There are many ways to do 301 redirects, but the most common method is to edit your site’s .htaccess file.
You’ll find this in your site’s root folder:
Don’t see the file? That means one of two things:
Here are some snippets of code for adding common types of 301 redirect via .htaccess:
IMPORTANT. These instructions are for Apache web servers only. Read this if your site runs on Nginx, or this if your site runs on Windows/IIS.
Using WordPress? Remove the need to edit the .htaccess file with the free Redirection plugin.
It makes adding 301 redirects as simple as this:
IMPORTANT! If RewriteEngine on is already in your .htaccess file, do not repeat it. Just copy the rest of the code. It’s also possible to do this in Cpanel, which may be preferable.
Here’s the non-www to www version:
Here’s the www to non-www version:
IMPORTANT! The placement and order of code in your htaccess file matters too. You may experience unwanted effects if multiple instructions are placed in the “wrong” order (., redirect chains, etc.). If you’re planning to implement a lot of 301 redirects in your htaccess file, this is something worth looking into.
IMPORTANT! You must have an SSL certificate installed on your website for this to work. Otherwise, you’ll get the cautionary “Not secure” message.

By this stage, your website should be free of any SEO-hindering issues related to 301 redirects.
Now it’s time to get serious and talk about how we can use the power of redirects to massively boost organic traffic.
Here are two methods for doing that.
You have a glass of Coke. Mmm. You have a glass of rum. Tasty!
Both of those are great drinks in their own right. Combine them, however, and you take things to another level.
So how does this relate to 301 redirects?
Think of both these drinks as topically-related pages on your website. They’re each performing okay. They have a few decent backlinks. They get some organic traffic. Not too bad at all. But why not merge and consolidate those two pages into one to make something even better?
In doing so, chances are that we could transform two average-performing pages into one delicious cocktail of a page that performs way better!
We recently did this with two of our posts on the Ahrefs blog:
Both these articles were getting old, so we decided to merge them into one new guide.
We then republished at and redirected the other article to that.
The results speak for themselves:
So why does this work?
Two reasons:
Now, the only question that remains is how to replicate this strategy, right?
Here’s the process.
Keyword cannibalization is when two or more pages target and rank for the same keyword(s). Finding such issues is a good way to identify opportunities.
So, first things first, make a copy of this Google Sheet.
Next, paste your site into Ahrefs’ Site Explorer, head to the Top Pages report, and export it to CSV.
Import the CSV into the first tab of the Google Sheet.
To do that, Go to File > Import… > Upload > Select the CSV > Choose “Append to current sheet” when asked
That’s it. Go to the “Results” tab and you should have some refined results.
Next up, you need to eyeball the results sheet for potential redirection opportunities.
Here’s a good example from the Hubspot blog:
These two pages rank in positions #5 and #6 respectively for “user generated content.”
Both of them:
So let’s take a look at top-ranking pages for “user generated content” in Ahrefs’ Keywords Explorer:
Two things stand out about the current top-ranking page:
So if Hubspot were to merge these two posts into one, and consolidate all that delicious “link juice,” then I’d say they’d have a good chance at claiming the number one spot. This could potentially 2x their traffic!
Now it’s time to take the best things about each page and combine them into one.
For example, if we were doing this for the aforementioned Hubspot articles, we’d probably keep the section about “How to Run Your Own User Generated Content Campaign” from one post:
… and keep the part explaining “Why User-Generated Content?” from the other:
To keep the relevance of the new page as high as possible, and mitigate the risk that Google will treat our 301 as a soft 404, we could also check the Anchors report in Site Explorer for each page:
This gives some insight into why people linked to the pages in the first place.
For example, I can see that a fair few people are quoting statistics when linking to this page, so it may be worth keeping those stats in our revamped post.
You should also take the rewriting/merging of two pages as an opportunity to better serve search intent and give searchers what they’re looking for. If there are a lot of top 10 lists ranking for the target keyword, make your new revamped post a top 10 list. If there are a lot of how-to guides, well… you get the idea!
NOTE. That has nothing to do with 301 redirects, but it’s worth doing if you want to maximize the ROI of your efforts.
Now it’s finally time to publish your revamped post/page.
If either of the old URLs is a good match for your new post, then feel free to republish at the same URL. You can then delete the other post/page and add a 301 redirect to the new post.
