Which meta tags are you talking about? The meta description will cause your search listings to be out of context, ie: not snippets but whatever boring text you can come up with. I think you should FIRST, look at creating unique, interesting content that is presented with decent spelling and grammar. Even simple things there can make a big different like correct spacing after a . or , and no space before them. Not thinking like you are in twitter trying to skimp on your words, ie: dont say: "present unique metas on every pages", use more correct English such as "use unique meta tags on every page". But even that is not clear as there are many meta tags. "When using meta tags for keywords and/or descriptions make sure they are unique to the page, ie: don't duplicate a site description across all the pages." It just takes a little attention to detail to present your message with better clarity. Lacking clarity will result in a lack of success. |
