hello, i had an old blog with some blog posts about a subject. i want to transfer these posts to a new domain that is related to this subject to have some seo advantage. i plan to 301 redirect these posts to the new domain. will this help me in ranking better than before ?? and if it will help i want to ask about the new domain. lets suppose that the main keywords "cars repair" which of the following domains is better for seo(notice that it is a very common subject and most of the domains already taken so the folllowing domains only are available) reviewscarsrepair.com (looks bad but cars repair reviews has good search volum but it is taken so i changed the order) a1carsrepair.com (or any similar) carsrepair-reviews.com
carsrepair-reviews.com is not very goos, but better than the other one . And 301 redirect I dont think i a good choice, better install wordpress on the new domain and import the old posts.
ok i will setup another another word-press on the other domain and i will import the articles but the old pages has pr 3 or 4 i don't want to loose it so i will make 301 redirect. or i am wrong??
