Comment booster ses campagnes SEM grâce à l’étude du comportement de ses prospects ? Avez-vous déjà pensé à étudier le comportement de vos prospects amenés par vos campagnes SEM en fonction du moment de la journée ? Si ce n’est pas le cas, je vous conseille de le faire, vous pourriez avoir de bonnes surprises en optimisant ces dernières grâce à ces données. Voici une méthode étape par étape… Etape 1 : étudier les performances des campagnes selon les heures de la journée… 1.1 : Exporter les données depuis votre outil de statistiques… La première chose à faire va être de repérer les heures où vos campagnes transforment particulièrement bien. Rendez-vous dans votre outil de statistiques, je vais prendre Google Analytics comme exemple mais la démarche est similaire avec les autres outils (AT Internet…).

Sélectionnez ensuite une période d’analyse assez longue, les trois derniers mois par exemple. 1.2 : Affiner l’analyse via Excel… Pour conclure…

SEO Is Dead. Audience Optimization Is Taking Its Place If you've ever tried to deal with search engine optimization, you most likely have, at some point or another, wanted to bundle your whole site up and toss it into the nearest virtual trash can. Particularly if you felt compelled to focus on keywords, or any other technique calculated to artificially pique someone's mouse clicks. You should be delighted to hear then, if you haven't heard yet, that the old-fashioned concept of SEO is deader than last week's sandwich. Google pretty much pounded the crap out of keyword stuffing and other absurdities with the search algorithm changes it's made over the last couple of years. And then Google made search secure, which means you can't even see what keywords someone used to get to your site. It's about time, because all the minutiae blinded entrepreneurs to what is really important: making a connection with an audience. Really Know Your Audience One hour a day, read.

How many sites per pagerank toolbar value? Google Desktop Tools and Google Labs Projects forum at WebmasterWorld Side tracking from Brett's value of websites according to PR. [webmasterworld.com] How about guestimates on actual numbers of sites of which the highest ranking page has a PR of: 10 - Three 9 - About seventy (see this overview of PR9 & PR10 sites) [webmasterworld.com] 8 - about 4.200 7 - about 180.000 6 - about 850.000 5 - about 2.500.000 I am also interested in ways/methods of estimating these numbers - any ideas? The PR10 and PR 9 sites are easy. One way of estimating the total number for the lower PR5 to PR8 sites is checking the above mentioned company rankings [directory.google.com] and estimating how many fall into which pagerank value. DMOZ lists 383.000 categories so they claim. Guessing the number of PR5, 6 and 7 sites is much more difficult. Google claims to have indexed approx 2 billion webpages.

SEO Pricing: 600+ Agencies Share Costs of Services & Pricing Models Near the end of December 2011, we ran a survey on this blog asking consultants and agencies of all sizes and geographies to contribute their pricing models and cost structures. I'm pleased to share the results of that survey in the hopes that it will give everyone in the search industry a better idea of the range of fees and the services provided. Obviously, this data is imperfect - SEOmoz is not a professional data surveying firm and our only tool was a basic list of questions on SurveyMonkey. (via AYTM's infographic) Do note that while 600+ responses were received, we've elected to share data only from those regions with 10+ responses (490 total), which include: United States - 287 respondents United Kingdom - 76 respondents Canada - 34 respondents Australia/New Zealand - 28 respondents Germany/France/Italy/Netherlands - 34 respondents India - 31 respondents Top 9 Takeaways These are my personal takeaways from the data: Infographic from AYTM Data Dump Files

Miss Morrison How to Measure SEO Success Correctly measuring the success of an SEO campaign can vary greatly depending on the type of business you're in and your objectives. However, there are three key performance indicators (KPIs) that should always be considered when measuring an SEO campaign's effectiveness: Rankings TrafficConversions Not only can the information gathered from these three KPIs enable you to accurately measure your campaign's performance, they can also provide you with actionable data to improve your campaign over time. Rankings Keyword rankings are the most common and obvious KPI, especially when studies show that websites listed on the first page of Google receive up to 92 percent of traffic share. For example, let's say you're tracking 20 keywords, and all but five of these are on the first page of Google. On the other hand, you may discover that these keywords are simply too competitive, and based on your research, would not provide enough benefit to warrant the effort.

Canonicalization - Centre d'aide pour les webmasters This is probably more information about canonicalization than you need to know, so feel free to skip it. However, we'll provide it in case you like this sort of thing. When Googlebot indexes a site, it tries to determine the topics covered in each page. If Googlebot finds multiple pages on the same site that seem to be about the same thing, it chooses the page that it thinks is the most complete and useful, and marks it as canonical. The canonical page will be crawled most regularly; the duplicates are crawled less frequently in order to save crawling budget on your site. Google chooses the canonical page based on a number of factors (or signals), such as whether the page is served via http or https; the user's declared preferred domain; page quality; presence of the URL in a sitemap; and any "rel=canonical" labeling.

Use Open Graph to Get Video Thumbnails into Search Results Joel Harvey is, among other things, the Video Scientist at Conversion Sciences. Over the past four years, he has developed video strategies for a large number of online retailers. We’ve found that video is great for drawing and converting qualified search traffic, so I asked Joel to tell us his tricks for getting video ranked on Google. He doesn’t disappoint. Search marketers are always looking for strategies to give them an edge. The Opportunity According to Joel, one of the most mysterious and difficult universal channels has been video, particularly getting video thumbnail images associated with the search results that you rank for with your domain. Notice how video thumbnails make search entries stand out. It’s important because these thumbnails capture searcher’s attention and can “make a number three ranking perform like a number one ranking” in terms of click through rates and traffic. The Problem In the beginning of Universal Search, Joel used a process that was relatively easy: eBags
