For example: I have two keywords: keyword x and keyword y. X is the mainkeyword that I want to target. How do I have to write the content on the home page if I want to target x? And do I have to make a new page for keyword y or do I have to put that keyword also on the home page and link that to an other page?
It's not a way to rank better.you need to work on quality of article.if your article is high quality then you will rank both KW.no need to make separate post for "Y" KW.
You can do this one or two ways. I generally try to use 2 keywords per each page/post. You can do this or you can make individual posts/content for each keyword. what cms are you using?
It depends how synonimous your keywords are. If they are pretty synonimous, go with one article by all means. Then use one keyword in title and the other in desription. Google doesn't like keyword optimized meta now so synonims will allow you to fly well below the radar and give you better Seo score.
You dont need to make separate post if the keywords are closely related. just make sure they appear on on the title and description. Dont over optimize your page too much by stuffing your content and tags with your keywords. The Big G (Google) doesn't like that. You'll end up crashing and burning if you do so.
What is important to keep in mind is this: headlines, context, content. When you are building the content think that a 50 word phrase can make people to buy. If you are not specialized in creating website content you need to hire a professional copywriter, able to sent the searchers straight to the CTA (Call-to-Action) form.
Try to incorporate 1 or 2 keywords per paragraph. That should boost ranking while avoid being seen as keyword stuffing.
SEO content writing is th Yes this is a good way to target Keyword X and keyword Y that use one keyword in title and the other in description.
The following points may help you: 1. Add main keyword in heading. 2. Use only 2-3 times main keyword if content is more than 500 words. 3. You can use secondary keyword at home page but create a separate page for it. 4. Link to secondary keyword placed on home page with separate page for it would be good idea.
