      Hi all,

      I'm very new to SEO and still learning a lot.

      Is it considered a black hat tactic to wrap a link in a DIV tag, with display set to none (hidden div), and what can the repercussions be?

      From what I've learnt so far, is that this is a very unethical thing to be doing, and that the site hosting these links can end up being removed from Google/Bing/etc indexes completely. Is this true?

      The site hosting these links is a group/parent site for a brand, and each hidden link points to one of the child sites (similar sites, but different companies in different areas).

      Thanks in advance!

        Thanks for the quick feedback. 
        This clears up things for me a bit.

          The separation between black hat and white hat tactics is generally a clear line. The simple question is, does the code exist for the benefit of your site's visitors or solely to manipulate search engines?

          DIV tags are used to apply CSS rules to specific pieces of code. If you have a link contained in a DIV and the display set to none, that link would clearly never be seen by the site's visitors. It is apparent the link exists solely to manipulate search engine results, and therefore is a black hat tactic.

          When Google and other search engines discover black hat tactics being used on a site, they will take action. The action can be relatively minor such as ignoring the link. The action could be mid-range such as removing the page containing the link from the index. At the extreme end, they can remove the entire site from the index.

          Each search engine has their own internal guidelines on how to handle these issues. Some issues are handled automatically via algorithms, while other issues are handled by manual review. There are no published standards on exactly which punishments will be handed out for a given violation. It is simply best to completely avoid anything black hat.

            How can I stop a tracking link from being indexed while still passing link equity?

            I have a marketing campaign landing page and it uses a tracking URL to track clicks. The tracking links look something like this: http://this-is-the-origin-url.com/clkn/http/destination-url.com/ The problem is that Google is indexing these links as pages in the SERPs. Of course when they get indexed and then clicked, they show a 400 error because the /clkn/ link doesn't represent an actual page with content on it. The tracking link is set up to instantly 301 redirect to http://destination-url.com. Right now my dev team has blocked these links from crawlers by adding   Disallow: /clkn/   in the robots.txt file, however, this blocks the flow of link equity to the destination page. How can I stop these links from being indexed without blocking the flow of link equity to the destination URL?

            Is there a limit to how many URLs you can put in a robots.txt file?

            We have a site that has way too many urls caused by our crawlable faceted navigation.  We are trying to purge 90% of our urls from the indexes.  We put no index tags on the url combinations that we do no want indexed anymore, but it is taking google way too long to find the no index tags.  Meanwhile we are getting hit with excessive url warnings and have been it by Panda. Would it help speed the process of purging urls if we added the urls to the robots.txt file?  Could this cause any issues for us?  Could it have the opposite effect and block the crawler from finding the urls, but not purge them from the index? The list could be in excess of 100MM urls.

            Is it ok to use H1 tags in breadcrumbs?

            A client has an e-commerce site and she doesn't want a page title on the products page. She has breadcrumbs though. Her website developer suggests putting the H1 on the breadcrumbs. So: products> Gifts > picture frame with h1 tags round the word "picture frame". Is this ok to do? Or is it a bad thing for SEO purposes? Thanks

            Can I mark up breadcrumbs without showing them? (responsive design)

            I am working on a site that has responsive design. We use faceted search for the desktop version but implemented a style of breadcrumbs for the mobile version as sidebars take up too much screen real estate. On the desktop design we are putting a display:none in front of the breadcrumbs. If we mark up those breadcrumbs and they are behind a display none, can we still get the rich snippets? Will Google see this is cloaking? In follow up, is there a way to markup breadcrumbs in the or somewhere else that is constant?

As open site explorer or Google still shows these links on the searches. Should we mention these URL's in disallow in Google webmaster. Thanks

            How valuable is content "hidden" behind a JavaScript dropdown really?

            I've come across a method implemented by some SEO agencies to fill up pages with somehow relevant text and hide it behind a javascript dropdown. Does Google fall for such cheap tricks? You can see this method used on these pages for example (just scroll down to the bottom) - it's all in German, but you get the idea I guess: http://www.insider-boersenbrief.de/ http://www.deko-und-kerzenshop.de/ How is you experience with this way of adding content to a site? Do you think it is valuable or will it get penalised?

            What can I do about missing Meta Description for category pagest etc.?

            On all my campaigns I'm returning high levels of 'Missing Meta Description Tags'. The problem with fixing this is they're all for category, tag and author pages. Is there a way to add a meta description to these pages (there are hundreds) or will it not really have any ranking effect?
