Interesting website 1. feels to plain ( logo is name of website.. no images can capture the spirit of the website?) 2. Dating Ad (sidebar)- Change to a technology oriented ad 3. Tags: tag relevant words for the posts 4. On Post: Remove top ads - In place put picture of topic(seo it) - traffic additive The site overall tells me your are going to quit in a short amount of time because the attention to detail versus ad placements
Having dating site ads maybe isn't appropriate for your target audience! I'm not sure what the purpose of the site is, as in why I would want to download these presentation. If you explain it (briefly), in your header perhaps, it will confirm to the visitor if the site is what they are looking for or not, plus it may help your SEO as people may well use a search query related to it. I think the AdWords blocks o the presentation pages are too big - at this point, a visitor is trying to see if the presentation meets their need or not, but there may be only a few lines of the text visible "above the fold" because the ad block takes up so much of the page. Hope this helps.
