much traffic to our website which will be taken away from log-in page sub domain Please guide with your valuable suggestions. Thanks

                                        Can 'Jump link'/'Anchor tag' urls rank in Google for keywords?

                                        E.g. www.website.com/page/#keyword-anchor-text Where the part after the # is a section of the page you can jump to, and the title of that section is a secondary keyword you want the page to rank for?

                                        Dramatic drop in SEO rankings after recovering from hacking

                                        A few months ago my client's website was hacked which created over 20,000+ spammy links on the site. I dealt with removing the malware and got google to remove the malware warning shortly within a week of the hacking. Then started the long process to do 301 redirects and disavowing links under Webmaster tools over these few months. The hacking only caused a slight drop in rankings at the time. Now just as of last week the site had a dramatic drop in rankings. When doing a keyword search I noticed the homepage doesn't even get listed on Google Maps and for Google Search instead the inner pages like the Contact Us page show up instead of the homepage. Does anyone have any insight to the sudden drop happening now and why the inner pages are ranking higher than the homepage now?

                                        Dates appear before home page description in the SERPs- HUGE drop in rankings

                                        We have been on the first page of Google for a number of years for search terms including 'SEO Agency', 'SEO Agency London' etc. A few months ago we made some changes to the design of the home page (added a blog feed), and made changes to the website sitemap. Two days ago (two months after last site changes were made) we dropped subsantially in the SERPs for all home page keywords. Where we are found, a date appears before the description in the SERPs, dating February 2012 (which is when we launched the original website). The site has been through a revamp since then, yet it still shows 2012. This has been followed by a few additional strange things, including the sitelinks that Google is choosing to show (which including author bio pages showing in homepage site links), and googling our brand name no longer brings up sitelinks in the SERPs. The problem only affects the home page. All other pages are performing as standard. When Penguin 4.0 came out we saw a noted improvement in our SERP performance, and our backlinks are good and quality, largely from PR efforts. Of course, I would be interested in additional pairs of eyes on the back links to see if anyone thinks that I have missed anything! We have 3 of our senior SEOs working on trying to figure out what is going on and how to resolve it, but I would be very interested if anyone has any thoughts?

                                        Is there a way to pull historical rankings for a keyword?

                                        I have someone who's come to me and said that they have lost all of their organic keyword rankings.  They did launch a site redesign a few months back so that could be a reason as to why.  But after looking at the site, link profile, etc.  It doesn't look like they could have been ranking for the terms they say they were.  They have never implemented any SEO on their sites btw.  I did not build this site and have not done any SEO, they are coming to me to solve the problem.  I did notice in SEM rush that a couple months ago they were ranking organically for more terms (20 in July vs. 5 now), so they did lose some.  Is there any way to see what terms they WERE ranking for?

                                        Importance of Product Review Syndication?

                                        Greetings everyone I have been tasked to do research on just how important it is to have product reviews syndicated with Google's (star rating found in Google Shopping). I am unable to find any research reports or studies on this nor any quantitative data on it's impact, beneficial or otherwise. If any of you folks have any first hand experiences, perhaps some before and after figures, that would be great. Thanks
