i have a blog on which i want to categorize diiferent recipes under one heading.I will give a separate link to each post for that.So i will be removing my archives section from my blog.Will his affect my present search engine rankings?
SE will need some time to crawl your site and take into account your new architecture and internal linking structure. That may affect your site for a week or 2 and then if your internal linking is clever you'll be back to normal or better. Don't do that too often though, SE like stability for this kind of thing usually. HTH G.
