          I have a change, perhaps temporary, to my web store that I will be making. I am wondering if the code that I will comment out () gets spidered?

            Hi Larry, that was a great question. This is why I love SEOMoz.org, there is always something to learn. I had never thought seriously about this question before, as I web developer I just figured it if I commented out html I didn't have to worry about it being crawled. After reviewing the responses I can see there may be a tad more to it then that.

            Good question, good responses.

              There is a possibility that Google will crawl a link in comments, it's happened before with comments in Javascript. However, it will not have any impact at all from an SEO perspective.

                It means the content between comment tags won't get spidered.

                I'm sorry if I wasn't clear enough on my previous comment.

                    Crawlers ignore comment tags. They do not have any SEO impact.

                      How to get a mobile thumbnail image next to the search result?

                      Hey! I noticed the last few months that a lot of google searches now show an image next to your result when on mobile. i managed to get my listing to show an image before but I made some changes to the image and site and can’t seem to get Google to ahow the new image (or any image). I’ve added the image to schema mark up and still no luck. Wouod ahyone have any advice on how to get the image picked up, or st least help increase the odds? The site is https://tourstoniagarafalls.com and you can see it on search (for me it shows on the bottom of page 1) for the keyword “Niagara Falls tours“. Thanks again!

                      How to fix duplicate content for homepage and index.html

                      Hello, I know this probably gets asked quite a lot but I haven't found a recent post about this in 2018 on Moz Q&A, so I thought I would check in and see what the best route/solution for this issue might be. I'm always really worried about making any (potentially bad/wrong) changes to the site, as it's my livelihood, so I'm hoping someone can point me in the right direction. Moz, SEMRush and several other SEO tools are all reporting that I have duplicate content for my homepage and index.html (same identical page). According to Moz, my homepage (without index.html) has PA 29 and index.html has PA 15. They are both showing Status 200. I read that you can either do a 301 redirect or add rel=canonical I currently have a 301 setup for my http to https page and don't have any rel=canonical added to the site/page. What is the best and safest way to get rid of duplicate content and merge the my non index and index.html homepages together these days? I read that both 301 and canonical pass on link juice but I don't know what the best route for me is given what I said above. Thank you for reading, any input is greatly appreciated!

                      Do you need to include the top menu on every single page of the site in the code?

                      When using     cache:     on google, and clicking on Text-only version, our site has the top menu gibberish on top? My feeling is that this take away SEO juice from our title and focus keyword. Our website is culinarydepotinc.com

                      Getting access to clients websites for onsite seo

                      I understand on site seo fine, as I have tweeked up my own website a fair bit. But I am thinking about doing Onsite and Offsite SEO for clients, as I have had a few request now. So my question is what is the best way to get access to clients websites. So I can make the required adjustments. I have one client, who had a company create a website for him, but they have since closed down.

                      Page title getting cut off in SERPS even though it's under 70 characters?

                      I re-wrote the page title of a home page for a site I'm working on and made sure it's under 70 characters (68 to be exact) to comply with best practices and make sure it doesn't get cut-off in the SERPS.  It's still getting cut-off though and right when it gets to the brand/website name.  Does a "-" have anything to do with it?  Does that translate to an elipsis? Format: keywords - website/brand.com Can anybody tell me why this would be happening?

                      Does Code Order Matter?

                      I read/was told that it was a good idea to order your HTML to show the most important content first. So, on many sites I had put my global navigation div, for instance, below my main content div. Does this still apply? And does wise use of HTML 5 mean this is no longer necessary (eg use of "nav" section tag to indicate this section is about navigation). In the same vein, how does Google know that my sidebar nav is my sidebar nav (which your site seems to say is probably given less weight than top nav), and how does it know my topnav is my top nav? Maybe a daft question, but when someone asked me yesterday I realised I didn't know! (Phew - at last I have asked a short question!).
