[CONTRIBUTION] Ultimate SEO URLs v2.1 - by Chemo

Recommended Posts

artstyle, when you open a thread, please refrain from posting again about the same subject in another thread *without* pointing an url to it, especially if there is already a reply : http://forums.oscommerce.com/index.php?s=&...t&p=1241379

 

Cheers.

Hello,

Thank you for your reply.

I didn't mean to open a new thread yesterday. I wanted to post in this thread where others have tried the SEO URLS contribution.

Yesterday I noticed the error with the Greek language. However there are errors with the currency and manufacturers/subject. I don't know if these problems are related with the Greek language part or are different.

I checked some member's who have a store url listed and installed the contribution successfully but they have only one currency and/or no manufacturers.

So if anyone has successfully added this contribution with multiple currencies and manufacturers or knows what could cause such a problem please let me know.

Thanks again!

This is a great contribution chemo, but i have found one problem with it while testing it out on my store.

 

After you add an item to the shopping basket directly from a list of products (eg list of all the products from a manufacturer) and then click continue shopping to return to that list of products. If you then try to add another product from the list to the shopping cart directly from the list, it adds the same product as before.

 

Is there any way to fix this?

 

I've also discovered this problem - when you add an item to your cart from a list of products within a category, and then click 'continue shopping' to go back to that list of products, when you hover over the 'Buy Now' button you can see the destination URLs all have the same product id in them. V odd!

 

Have (temporarily) got round this by just hard coding the 'Continue Shopping' button to link to the home page, just so it's still there and customers feel they have somewhere to go next.

 

I tried putting in some javascript to just take people 'back', and this worked fine unless someone updated their cart and then clicked 'continue shopping' the javascript just refreshed that shopping_cart page again.

 

If anyone's got a proper fix it'd be much appreciated!

 

Thanks!

Hi,

I just noticed that I get that too. I didn't notice that before so that's another problem.

 

Thanks and any help is appreciated here too.

hello

 

have you seen my screenshots?

 

Yes and it's an osCsid appended not cPath, oddly it is appended inside the .html. The version you use is 2-2.2e which is buggy and I don't support.

What I can tell you is that the problem is not caused by USU.

 

What I can't tell you is what is wrong with your site based on the information provided.

I have installed your version of useo, fair play for building on the original. I seen someone giving credit to chemo above and calling you somebody but I'd just like to say fair play directly to yourself for first of all wiping out all of the buggy fixes and going back to the original and only making solid permanent changes and supporting so many people in the meantime.

 

I have the same problem as some where the first time i visit the site all my links have blahblah.html?oscid=dfdgdfgdfgdf ... once i click on anything at all then the next set of links will be correct. I thought this was good enough but then google indexed my site and every single page has oscid at the end ... doh!

 

My settings are

Session Directory /tmp

Force Cookie Use False Info

Check SSL Session ID True Info

Check User Agent False Info

Check IP Address False Info

Prevent Spider Sessions True Info

Recreate Session True Info

Session Lifetime 7200 Info

 

 

Use Search-Engine Safe URLs (still in development) false

 

Enable SEO URLs? true

Add cPath to product URLs? false Info

Add category parent to begining of URLs? true Info

Reset SEO URLs Cache false

 

 

I have installed the latest LARGE version of spiders.txt and also have your FWR URL Validation installed.

 

I seen from the guy above that he tried sid killer and it did not work but since his oscid is inside the .html tag i think its a buggy install and sid killer might work for me if you do not have any other suggestions.

 

Other info ... I do have a private SSL, so I can force cookie usage with but I don't really want to as im sure a good 5-10% of people have cookies blocked / old browsers etc. What is the main issues with forcing cookies? If its loosing sales i really don't want to do it haha

 

Thanks so much for your time

That is normal behaviour, osCsid should disappear after a few clicks. If you are having osCsid indexed though that is a major problem.

 

You have prevent spider sessions set to true and recreate session true which would have been my advice. Basically all of the main bots identify themselves and so with a current spiders.txt and prevent spider sessions this can't happen.

 

Is it possible that these session ids were indexed before you had the correct settings in place?

 

Either way it is not a problem related to USU.

Unfortunately no, everything was in place 3-4 days before the bots came onto the site... google stayed 18 hours on the site and i could see from a who is online tool that each page had the oscid :( Then when the pages got updated on google / yahoo etc they had the oscid at the end of every single new page. I'm not sure if this is strange or not but all the oscid were different for each page. So it was like the useo was trying to kill the id but the bot kept picking up new ones.

