I just want to know from link building merits, is it a good practice to receive Site wide Links ? If so, kindly let me know it merits and demerits ?
Sitewide backlinks from high quality sites / blogs will easily increase your PR and will certainly help you in SERP. Just be careful when you have to build backlinks for a brand new domain. Sitewide backlinks might send it in Google sandbox. In all other occasions you will be doing fine with sitewide backlinks. Even better if they're somehow related to your niche.
The more the better This is true of sitewide links as well. Like zexy said though, if it's a new site you might experience a temporary sandboxing, but keep pushing through and getting more sitewide links - they are great!
A sitewide link on a trusted and relevant authority site is valuable, but it counts as a single link, in spite of the fact that it appears on multiple pages. Some SEOs speculate that Goog regards sitewide links as spammy, but I don't believe this is a concern if such a link appears on a trusted and relevant authority site.
Sitewide links are really good for the site. Now say, I own a video portal. When I have links building up for one of my inner pages,say, a video page, the popularity is shared for the domain as a whole. Moreover, for other textual content oriented sites, you tend to get ranking for contextually relevant queries. So sitewide links are good for multiple reasons. Hope this information helps
Very good discussion here! I also need help to get more back links for my website that is related to repair materials or products. Please suggest me, how can i do?
I think its more complex than this, I would prefer for Google to index the homepage link from a relevant high PR site than the entire site, if the content on these pages isnt as relevant as the main page linking to my site.
Yea... Good luck with that approach. Good luck getting that home page link from a relevant high PR site. If you can get a home page link from a relevant high PR site, you can probably get a site-wide link from them as well, so go for it all. There is no such thing as a "bad" inbound link UNLESS you bought it and Google KNOWS you bought it. Site-wide links from Site A with link text "my keyword phrase" will always help my URL rank for the search phrase "my keyword phrase" more than a single contextual link from one relevant page on that same site with the link text of "my keyword phrase". With the site-wide link you'll get credit for a link from that "relevant" home page you're so worried about as well as other relevant and possibly irrelevant pages on the site. But even the links from irrelevant pages will help. One might also argue that if the home page is about some relevant niche or topic, typically most if not all of the pages on the site are also about that same niche/topic, just different areas within that niche and likely more specific sub-topics within that niche. So every page on a site would typically be relevant, just to varying degrees, if the home page is relevant.
