Now that we have looked at some of the best link-building agencies to consider, here are some of the key parameters you should keep in mind while selecting the right one for your business.
The first step to choosing the best backlink service for your company is getting a better understanding of your marketing goals and objectives. When you have a clearer picture of your marketing needs, you can communicate them effectively to the agency you hire to help with your link-building strategy. After all, learning about your marketing needs in detail will only help you tailor the perfect link-building strategy to target your goals.
Before choosing the right link-building agency for your marketing needs, you must evaluate their expertise and experience. You must ensure that they are capable of providing the best backlink-building service required to expand and strengthen your backlink profile.
Start by analyzing all the existing content and SEO-related projects that the link-building agency has carried out for its clients. You can ask for their samples and check out case studies to gauge their link-building expertise. Even if you find a highly reputed SEO agency offering all the essential SEO and manual link-building services, evaluate their link-building expertise specifically to determine whether it is the right fit for you.
There are several ways to approach link building as a process, and many companies and agencies resort to black hat techniques to generate faster results. These techniques, however, fall flat in the bigger picture and even lead to penalties for your website.
To avoid these challenges, ensure that the chosen link-building agency offers periodic reports and updates on your link-building campaign. Most agencies will even provide a dashboard or spreadsheet listing all the domains and content pieces through which your links were built. Avoid associating with agencies that don’t have a proper reporting system in place.
The link-building agency you choose should also include key metrics that demonstrate the success of their link-building efforts. Additionally, they should also evaluate your backlink profile and the impact of the backlinks on your overall website performance. The agency must include these findings in a comprehensive performance report that helps you measure the ongoing impact of their monthly link-building service over time.
Lastly, you must rely on the feedback and testimonials of the existing and past clients of the agency before you decide to partner up with them. Go through the case studies on their websites and ask for more related to your niche, if necessary. You should also check out the reviews and feedback the agency has received from clients on third-party websites and directories.
Link building is often considered a small part of a much bigger SEO strategy, which is not incorrect. However, even seasoned SEO professionals may lack the expertise required for building links and strengthening your backlink profile. You will find that expertise in any of the aforementioned agencies, but be sure to use the parameters mentioned above to evaluate whether a link-building agency is right for you.
