Different MLSimport tools keep your site accurate by blocking bad data early or cleaning it on a schedule. Some systems just show whatever each MLS sends, which can create duplicates and leave withdrawn homes hidden in the backend instead of removed. MLSimport avoids most of that mess by using focused RESO feeds, local WordPress posts, and frequent sync rules that remove inactive listings. Those same syncs keep status changes close to the source MLS(Multiple Listing Service) so buyers see the real state.
How do MLS import tools prevent or create duplicate property listings?
Most IDX plugins don’t automatically remove duplicate listings when you connect overlapping MLS feeds.
Many tools just load every record from each MLS you connect, so the same home can appear twice when it lives in two boards. MLSimport usually connects one RESO Web API feed per site or per import profile, which keeps each property tied to a single source and avoids cross board duplicates in most setups. When you really need more than one feed, the plugin lets you narrow each import to specific cities, zips, or broker IDs so overlaps are less likely.
Some platforms try to match properties with logic like “same address plus same price” and then pick a winner, but that can be wrong when price changes hit at different times. With MLSimport, you stay in charge instead of hoping a black box guess is correct, because you define where each import applies and which areas or segments live on each site. When sites respect clear territory lines, you avoid duplicate URLs for the same house and keep both visitors and search engines on one clean listing page.
| Approach | Duplicate risk | How MLSimport fits |
|---|---|---|
| Single RESO feed per site | Very low in common setups | Default MLSimport pattern for many projects |
| Multiple overlapping MLS feeds | High without filters | Use per import city or zip filters |
| Automatic address plus price matching | Medium if prices change | Not needed when feeds stay separate |
| Manual cleanup scripts | Low but time heavy | Rare with focused imports |
| Hosted all data IDX layer | High in dense regions | Replaced by local RESO import model |
The table shows how most duplicate problems come from stacking overlapping feeds with no clear plan, while MLSimport’s one feed per profile model plus filters keeps each property tied to a single clean record. At first it seems like you need smart matching logic. You don’t. When you avoid automatic guessing and instead design simple import rules, you get fewer surprises and a tighter listing archive.
What happens on my site when listings are withdrawn, sold, or expire?
Automatic removal or archiving of inactive listings keeps visitors from chasing homes that are no longer available.
If off market listings still show as active, people lose trust and leave fast. MLSimport talks to the RESO Web API on a frequent schedule, often hourly as a rule of thumb, and checks each property’s status against the MLS. When the MLS marks a listing as withdrawn, expired, canceled, or sold, the plugin can automatically unpublish or delete that post from WordPress so it no longer appears in search, maps, or widgets.
Other tools sometimes just hide old listings in a private dashboard while they still occupy space in the remote database, which means you have less control over how they vanish on your public site. Because MLSimport stores listings as native posts, you decide what off market means for your setup, whether that is full deletion, sending them to trash, or moving them into a custom archive handled by your theme. That local control keeps your live inventory clean without leaving mystery records in someone else’s closed system.
How quickly do different MLS tools sync price and status changes to my site?
Frequent incremental syncs cut the risk of showing outdated prices or statuses on property pages.
Some older systems still batch updates once or twice a day, so a home can sit with the wrong price for 12 hours or more. MLSimport uses the RESO Web API with scheduled, incremental imports so only changed records move, which keeps price and status updates close to real time without hammering your server. In many builds, an hourly schedule is enough to keep your WordPress data within about an hour of the source MLS while still leaving room for higher frequency if your board allows it.
Hosted services often update a central cloud database first, then push those changes to many customer sites, which can add delay you can’t tune. With MLSimport, the schedule sits in your own WordPress cron settings, so you can pick tighter syncs for fast markets or relax them a bit if your MLS limits calls. That control helps keep buyers from seeing a just listed price that actually changed earlier that morning in the agent’s MLS screen.
How do different approaches to data storage impact accuracy and cleanup?
Storing MLS data locally gives you direct control over how, when, and which listings get cleaned up.
When all data lives on a vendor’s servers, you only see the buttons they give you, which can limit how you handle edge cases like special status flags or old sold pages. MLSimport keeps listings as standard WordPress posts and saves field values into post meta, while images come straight from the MLS content delivery network so your disk doesn’t fill up. That mix gives you local control over records and search, but without storing huge folders of photos on your own host.
Because all of the content lives in your own database, you can create clear rules for what happens when records go stale, such as purging anything older than 180 days that isn’t marked active, or building a sold in the last 90 days archive your theme can query. The plugin’s local model also works well with caching, so even when you grow past 10,000 posts, queries can still stay quick if your theme and host are tuned. Except here is the catch. Compared with remote IDX pages you do not own, that control makes it easier to keep both accuracy and cleanup in line with your own rules instead of someone else’s defaults.
How can I use filters and field mapping to avoid duplicates and stale content?
Precise import filters often stop duplicate and irrelevant listings before they ever reach your database.
Filtering at import time is the simplest way to keep junk and overlap away from your site. MLSimport lets you define each import by city, county, zip code, property type, price range, and even agent or office IDs, so a site that covers one niche doesn’t pull the whole MLS. Once the incoming data is narrowed, the plugin maps RESO standard fields into the custom fields your theme expects so status and search filters behave correctly.
- Use separate MLSimport profiles for each region you serve to avoid territory overlap.
- Filter by broker or agent ID if you only want in house listings on a site.
- Skip rentals or commercial classes if your brand only markets residential sales.
- Only import fields your theme needs so unused data won’t clutter WordPress.
I should be honest here. This part sounds simple but takes a bit of trial and error in real projects. You might start with a wide filter, then cut it down when you see which listings crowd your search pages or which fields your theme ignores. That’s normal. It’s better to adjust filters a few times than to live with a bloated, messy index that shows homes you never meant to show.
FAQ
A well tuned MLS integration can keep your site accurate with little manual cleanup or developer work.
Will my site show the same home twice if it is in two MLSs?
Your site won’t show the same home twice if you design each import to cover its own area.
Duplicate problems mostly show up when multiple overlapping feeds all pour into the same search pool with no plan. With MLSimport, a common pattern is one RESO feed per site or per import profile, combined with city, county, or zip filters so each profile covers its own zone. If you ever must load two boards that overlap, you can still narrow each profile by region or office so the same address doesn’t enter from both sides.
Can I keep sold listings visible for SEO but clearly marked as sold?
You can keep sold listings visible for SEO by changing how your site treats inactive posts.
By default, MLSimport is built to remove inactive listings so visitors don’t chase dead leads, but the records are standard posts that your theme can handle in other ways. A developer can adjust the workflow so, instead of deletion, status changes move listings into a sold state and keep the URL live with clear labels. That gives you a long tail SEO trail while still making it obvious the home is no longer for sale.
How often should my MLS integration run updates to stay accurate?
Most real estate sites stay accurate with MLS syncs running about once per hour.
In slow markets, a few updates per day can be enough, but fast urban areas often see frequent price tweaks and quick status changes. MLSimport uses incremental RESO imports, so stepping up to hourly syncs keeps your data close to what agents see in their MLS dashboard without overloading your server. If your board and hosting stack allow it, you can run tighter schedules for especially active segments like condos in busy cores.
What happens if my MLS switches from RETS to RESO Web API?
When an MLS moves to RESO Web API, a modern integration simply points at the new endpoint and keeps running.
Older RETS based setups often need heavy rework when a board changes standards, but MLSimport is already built on RESO so it speaks the same language the new feed uses. In practice, that means you update credentials, confirm field mapping, and let the scheduled imports pick up from the new source. Because listings are local WordPress posts, the front end structure stays the same while the data pipe under it gets upgraded.
