Hey everyone, if there is enough interest in this I will post my entire case study. But to start, let me overview what I did and the kind of results I found. What I did: I Registered 30 websites. (10 websites in each of 3 different niches) I Wrote 15 pages of content for EVERY site. Every article was unique. HOWEVER, I changed keyword density, title tags and word placement. Without adding any links, I recorded the positions and ranking changes of each site over time Notes: The goal of the study was to test the effect of content on rankings and determine the best way to write content. The keyword's I aimed to rank for WERE not in the domain (I tried to eliminate any extra variables) All domains were on separate C blocks, and each was newly registered. Variables Tested: The articles varied slightly in keyword density. (.5% all the way up to 5%) I changed title tags, and my usage of h2 tags I changed word positioning and studied the patents on LSI indexing. Word count varied. Some sites focused on 200 word articles, while others averaged 1000 words. Simple sentence vs Complex Sentence usage Image usage vs Non Image Usage The best way to break up content THE RESULTS: After adding 2 articles per week, for a total of 6 weeks, I have recorded quite a bit of data. It seems that the most important factor in Googles algorithm is the 6th to 9th word in each article. Look at any natural page of content, you will notice that the 6th to 9th word in each paragraph usually is the focused content of the article. Another observation was the fact that keyword density only plays a negative factor in large articles. In articles with less than 200 words, a keyword density of 5-10% DID NOT hurt the rankings. On the other hand, articles of 1000 words could only get away with a 2.5% keyword density. (Anything more than that hurt the results). It is better to make the H2 tags SYNONYMS of the H1 tag, as opposed to secondary keywords you want to rank for. Content and On-Site factors compose roughly 60% of Google's algorithm. Half the sites had images, the other half did not. The sites that had images FAR OUTRANKED the sites that did not. Top 5 Content Writing Tips: The more H2 tags the better. 150 words per H2 tag is the ideal range to achieve best rankings. Make the 6th to 9th word in each paragraph the keyword you want to rank for Bulleted points are amazing for rankings. Google gives extra value to keywords after bullets One image per 200 words is the PERFECT ratio. USE IMAGE More words = lower keyword density. Less words = higher keyword density Wordpress Tips: Use POSTS not Pages. Tags tags tags, the more tags the better. Categorize and interlink your articles. An HTML sitemap is key. Yoast is the best on-site plugin, in my opinion. There you have it. A 2 minute overview of my case study. For those of you that like stat, I have correlating spearman data for 45 different factors. Each of the 30 sites have ranking tracking over the 8 week case study. I noted EVERYTHING. If there is enough interest for a complete data analysis, I could do that.
Yes, anyone can get a top ranking at Google without backlinks. Make sure to choose keywords which have low competition at Google and provide good quality contents for targeted keywords.
Thank you very much for your post from which i learn a lot. Yes, a sitemap is extremely important for site indexing. Can anyone tell me which kind of sitemap generator is better?
On page optimization is the most important thing I found after penguin update. If you write a great article then it will be on SERP within your chosen long tail keyword.
Yes, On-page optimization is very important part of SEO if we do proper and search engine friendly on-page optimization then we can get better result for our website.
Thanks a lot for sharing all of this data. Your observation about the 6-9th word is very precise. It is something I have not tried. What you said about the keyword density for short content makes sense and it shows that having a set percentage regardless of the length of the content may not be the post natural thing to do.
Thank you for this great study. It's almost a complete guide for on-page SEO. The images info is new for me. I will definitely try it out. And what about title, meta description, and keywords? Did you tried to variate them also?
