How to Use These Tools Together in Your Off-Page Workflow
These tools are powerful in their own right, but when combined they create a powerful team. The following is an example is among the best Chrome extensions for Off-page SEO & link building;
Step 1: Finding Prospects
Start with a Google search on such terms as best gardening blogs or gardening resources. The Domain Authority (DA) or Domain Rating (DR) of every site will be immediately displayed in the MozBar or Ahrefs SEO Toolbar. This also allows you to easily concentrate on powerful and authoritative websites and disregard the weaker ones.
Step 2: Qualifying Your Prospects
Click a promising site. First, check its traffic at Similarweb. When it receives numerous visitors monthly, then it is good. The second step is to use the Nofollow extension to see some of their posts. Are the following links provided to other sites or are all links no-followed? They are a fine prospect in case they give the following links.
Step 3: Finding an Opportunity
You need a reason to reach out. Visit their resource page and search broken links with the help of a tool named LinkMiner. When you come across one, then you have a good chance. Or, make a list of other sites you may want to contact with a tool such as Scraper on their resource list.
Step 4: Finding the Right Person.
Once you have an appropriate place and a reason to get in touch with them, you require an email address. Click the Hunter extension. It must give the name and email of the blog editor or content manager in a couple of seconds.
Step 5: Sending Your Pitch
You now possess all the elements, a qualified site, a good reason to e-mail (e.g., a broken link), and the email address of the right person. Send a friendly, accommodating email, and attempt to receive that link.
Limitations & Caution Points
They are terrific tools, however:
- Data is an Estimate: The numbers on such metrics as Domain Authority and traffic are good guesses, but not 100 per cent accurate. Take them as a guide and not the last word.
- Stop Installing Extensions: Every extension consumes memory in your computer. Putting a lot of them simultaneously and leaving them all running can reduce the speed of your browser. Install only when you require it and enable it only when you are working on SEO.
- Free plans are not unlimited: tools such as Hunter have a limit to the amount of searches per month. Use them wisely. Free searches should not be wasted on sites that do not suit.
- Tools Do Not Substitute a Brain: The extensions will provide you with data; it is up to you to act on that data making wise decisions. Connection with a less-authoritative but highly relevant blog may be more precious than one with a generic high-authority site. Consider first relevance and quality.
