I have a little misunderstanding regarding keywords. Let's say I have a website about chickens and I want to rank good for the 2 keywords: 1 - "buy chickens" 2 - "buy chicken eggs" How should I make the keywords?Something like "buy chickens, buy chicken eggs" OR "buy chicken eggs, chickens" OR "buy chicken chickens eggs" ? Please, I am waiting for some really relevant answers since I have tried to find the truth for quite some time now.
You can just build links surrounding both keywords because if you're able to accomplish the keyword "buy chickens" you shouldn't have a hard time getting the keyword "buy chicken eggs". If you want to get both keywords just edit your homepage to have some type of content that relates in some shape of form to that keyword.
Use keyword suggestion tool and target a keyword which is semi-competitive. If you already decide on what keywords to target create your content using that targeted keywords.
Both phrases are different. To rank high in SE, you have to get anchors for particular phrases separately.
isn't "buy chickens, eggs" better? i heard that you might need to combine the words dont repeat it too often.
it is not repeated there too often! just 2 times your keywords (buy chickens, eggs) is suitable if your goal is : "buy chickens" OR "eggs"
the keywords for search robots are only logic unit. if you want good ranking for both of them, the better way is to use them separately and clear ("chicken eggs" and "buy chicken eggs" for separate links). if you will try to search google for any keyword, you will see that first results almost always for exact string and after that all combinations.
