    Hello , I noticed that your On-Page SEO is is missing a few factors, for one you do not use all three H tags in your post, also I notice that you are not using bold or italics properly in your SEO optimization. On-Page SEO means more now than ever since the new Google update: Panda. No longer are backlinks and simply pinging or sending out a RSS feed the key to getting Google PageRank or Alexa Rankings, You now NEED On-Page SEO. So what is good On-Page SEO?First your keyword must appear in the title.Then it must appear in the URL.You have to optimize your keyword and make sure that it has a nice keyword density of 3-5% in your article with relevant LSI (Latent Semantic Indexing). Then you should spread all H1,H2,H3 tags in your article.Your Keyword should appear in your first paragraph and in the last sentence of the page. You should have relevant usage of Bold and italics of your keyword.There should be one internal link to a page on your blog and you should have one image with an alt tag that has your keyword….wait there’s even more Now what if i told you there was a simple WordPress plugin that does all the On-Page SEO, and automatically for you? That’s right AUTOMATICALLY, just watch this 4minute video for more information at.

    tax dec’s can are proof of ownership, along with torrens titles. ( also:homesteads, grants)you just need to update your taxes,and you need to have been the first to file your claim over the property

    check this out
    I completely agree with your examination. Fundamentally, most people would agree with you but would be frightened to convey that they do.

    I was curious if you ever thought of changing the layout of your website? Its very well written; I love what youve got to say. But maybe you could a little more in the way of content so people could connect with it better. Youve got an awful lot of text for only having 1 or 2 pictures. Maybe you could space it out better?

    VNA or PACS-centric Models Lead Enterprise Imaging Plans

    By Diagnostic Imaging Staff | July 12, 2012

    ——————————————————————————–

    Most healthcare providers developing an enterprise imaging strategy are considering a vendor-neutral archive or a PACS enterprise archive solution, according to a new KLAS report.

    The report, Enterprise Imaging 2012: Provider’s Strategies and Insights, found that most providers are in the early stages of forming the strategy that would allow access to images at the right time and place, according to market research firm KLAS.

    (MORE: Dicom Systems to Showcase Vendor-Neutral Archive)

    “Image storage is a necessity, no matter what option is chosen,” said Ben Brown, imaging research director and author of the report. “As providers start to bring in more studies and the studies themselves increase in size, the need for storage will increase. In addition, as a provider explained, images will need to be managed as well as stored.”

    Of the providers interviewed, 27 percent said that a vendor-neutral archive (VNA) would be central to their strategy. This option was selected most often by hospitals with more than 500 beds. A PACS-centric archive solution was selected by 25 percent of providers, most of them facilities with fewer than 500 beds.

    GE and Philips were mentioned most often by those interviewed, and customers said they considered their vendor to be part of the imaging strategy moving forward, particularly for a PACS-centric approach. Fuji also has a strong PACS enterprise archive offering, according to KLAS. Agfa and Merge were most often cited for VNA approaches.