 

For normal users the oscid goes away after one click but didn't for the bots, maybe they take a screen shot from the start of all the related links and because this is within the first click they all have the oscid attached.

 

The only thing i can think of is that I am using the large version of spider.txt ... maybe I should switch to the smaller version? Do you have SID killer installed or anything like that? And are you just using the latest version of spider.txt in the contributions section (large or small)

 

Thanks again

If you installed 2-2.2e then I'd suggest you install 2.1d updated.

hey fwr ...

It looks like google is correcting itself ... very very strange... maybe they are visiting their existing links that have the oscid and being redirected to the non oscid page and then updating their link to remove it... is this possible? I'll keep you updated on this one if all the oscid are removed from all search engine naturally then thats amazing.

 

On another note, When you click the category its grand, then you click the maker and it goes www.blah.com/category-name-maker-name but then when you click on the product it goes blah.com/product-name

 

Is there anyway to make it go blah.com/maker-name-product-name ?

 

Thanks for your support, your the true legend :)

help I have installed the contribution and it all works well.

The URL that was http://mydomain/catalog/product_info.php?products_id=787

is now coming up as http://mydomain/catalog/pink-lady-jacket-p-787.html and working fine.

However if a link from an external site comes in using the old URL it gets converted to http://mydomain/catalog/product_info.php?c...roduct_info.php

 

Can anyone point me to the area where I have gone wrong?

 

My current httaccess file in my /catalog directory contains:

 

RewriteRule ^(.*)-p-(.*).html$ product_info.php?products_id=$2&%{QUERY_STRING}

RewriteRule ^(.*)-c-(.*).html$ index.php?cPath=$2&%{QUERY_STRING}

In general this works great for me - but I'm having a problem with 301 redirects.

 

We just changed the name of one of our categories, i.e.

old URL: mysite.com/old-category-name-c-31.html

new URL: mysite.com/new-category-name-c-31.html

 

The way the contribution is set up the site will render the same category page (for category #31) either way. However, since the old URL was in the search engines I wanted to do a 301 redirect.

 

I tried to do that in my .hatccess (doing a standard 301 redirect) but the user gets redirected to:

mysite.com/new-category-name-c-31.html?cPath=31

 

How do I remove the "?cPath=31" ?? (i.e. stop it from being appended when we are doing a 301 redirect)

 

This is disabled in the options and none of our other URLs have "?cPath=" in them.

 

Any help would be appreciated.

Hi, im having problems with the buy now buttons, i think it can be related to ultimate seo url (but im not sure...). The thing is, i installed the contrib about a month ago, and have now realised the buy now buttons are not working ok, but i have no idea if they worked at all before installing the contribution... anyway, i hope someone can help me. :)

 

so here's the problem: in a category listing, if i click the thumbnail of a product im supossed to go to the product page, but if i click the "buy now" button, its supossed to show my cart, with the product added to it. right? ok, the problem is, the buy now button seem to take me to the product page, and nothing is included in the cart.

 

also, the link when i click in a thumbnail of a product in a category listing is like www-mydomain-com/some_product-p-30.html, BUT the link when i click in the "buy now" button instead, is www-mydomain-com/-c-7.html?products_id=30&action=buy_now&sort=2a. its supossed to be this way? isnt this url "bad" for the search engines?

 

thanks in advance

If a category has more than 20 items and I click next to go to the next page of products I get sent back to index.php. I've searched the forums for a solution to this problem but still can't figure out what's going on. I have chemo's seo urls contribution installed but none of the fixes for described in the forums work. It's very strange. You can see for yourself here: http://bakerjosh1979.startlogic.com/store/...ds-c-21_42.html

 

I understand this issue has been addressed but if you look at my seo.class.php file I don't have any of the lines of code referred to in the "solutions" for this problem. I'm sure its the same type of problem, but I don't know what to change.

Well thank you Snarf for posting the over 2000 lines of code from chemos seo.class.php

 

I'm sure everyone will enjoy scrolling half a mile down just to read your post.

 

If you are using version 2-2.2e (and I assume from your post that you are) then install 2.1d updated as 2-2.2e doesn't work.

Yeah that is a lot of code.

 

I started with 2.1d, noticed the next page problem, uploaded chemo's latest version- still the same problem. Now I've reuploaded 2.1d. When I click "next" it doesn't work.
