For example I want to use these two phrases: product rating and rating product Does it make sense to use both in my meta keywords? Are these different keyword phrases, or google finds them identical? The thing that made me think about, is that both phrases have the same results for competition and searches. I dont believe its coincidence. I liked, four more phrases that have the same results among themselves. To understand me, here's an example of the above: rating about product rating on product ...and so on (the only difference is the word that connects them, like "on" and "about") So I must use them all in my meta keywords, or pick one and use it only? Thank you in advance, and I apologize if there is a similar topic.
Well, "product rating" is something else in terms of keywords like "rating product". If you use Google keyword tool and search broad, there will be the same number of monthly searchers. Why? Because broad means: including these two words in whatever order. If you try "Exact" match you should get a different result. If not, it must be a coincidence. And you should target those two keywords if you've decided that these ones are the ones. If these are the main ones than include them in meta tags of your webpage. The next step I'd do is to make a post targeting just one of them and second post targeting the other one. Hope it helps..
I always use the one that has, in exact search, the best competition / searches ratio and add the other variations naturally to the body text.
Stick to the one that has a higher number of searches when you do an exact search. The other ones are just variations of the original.
