I have read almost everywhere that dropping links of your website in your forum signature is helpful to get backlinks. I think it is a time-consuming task because most of the forum allows adding a signature after specific post. For e.g., XYZ forum allows to add a signature when you have 500+ post, so it required huge time and patience too. Do you really think those signature backlinks are worth?
If you are looking for the good amount of link juice then it is good.
Forum participation is a very old method and worthy too!! But it is not alone enough to get your website on the top. SEO is getting competitive and you need to explore your link building strategies. Get backlinks from your niche related websites and diversify keyword in the anchor text.
I would like to highlight Google policies for Forum Profile Backlinks:
1) Profile link should not be optimized with the keywords
2) If links were not placed editorially then it is considered as unnatural links or violation of guidelines.
3) If links are generated automatically, it affects the website ranking.
After submitting signature on the forum I will recommend using tag manager. It will help you to follow the source links that you are getting from the forum.
It is beneficial no doubt, but it should be used in a specified way on the forums. More usage leads to bad results for the website and it does not give more value to the post and quality links.
Yes, they are worth enough and orthodox way of link building. It needs lots of patience for the same, but surely you get a good amount of link juice and improves SEO ranking.
Forum signature are important. You can add company offerings at signature site. Also, forum users can check for users services/products.
A relevant forum consisting your targeted areas and business can help you in increasing traffic and backlinks and add value to your domain.
Along with the forum signature backlinks, you need to explore other sources as well, for your backlinks.
