      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.

            SVG image files causing multiple title tags on page - SEO issue?

            Does anyone have any experience with SVG image files and on-page SEO? A client is using them and it seems they use the title tag in the same way a regular image (JPG/PNG) would use an image ALT tag. I'm concerned that search engines will see the multiple title tags on the page and that this will cause SEO issues. Regular crawlers like Moz flag it as a second title tag, however it's outside the header and in a SVG wrap so the crawlers really should understand that this is a SVG title rather than a second page title. But is this the case? If anyone has experience with this, I'd love to hear about it.

            Using Escaped Fragments with SEO

            Our e-commerce platform is in the process of changing to what we call app based stores (essentially running in a browser as single page web-app)  With these new stores they are being built in HTML 5 and using escaped fragments.
            Currently merchants are usually running 2 stores until we launch to app site at 100%.  My questions are really concerning the app stores which right now show on a subdomain but will essentially take over the primary domain.   Here is an example:
            app.tikimater.com and app.sportsworld.com Since I am not a developer, I'm really having a hard time understanding the escaped fragments. I'm using this but https://developers.google.com/webmasters/ajax-crawling/docs/getting-started I'm not sure what my actual urls should look like and what the canonical should be set to. Right now they have been removed but previously they had  http:app.tikimaster.com#!v=1  Also, and how I should be setting up my meta information for Google so 1) pages are indexed timely 2) pages are indexed with the correct information.  I am still setting the meta titles and descriptions but in some instances Google uses other info. With the new platform we are moving away from on page content (written paragraphs) but category pages would have related products embedded.  Should I still be pushing to have some type of intro text, since it would solely be for SEO and not the shoppers experience. All product pages have content (product description etc) Thank you for any advice

            The company brand name does not show in SERP

            Our company is ranking no.1 for brand keyword, however, when you try to find it by two words(with space between) then all those shows up and the website is nowhere to find. Any suggestions on how to solve this without the need to be ranked for something related

            URL Domain Used in Meta Description

            Today I was asked if using a domain url in your meta description can have a negative impact on your website. This description includes a list of the homepage url, but directs visitors to a different internal page of the website. My concern fell with directing visitors to a different page of the site, but promoting the homepage in the description/snippet. With Penguin 2.1 release on the 4th, I'm very cautious of my links/urls. What are your thoughts behind this? What are the possible, if any negative impacts this could have on a site? This URL does have a brand name as so the Title.

            How to use canonical with mobile site to main site

            I am pretty sure that the mobile version of the main site needs to be the same canonical link from what I understand. I am trying to find good docuementation that supports this. Even better if its from Google or Matt Cutts. I have a main domain like http://www.mydomain.com the mobile version of this is http://www.mydomain.com/m/ Should my canonical be rel="canonical" href="http://www.mydomain.com"/> for both these pages?

            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?

            Post Title - Use the blog's name or not?

            In the tile of my post, shoudl I used my blog's name in it at the end or emit the blog name. EX: title of post with keywords | name of blog OR EX: title of post with keywords The site's name is 3 words long, so I'm worrying that those extra words are diluting the keywords in the post's name that I'm trying to target.
