Hello friends, Can I use the same description tag for some of my other similar sites. If no please let me know the reason? Please give your valuable suggestion's... Thanks
Yes you can do it but I recommend not to do that. Search Engine will find that duplicate, quite possible the you website will be penalized.
These paragraphs are your opportunity to advertise content to searchers and let them know what the page has that they are looking for. A good description will get you more click-through visits to your site. Take the time to prepare each description carefully for best results.
