Q. What is a seedlist and how does it work?
A. A seedlist is a list of websites that our crawler will run through as it looks for expired domains.
The crawler will move through the pages of these websites searching for outbound links.
Sometimes these outbound links will point to a broken page, and our software checks to see if these broken
links point at an expired domain. If the domain is expired, we then run it through our quality checks and if it’s an
authority domain useful for SEO, we present the data in “My Crawls”.
Q. What are manual seedlists and when should I use them?
A. We give you the option to upload your own seedlist, rather than using our automated option.
Our automated seeds are great for getting a supply of general domains across lots of niches but the manual
seedlists when used correctly will help you find more specific niche relevant domains or target regional ltds.
Your seeds should therefore include the the kinds of sites most likely to link to the domains you want to purchase.
We require a minimum of 2k seeds, the optimum number is 3k.
Q. What does the “Crawl Backlinks” option mean?
A. If you have less than 2k seeds for your manual seedlist, you can select the “Backlinks Crawl” option,
which will mean we crawl the backlinks of your seeds rather than the seeds themselves.
This will generate enough seeds for a full crawl to run.
Q. Do I need to run crawl results through the “Spam Check” filtering option?
A. No you don’t. All of the crawl results with SERPDrive automatically include spam checked domains as standard.
You only need to use the “Spam Check” feature if you are importing a list of domains from elsewhere
(eg. expireddomains.net / scrapebox etc) and need to filter them.
Q. How deep in a seedlist does the crawler run?
A. Each $12 crawl will go 7200 pages deep within a website or less if the website is smaller than 7200 pages.
Once our crawler has run through the pages of a seed, it then moves on to the next seed.
Q. How many seeds will be crawled with $12 credit?
A. An average crawl will run through 3k seeds.
Q. How large is our database of automatic seeds?
A. We have a full database of 100 million seeds. We spent 12 months generating and testing this list
and categorized the seeds based on their specific topics.
If two users run the same Topics with automatic seedlists they will not necessarily crawl
the same seeds as our database is so big.
Q. How often are our automatic seedlists updated?
A. Our seeds are updated weekly.
Spam / Quality Filtering
Q. How does the spam filtering work?
A. We check the history of a domain at archive.org and analyse it’s content.
If there is evidence of Chinese/Japanese language or too many instances of spammy keywords
(eg. porn, loans, forex) then we will mark the domain as a previous PBN and therefore filter it out of the results.
If it passes the domain then goes through a 2nd round of spam filtering, where we check the backlinks,
url and anchor keywords, for any further evidence of spamming.
Q. Should I manually check my domains for spam?
A. Our spam filters are extremely accurate and we cut out about 95% of the spam sites in first round filtering,
saving you hours of time going through the archives & backlink history.
We do recommend running your own quick manual checks over the domains you wish to purchase from the filtered
results - just to make sure the domain did not sneak through the strict automatic spam checks.
Q. What metrics are included in the results?
A. We use the the Majestic API to bring back information on Trust Flow, Citation Flow, Topical Trust Flow,
Total Referring Domains, Backlinks, Anchors and the top ten referring domains linking.
Q. How do we determine whether a domain passes the SERPDrive authority test?
A. Domains must have passed through our spam filters and have at least a decent TF score or a solid number of referring domains.
We will sometimes pass domains through the filtering if they have a lower TF score but have a high topical relevance.
We also allow domains to pass if they few referring domains but a very high TF score. If the TF/CF ratio is too high -
we also fail a domain for spam.
Q. Can I get local national TLDs?
A. Yes SERPDrive brings back data on over 60 TLD regions.
Most of the results from our automated seeds will deliver international results not national,
but if we find any based on your TLD criteria we will include them in the results.
If you are only interested in TLDs from a specific region we recommend using the manual seed option -
your seeds should only include websites with the TLDs you want results for.
Q. Which TLDs do you support?
A. com, net, org, info, biz, mobi, io, co.uk, uk, ca, de, fr, us, ch, it, nl, se, be, dk, pl, in,
eu, co, com.au, net.au, org.au, net.nz, co.nz, tv, cc, co.il, org.il, xxx
Q. Why are some of the domains in the results not indexed?
A. It’s quite common for expired domains to temporarily drop out of the index once they expire -
this does not mean they have been targeted and actively de-indexed by Google. 97% of expired domains
that drop out of the index will then re-enter the index within 10 days of having content uploaded to them.
Q. Why do my results include domains with different niches?
A. All our seeds are selected and categorized based on their topical TF in Majestic.
This doesn’t necessarily mean they only link out to domains with the exact same topics but they are more
likely to link to similar sites. In My Crawls results we show all the domains no matter what their topic;
many will be the same topic as the seeds, many will be a different topic.
Q. Will other users see the same domains that are in my crawl?
A. It will be rare but there may be some domains that cross over. This may happen if crawls are run at a
similar time period and the crawls both discover the same domain. This can happen if two different seeds
link to the same expired domain or the same seed is crawled during 2 different crawls.
Q. Why did my crawl last shorted than 2 hours?
A. The crawl will finish once we have checked 6000 expired domains.
These 6000 will be filtered and the best domains selected in My Crawls information.
These 6000 domains may take up to 2 hours to review, but often shorter.
Q. Why is my crawl queued?
A. If there are too many users crawling at the same time, some crawls will be queued
so that we can run everything through our spam-checking filters.
