      Is it better to use a dash or an underscore in file names to improve SEO? EX memory_flash.jpg or memory-flash.jpg

      Or does it make no difference?

        In the end it wouldn't matter that much but I would also prefer using dashes as well.

          Use dashes. Underscores don't specify any specific function whereas dashes are specifically word separators.

            Url shows up in "Inurl' but not when using time parameters

            Hey everybody, I have been testing the Inurl: feature of Google to try and gauge how long ago Google indexed our page. SO, this brings my question. If we run inurl:https://mysite.com all of our domains show up. If we run inurl:https://mysite.com/specialpage the domain shows up as being indexed If I use the "&as_qdr=y15" string to the URL, https://mysite.com/specialpage does not show up. Does anybody have any experience with this? Also on the same note when I look at how many pages Google has indexed it is about half of the pages we see on our backend/sitemap. Any thoughts would be appreciated. TY!

            Does using Yoast variables for meta content overwrite any pages that already have custom meta content?

            The question is about the Yoast plugin for WP sites. Let's say I have a site with 200 pages and custom meta descriptions / title tags already in place for the top 30 pages. If I use the Yoast variable tool to complete meta content for the remaining pages (and make my Moz issue tracker look happier), will that only affect the pages without custom meta descriptions or will it overwrite even the pages with the custom meta content that I want? In this situation, I do want to keep the meta content that is already in place on select pages. Thanks! Zack

            Hi guys, I have a client who wants to use a hyphen to separate two words in the URL to make each work stand out. Is is good or bad practice to use a hyphen in a URL and will it affect rankings? Thanks!

            Solve duplicate content issues by using robots.txt

            Hi, I have a primary website and beside that I also have some secondary websites with have same contents with primary website. This lead to duplicate content errors. Because of having many URL duplicate contents, so I want to use the robots.txt file to prevent google index the secondary websites to fix the duplicate content issue. Is it ok? Thank for any help!

            Duplicate Content when Using "visibility classes" in responsive design layouts? - a SEO-Problem?

            I have text in the right column of my responsive layout which will show up below the the principal content on small devices. To do this I use visibility classes for DIVs. So I have a DIV with with a unique style text that is visible only on large screen sizes. I copied the same text into another div which shows only up only on small devices while the other div will be hidden in this moment. Technically I have the same text twice on my page. So this might be duplicate content detected as SPAM? I'm concerned because hidden text on page via expand-collapsable textblocks will be read by bots and in my case they will detect it twice?Does anybody have experiences on this issue?bestHolger

            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

            Is it ok to use the H1 tag for bullet points?

            Our search results page doesn't have a typical H1 tag because adding a true header would take up space unnecessarily. Therefore, we've assigned the h1 tag to be the breadcrumb. As filters are applied, the breadcrumb grows to include these filters. This breadcrumb is coded as bullet points, even though they're not the typical style of bullet points. Here's a screenshot: http://screencast.com/t/AjGC9iAYR3 For example, the breadcrumb: Home >> NYC Social Media Classes >> Adult >> Manhattan is currently coded as: | |
            |   | * class="first"><a <span="">href</a><a <span="">="</a>/">Home |
            |   | * <a <span="">href</a><a <span="">="</a>/nyc/classes/social-media/age-adults/neighborhood-manhattan" class="Selected">Search results |
            |   | |
            |   | |
            |   | id="cat_social-media" type="checkbox" checked onclick="setCategory('social-media')" /> |
            |   | # style="font-size: 12px; display: inline;">NYC Social Media Classes |
            |   | <label <span="">for</label>="cat_social-media"> |
            |   | |
            |   | |
            |   | |
            |   | <nobr>id="age_adults" type="checkbox" checked onclick="setAge('adults')" /><label <span="">for</label>="age_adults">Adults</nobr> |
            |   | |
            |   | |
            |   | <nobr>id="nbhd_manhattan" type="checkbox" checked onclick="setNeighborhood('manhattan')" /><label <span="">for</label>="nbhd_manhattan">Manhattan</nobr> |
            |   | |
            |   | | Right now that H1 tag just relates to 'NYC Social media classes', but we'd like to expand it to include both 'Manhattan' & 'Adults' - would that be ok? And if so, would it be better to put the tag before and after the tag?
