Reading this post you’ll find the positive and negative places to get links.
Let’s have the bad stuff taken care of first. Link brokerage is normally bad. There are numerous reasons. To start with Google can readily detect those back links using reverse engineering and penalize your rankings. Second of, they often link in the market to spammers and you should not produce good results regarding rankings.
1) Paid directories: Spammers prefer quantity over quality. Payment often serves as a good barrier to entry. This means that a spammer will endeavour to place links on 1000 ineffective directories and avoid investing in our prime-quality directories. Virtually all paid directories have staff that reviews submissions. Search engines like sites reviewed by humans and provide them more trust. Priciest directories are dir.Yahoo.com and business.com.
You should review them manually, because unfortunately many of them change for that worst. In the course of this writing they may be still good. Also Check your local directories (especially effective for local brick-and-mortar businesses)
This is exactly what you can even examine: Do they really accept all listings automatically after you pay them? In that case it’s not really a good sign because spammers may buy links also. How creating backlinks does the directory have? The frequency of which can it get crawled by Google (check info.directorydomain.com to discover last cached date)? Exactly what is their Alexa rankings (how much traffic can they get)?
You may exchange links with directories, only if they’re vertical directories highly relevant to your industry. An effective approach is to make a directory yourself and populate it with listings. Use it to prrlinks to directories which require a link back in exchange for a free of charge listing. Never link returning to poor quality directories.
Carefully examine the “directory submission services”, often times they own all the directories that they’re submitting. This will likely create inferior backlinks for often astronomical prices.
2) Donations: Many non-profit organizations have a listing of people who crafted a donation. It is possible to come up with a small donation and obtain a web link returning to your blog. A number of these places have common keywords on-site for example “nfp”, “npo” etc. Try searching for these keywords to find these organizations.
