          On our website we have some invisible/hidden categories on our site. Can anyone advise whether these are harmful in terms of SEO?

            You could legitimately have hidden content in terms of category/URLs - maybe only made available if you sign up as an example.  The guidelines are referring to manipulating on page content so there are elements within that page that are hidden and by default manipulating.

              Firstly I cannot actually think of any legitimate reason for hiding or making a category invisible, however if you had one that means you don’t want the content to be indexed then you would be best blocking that Category within your robots.txt file.

              If it is for any other reason and the content is indexable by ANY search engine not just Google then you run the risk of being penalised.

              In fact, Google’s guidelines state that, “hiding text or links in your content to manipulate Google’s search rankings can be seen as deceptive and is a violation of Google’s Webmaster Guidelines

                Invisible to who?  If they are invisible to the search engines (e.g. blocked via robots.txt) they could not be harmful, but if you gain any link or other quality equity through those pages, your will not get any additional domain authority or organic traffic to them.

                That said, if the hidden categories were resorts of the main categories on your site then you would want to hide them from the search engine as they would be seen as low quality duplicate content.  Otherwise if they were visible they could negatively impact your site.

                  Yoast SEO doesn't recognize images

                  Hi, I'm currently adding alt tags to my images but the Yoast SEO plug in in Wordpress states on all my pages “No images appear in this page, consider adding some as appropriate.“ while I do have images on my pages. What could be the problem? Best, Rik

                  Do Blog Tags affect SEO at all anymore?

                  We're trying to standardize the use of tags on our site amongst writers/editors, and I'm trying to come up a list of tags they can choose from to tag posts with - and telling them to use no more than 10 (absolute maximum) per post. We are also in the process of migrating to a new CMS, and have 8 defined categories that will all have their own landing page within our "News" section. TLDR: Do blog tags have any impact on SEO anymore? Are they solely meant to help users find articles related on popular topics, or does creating a tag for a popular topic help to improve organic visibility? Full Question: With the tag standardization, I want to make sure we're creating the most useful and effective tags; and the UX/SEO sides of my brain are conflicted. To my understanding, creating a tag about a high volume topic in an industry helps establish the website's relevance to Google/other search engines about that topic and improves overall relevance; but the tag feed page (ex: http://freshome.com/tag/home-protection/) isn't really meant for organic search visibility. So my other question is, is it worth it to noindex the tag pages in the robots.txt? Will that affect any benefit to increased relevance for Google (if there is any)? I'm interested to hear others' thoughts and suggestions. Thanks in advance!

                  URL Path. What is better for SEO

                  Hello Moz people, Is it better for SEO to have a URL path like this: flowersite.com/anniversary_flowers/dozen_roses OR flowersite.com/dozen_roses Is it better to have the full trail of pages in the URL?

                  ECommerce Filtering Affect on SEO

                  I'm building an eCommerce website which has an advanced filter on the left hand side of the category pages. It allows users to tick boxes for colours, sizes, materials, and so on. When they've made their choices they submit (this will likely be an AJAX thing in a future release, but isn't at time of writing). The new filtered page has a new URL, which is made up of the IDs of the filter's they've ticked - it's a bit like /department/2/17-7-4/10/ My concern is that the filtered pages are, on the most part, going to be the same as the parent. Which may lead to duplicate content. My other concern is that these two URLs would lead to the exact same page (although the system would never generate the 'wrong' URL) /department/2/17-7-4/10/ /department/2/**10/**17-7-4/ But I can't think of a way of canonicalising that automatically. Tricky. So the meat of the question is this: should I worry about this causing issues with the SEO - or can I have trust in Google to work it out?

                  Trying to SEO a site that used Header Tags for Design

                  I am trying to SEO a website that was built years ago and uses Header tags for design.  The site must have 25 and tags used for design purpose. Is there any way to work around this problem?  Perhaps a code that tells Google to ignore these as Headers?  The web designers say that they are looking to fix the problem sometime this summer but you never know if that means it a month away or years away.  I really want to help this website but I believe that the Header tags are one of the reasons that his site does not show in the top 100  rankings for any keywords.  Any help would be great. www.wallybuysell.com Chris.K

                  SEO for luxury brands!?

                  Hi all, It is widely known fact that you will be a bit in trouble if you will need to do SEO for luxury brand that is not willing to sacrifice design, layout etc. for SEO purposes. So basically - there is no content to optimize and there is almost no keywords to rank! 😉 Just wondering - how would be the best to approach such kind of terrible situation? Regards, Jungle

                  How to avoid keyword stuffing on e-Commerce Category pages

                  Hi, I'm optimizing a large, consumer electronic e-commerce superstore. Based on client's choice of keywords, I'm using product category pages as my target urls. Because of the proprietary CMS structure, product names and titles, featured on my landing pages (product category pages) create a keyword overkill, affecting various ranking factors. For example, one of the target urls / landing pages, dedicated to a specific product category, mentions the keyword over 190 times because of so many product titles in the "body" section. Would inline "rel="canonical" help? If yes, what part of the website should it "canonize"? If rel="canonical" is not the answer, what strategies would you suggest? Thanks!
