Top Link building mistakes:
1- Link to sites with bad reputation:
Never ever link to a site that had a bad reputation i.e., spam site, duplicate content site (auto-blogging, illegal sites, porn sites)
2- Buying/Selling Links:
Don’t try to buy links from other sites for getting backlinks. Sometimes, you may get banned from Search Engines for doing so. SEs only love natural links. Specially, Google made it very clear that selling and buying links are considered spam and should be avoided.
3- Getting No follow Links:
Top Link building mistakes Nofollow links are in no way useful for your website to rank in search engines like Google. However, if you want to rank top in Bing, then you can continue to build no-follow links. Else if you are targeting only for Google, it’s merely a waste of time.
Despite, spend a little more time getting at least few dofollow (quality) incoming links. Though, Google made it clear that they ignore the nofollow tag most of the time but again if you are working on building links, work on getting dofollow links. There are dofollow forums that you can easily target.
4- Backlink from only high PR domains (Low PR):
Yes, it’s a good idea to get backlinks from high PR sites, but keeping a mix of high PR and low PR yields a better results. If you build up too many high PR links and no PR links, it might not look authentic.
Though there is no straight away mention from Google about this and it can be considered as an SEO myth, though it’s a good idea to go for both, High PR and low PR.
5- Getting Backlinks from Irrelevant Niche sites:
An example of a quality backlink is a dofollow link from a high PR site within your niche (same topic). So try to get incoming links from same niche instead of irrelevant sites which adds very less weightage to your PR.
6- Links without your Targeted keywords in Anchor text:
The anchor text plays a major role. If your targeted keyword was used as anchor text instead of your name or your site name, then it will help you rank well for that keyword.
Note: Don’t use words such as “click here,” “check this” etc…
7- Tons of link building in short span:
Don’t try to build a lot of links at a time as your site may seem like a link farm in the eyes of the Search Engines. This may even make the SEs remove your site from indexing I .e.., Ban your website from being indexed. So never try to do link building in a hurry. Remember “Rome was not built in a day”. Slow and steady wins the race.
