It seems there is never a consensus on what perfect on-page SEO really is. Partly because it's always changing and partly because there is a lot of misinformation floating around on the web. So I propose share our experiences on what works right now in this thread. From my experience in ranking sites over the last year, this is what I think is good for on-page SEO right now: 1. Proper Titles and Meta Tags - standard notions about titles and meta tags still work good on google. 2. Good Site Structure - no broken links, urls that make sense to search engines, no tag/category spam, etc. 3. H1/H2 tags with partials or LSI's instead of exact match keywords 4. Unique Content, the more unique text, images and videos the better 5. Easily readable text. Not 100% sure about it but it seems like sites with better readability score tend to get higher initial SERPs for me. 6. 1% KW density. We want to inform Google what the page is about not keyword-stuff. Higher densities get me good results on Bing, but not so much on Google. These are just a few things that work for me, I may share more later. Please add anything you find works well in practice so we can make this a great thread about On-Page optimization!
