if i want for may website to appear on first page for the keyword "Apple" would the use of 2 keyword combinations likes "Apple Cider", "Apple Vinegar", "Apple Juice" be enough? some SEO expert says that if i want to SEO for single keyword like "Apple" then my anchor text should also be a single keyword and it should only be "Apple" and i should avoid using 2 word combinations for my anchor text like Apple Cider. Apple Vinegar etc. because i would only be optimizing my website for Apple Cider or Apple Vinegar.
Why use a single word? It doesn't describe what your site is all about. If its about apple juice, use that phrase. I would use a bit longer if it applies, unsweetened apple juice maybe? How many people would search on just apple? Even if you could get top spot anytime people use apple in their search term, it would not be targeted to what they were really searching for. You would not get many click throughs and those who did click would not be of great quality. Take me for example, an Adwords account manager. Optimizing on just Adwords is a waste because I wouldn't get anywhere near the top and doesn't describe my service. Adwords management is better but still would not get top spots. That's why I optimize on Google Adwords management and even better, Google Adwords management services. It describes what I do, there's a fair amount of people searching that term and get fairly good ranking. My listing should get people to click on it and my page, hopefully, should get me some clients because that's what they were searching for and that's exactly what I offer. My offer is not Adwords, or apple in your case.
