      If a page is clearly unique and there is obviously no canonical tag needed, does it hurt anything if one has been added?

        In my opinion, you want the juice for each article to stay with each article.  I wouldn't redirect all your article juice back to the main /blog page.  For me, each unique page (and article) gets its own canonical link and one line = one set of information.  Article about oranges, article about apples, both canonical links.  You should only get juice from same or similar pages, such as

        yoursite.com/

        yoursite.com/index.php

        www.yoursite.com/index.php

        www.yoursite.com/

        But not

        yoursite.com/oranges/

          hey matt, thanks for the response.  let me ask you this.  i have a blog page with a bunch of snippets, that when clicked, lead to the full articles, (each have their own custom page/url).  if i want all the juice to go to the main blog page i don't want to have canonical tags on each individual post page, right?

            Agreed. You page can sometimes end up with query parameters as well when people link to your site, and having the canonical in place will help you avoid having duplicate content.

              It shouldn't hurt you if it doesn't need it but assuming you have www and non-www, wouldn't that part of the canonical always help anyways?  By default, you would have

              http://www.yoursite.com/notagneeded

              http://yoursite.com/notagneeded

              and if you're on most common CMSs,

              http://www.yoursite.com/notagneeded/index.php or index.html or index.asp

              It would actually be pretty rare to have a page with absolutely no use for rel=canonical but I don't see why it would hurt at all.

                Reason for robots.txt file blocking products on category pages?

                Hi I have a website with thosands of products. On the category pages, all the products are linked to with the code “?cgid” in the URL. But “?cgid” is also blocked in the robots.txt file for some reason. So I'm thinking it's stopping all my products getting crawled by Google. Am I right here? Is there any reason why a website would want to limit so many URL's? I'm only here a week and the sites getting great traffic, so don't want to go breaking it!!! Thanks

                My news site not showing in "In the news" list on Google Web Search

                I got a news website (www.tapscape.com) which is 6 years old and has been on Google News since 2012. However, whenever I publish a news article, it never shows up "In the news" list on Google Web Search. I have already added the schema.org/NewsArticle on the website and have checked it if it's working or not on Google structured data testing tool. I see everything shows on on the structured data testing tool. The site already has a news sitemap (http://www.tapscape.com/news-sitemap.xml) and has been added to Google webmaster tools. News articles show perfectly fine in the News tab, but why isn't the articles being shown on "In the news" list on the Google web search? My site has a strong backlink background already, so I don't think I need to work on the backlinks. Please let me know what I'm doing wrong, and how can I get it to the news articles on "In the news" list. Below is a screenshot that I have attached to this question to help you understand what I mean to say. 1qoArRs

                Magento Category H1 Tags

                I am currently using magento and have all titles labeled correctly. I have made a H1 tag for the main page which works fine. Each product title becomes and H1 tag, which again is fine. However my category pages are missing H1 tags. If I manually code an H1 tag, then there becomes 2 H1 tags. It is using my category name then my manual H1 tag. I don't want it to use my category name because it is shortened to fit on my navigation bar.
                Ex. www.mydomain.com/tshirts/short-sleeve 
                In this example the subcategory title is short sleeve. When using MOZ tool on frontend it shows NO H1 tag or the title becomes H1 tag "short sleeve" however I want the H1 to actually be "short sleeve tshirts"
                If I manually add an H1 tag to description on category page it adds both the title AND the H1 tag I enter.

                Reasons Why Our Website Pages Randomly Loads Without Content

                I know this is not a marketing question but this community is very dev savvy so I'm hoping someone can help me. At random times we're finding that our website pages load without the main body content. The header, footer and navigation loads just fine. If you refresh, it's fine but that's not a solution. Happens on Chrome, IE and Firefox, testing with multiple browser versions Happens across various page types - but seems to be only the main content section/container Happens while on the company network, as well as externally Happens after deleting cookies, temporary internet files and restarting computer We are using a CMS that is virtually unheard of - Bridgeline/Iapps Codebase is .net Our IT/Dev group keeps pushing back, blaming it on cookies or Chrome plugins because they apparently are unable to "recreate the problem". This has been going on for months and it's a terrible experience for the user to have. It's also not great when landing PPC visitors on pages that load with no content. If anyone has ideas as to why this may be happening I would really appreciate it. I'm not sure if links are allowed, by today the issue happened on this page serversdirect.com/dm/geek-biz Linking to an image example below knEUzqd

                One Page Guide vs. Multiple Individual Pages

                Howdy, Mozzers! I am having a battle with my inner-self regarding how to structure a resources section for our website. We're building out several pieces of content that are meant to be educational for our clients and I'm having trouble deciding how to layout the content structure. We could either layout all eight short sections on a single page, or create individual pages for each section. The goal is obviously to attract new potential clients by targeting these terms that they may be searching for in an information gathering stage. Here's my dilemma...
                With the single page guide, it would be nice because it will have a lot of content (and of course, keywords) to be picked up by the SERPS but I worry that it is going to be a bit crammed (because of eight sections) for the user. The individual pages would be much better organized and you can target more specific keywords, but I worry that it may get flagged for light content as some pages may have as little as a 150 word description. I have always been mindful of writing copy for searchers over spiders, but now I'm at a more technical crossroads as far as potentially getting dinged for not having robust content on each page. Here's where you come in...
                What do you think is the better of the two options? I like the idea of having the multiple pages because of the ability to hone-in on a keyword and the clean, organized feel, but I worry about the lack of content (and possibly losing out on long-tail opportunities). I'd love to hear your thoughts. Please and thank you. Ready annnnnnnnnnnnd GO!

                Need to rebuild client's flash website

                I am working with their web designer and need to figure out a way to rebuild their site which is currently all in flash. I was wondering if there was a way to do this without spending a ton of time in completely re-doing the site from scratch.

                Footer backlinks for sites I've developed

                I link back to my website via my company name on the footers of sites I develop.  Lately I've been changing this to my keyword and mixing and matching.  This has been done for new sites I create and old sites I've not seen any benefit so far after a couple of months. Most my clients are hosted on the same server as my main site that it links back to. 1. Is this a bad idea to link back on the same IP?
                2. Is footer backlinks to the main developer going to annoy Google?
                3. Should I change my main site's server, will it help? All my competitors seem to do it and as far as I can tell they seem to get better results than I do.  Because I'm now changing them the reason I see no benefit? Thanks

                Combining web pages and it's affects on SEO?

                We are looking into amending a website we are working on to try and combine 2 or 3 current pages onto one page. This site is similar to an estate agents site and currently has images, map, floor plan sub pages etc. Can anyone tell me, if we were to combine these pages and include the above details on one page, how that would affect the current search engine rankings?
