      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.

                  When Google rewrites a title tag, do you get the SEO impact for the original version?

                  title tags on page optimization on-page meta data meta tags

                  Let's say you're writing a homepage title tag like this: KEYWORD | BRAND and Google rewrites it as BRAND | KEYWORD From Moz and best practices, we believe that keywords closer to the beginning of a title tag may have more impact on search rankings. So, when Google rewrites the title tag, do you get the impact you would have made with the keyword being closer to the front? Or, does Google give you the impact you would have received with the keyword being at the end?

                  400-499 http status code

                  Hi there, I noticed in Bing Webmaster Tools that we get the following for the home page.These pages have 400-499 http status code. Ensuring http status 200 might help improve SERP performance and gain user traffic.I haven't seen this before, nothing comes up in Moz or Google Webmaster Tools about it.Is it worth spending time on resolving the issue, I don't see how it affects us as the page loads up perfectly but I don't understand the error.The error shows up for our home page, https : // wwww domainname comWhen checking here we get green ticks for everything sslshopper.com/ssl-checker.html

                  Does anyone know of a tool where you can get all of the keyword that any given landing page is ranking for?

                  I'd like to find out what landing pages are ranking for which keywords, but I haven't been able to find a tool that does it. I was hoping there would be something where I could submit the url and get a list of every keyword it is ranking for. Any thoughts or suggestions? Thanks!

                  Does blogging with a wysiwyg negatively affect SEO (vs. hand coding)?

                  Many bloggers use a wysiwyg editor to write posts. Are there any drawbacks to wysiwyg vs plain text? When I write blogs I prefer to hand code my text to be sure everything is optimized. My feeling is that wysiwyg leads to code bloat and generally fewer optimization opportunities. I have no real evidence. Is there any reason not to use the wysiwyg editor?

                  HTML Site SEO (NO CMS)

                  I have got a client site, which is dated (2007) and has not been shifted to any recognised CMS yet. It is HTML based. Is it possible to SEO on such a site? Is it even worth it? If it is possible to do SEO on this, any suggestions will be highly appreciated. Thank you.

                  Does 'XXX' in Domain get filtered by Google

                  I have a friend that has xxx in there domain and they are a religious based sex/porn addiction company but they don't show up for the queries that they are optimized against. They have a 12+ year old domain, all good health signs in quality links and press from trusted companies. Google sends them adult traffic, mostly 'trolls' and not the users they are looking for. Has anyone experienced domain word filtering and have a work around or solution? I posted in the Google Webmaster help forums and that community seems a little 'high on their horses' and are trying to hard to be cool. I am not too religious and don't necessarily support the views of the website but just trying to help a friend of a friend with a topic that I have never encountered. here is the url: xxxchurch.com Thanks, Brian

                  No follow for html sitemap?

                  Hi, I have been working on an e-commerce site and have been wondering if i should add the meta robot tag with no follows, on pages like delivery , terms, returns and the html sitemap? From what I have read this seems a good idea, but i am a little confused as what to do with the html sitemap. I can understand that having this on the homepage will allow crawlers quick access to the deeper pages within the site. But would it be better to guide them down the natural route of the category navigation instead? Thanks