You may recall that’s what we did with our skyscraper technique post. We reused the /skyscraper-technique/ URL.
If neither of the old URLs is a good match for your new post/page, then it’s also perfectly fine to 301 redirect both pages to a totally new URL.
For example, if we were to merge those two Hubspot posts into this guide:
… then neither of the two old URLs would really fit the bill.
It would be better to publish at something like
So, we could do that, then 301 redirect the other two pages to that URL. Simple.
Looking to take this idea even further? Do a content audit to find pages with no organic traffic or rankings that still have backlinks.
If these pages aren’t important to your business, delete and redirect them to a relevant page that does matter.
Here’s what happened to one site’s organic traffic after using the merger method:
That’s a ~116% traffic increase in 12 months!
Here’s the process in a nutshell:
Backlinko’s Brian Dean did this last year. He bought another SEO blog—Point Blank SEO—and redirected it to Backlinko. In fact, it was he who used this method to achieve the results you see in the screenshot above.
But before you start buying every website you can get your hands on, understand this:
Having success with this method isn’t as simple as just buying any old website and using 301s to redirect all pages to your homepage. That’s the lazy approach, and in 2019, it’s not a good idea. You also need to implement 301 redirects on a page-by-page basis.
Here’s how to do it, step-by-step:
The biggest traffic gains are likely to come from re-homing and redirecting content.
Brian Dean did this with some of the posts on , including Jon’s infamous list of link building strategies.
You know, the one with this backlink profile:
This original URL was:
The new (redirected) URL is:
Because Brian moved the post from the old domain to the new with a 301 redirect, all of those links now effectively point to that same page on instead. The page has effectively just moved to a new home.
The re-homing and redirecting of content is the best option when all of these apply:
Note that you can combat that final point but updating or rewriting the content after moving and redirecting it. Brian did this with that list of link building strategies, which hadn’t been updated since around 2012.
There’s no point keeping or re-homing pages that:
For example, there’s no point keeping the about us page from the website you’re merging because then you’ll have two about us pages… which makes no sense. This is also true of other pages which target the same keywords as existing pages on your website.
Re-homing these will just lead to keyword cannibalization issues.
Similarly, if pages have little or no traffic potential, then you may as well get rid of them and redirect elsewhere. This is what Brian did with quite a few posts on , such as this post about outreach platforms:
That post no longer exists. Brian redirected it to his blog post about link building tools.
This original URL was:
The new (redirected) URL is:
He did this because the keyword “outreach platforms” has no search volume and no traffic potential. It’s not a topic worth targeting.
So it made more sense to redirect this post to another relevant post with traffic potential.
If there’s nowhere relevant to redirect pages, and it doesn’t make sense to move and re-home them, then the last resort is to redirect them to your homepage.
Brian did this with most of the pages on , such as this ego-bait guide:
This original URL was:
The new (redirected) URL is:
Why is this a last resort? Well, remember what we covered earlier about Google treating irrelevant 301 redirects as soft 404’s. This may happen when redirecting posts and pages to your homepage.
But here’s the thing: if you don’t redirect these pages, then there’s a 100% chance of Google treating them as soft 404’s. Conclusion: you may as well redirect them.
There’s one caveat to this, however, which is that you shouldn’t redirect pages with low-quality backlinks. Doing this is likely to cause more harm than good, so make sure to check the Backlinks report in Site Explorer for each page before redirecting.
If the backlink profile looks like this…
… then it’s probably best to just delete that page and leave it as a 404.
Or, if you really feel the need to redirect the page, then you could disavow the bad links before doing so. However, this is likely more effort than it’s worth.
301 redirects have a lot of uses when it comes to SEO.
Use them strategically and you could see huge gains in organic traffic. However, it pays to make sure there are no existing problems with 301 redirects on your website first, as these could be hindering your current and future SEO efforts.

A 301 redirect indicates the permanent moving of a web page from one location to another.
The 301 part refers to the HTTP status code of the redirected page.
Example: redirects to
In simple terms, a 301 redirect tells the browser: “This page has moved permanently. This is the new location and we don’t intend on moving it back.” To which the browser responds: “Sure thing! I’ll send the user there right now!”
That’s why if you try to visit , it won’t happen.
You’ll end up at instead.
