Hello everyone! I am making 10 web 2.0 with 1 articles each (buffer sites). My question is that: 1. Can I use those 10 articles for same targeted keyword? My niche is so narrow, were only 1 keyword of it got only 9k plus search a month according to google keyword planner.. The other got very very low searches. 2. I am planning to buy some high PR manual blog commenting service. I found 3 in the marketplace with good reviews. I want to use it in my 10 articles. 4 links(articles) for 1 seller while the other 2 sellers will have 3 links(articles), 3 same keywords for the 3 sellers.Is it ok? if not any advice? 3. Lastly, can I put an anchor link in the semi title of the article? i.e How do get a free microsoft points(this one) 2014? Not the title I mean, the start of the article like some introduction title before a paragraph where I mark it as (H2 Heading 2). and also 1 other keyword for diversity and 1 words like click here to visit the website. Is it ok? Thanks in advance!
